Hutchinson Lupus Pernio Type i

Hutchinson lupus pernio type is an old name that doctors used for a special kind of skin lupus now called chilblain lupus erythematosus (CHLE). It is a long-lasting skin disease where red-purple, swollen patches or bumps appear on fingers, toes, ears, or nose after exposure to cold or damp weather. These areas can be painful or itchy and may crack or ulcerate. Chilblain lupus is a form of chronic cutaneous lupus erythematosus, so it is related to the autoimmune disease systemic lupus, but many patients only have skin disease. Researchers think it happens because the immune system attacks small blood vessels in the skin, especially when cold makes the blood flow slow.DermNet®+1

Hutchinson lupus pernio type is the old name for chilblain lupus erythematosus (CHLE). It is a rare form of cutaneous (skin) lupus that appears as painful, purple-red swollen patches or nodules on fingers, toes, heels, ears, or nose, usually in cold, damp weather.Wikipedia+1 These lesions can itch, burn, or crack and may leave scars or color changes. The disease is autoimmune: the body’s immune system wrongly attacks small blood vessels in the skin. Some patients also have systemic lupus erythematosus (SLE), and a small number have a familial form linked to TREX1 gene variants.Wikipedia+1

Other names

Doctors and books use several other names for Hutchinson lupus pernio type. These names mostly mean the same condition:

Chilblain lupus erythematosus, chilblain lupus, chilblain lupus of Hutchinson, Hutchinson lupus, perniotic lupus, lupus pernio type chilblain lupus, acral chilblain lupus, chronic chilblain lupus lesions, cold-induced cutaneous lupus, and acral lupus erythematosus. These different words reflect that the disease affects cold-exposed acral (tip) areas, is a kind of lupus erythematosus, and was first clearly described by the doctor Jonathan Hutchinson in 1888.PubMed+1

Types

Chilblain lupus (Hutchinson lupus) can be grouped into simple types to help understanding:

• Sporadic (non-familial) chilblain lupus – This is the most common form. It happens in a single person without a strong pattern in the family. It is usually triggered by cold and damp weather and may or may not be linked with systemic lupus.DermNet®+1

• Familial chilblain lupus – This form runs in families and is often caused by a fault (mutation) in a gene called TREX1. This gene normally helps repair DNA. When TREX1 does not work well, the immune system becomes overactive and attacks the skin, especially in the cold.Wikipedia

• Skin-only chilblain lupus – Some patients have lesions only on skin of fingers, toes, ears, or nose, and they do not show clear signs of systemic lupus erythematosus (SLE). These patients still need follow-up, because some may develop systemic disease later.DermNet®+1

• Chilblain lupus associated with SLE or other autoimmune disease – In other patients, chilblain lesions appear together with general lupus features such as joint pain, mouth ulcers, or kidney disease, or with other autoimmune illnesses like Sjögren’s syndrome. These patients have a higher risk of internal organ involvement and need closer monitoring.Wikipedia+1

Causes

Remember: for this disease, “cause” often means risk factor or thing that makes it more likely, not a single simple trigger.

1. Cold exposure
   The most important factor is repeated exposure to cold and damp conditions. Cold makes small blood vessels in the fingers and toes tighten (vasoconstriction). Blood flow slows down, and this can damage the vessel wall and nearby skin, especially in people with lupus-related immune problems.DermNet®+1

2. Chronic wet environment
   Living or working in places that are cold and damp for long periods (for example, standing in cold water or living in poorly heated houses) increases the risk. Wet skin loses heat faster, which makes vessel spasm and skin damage stronger and longer.DermNet®+1

3. Autoimmune reaction against skin and vessels
   In chilblain lupus, the immune system wrongly attacks small blood vessels and skin cells. Immune complexes and auto-antibodies deposit around vessels, causing inflammation, swelling, and purple lesions. This autoimmune mechanism links chilblain lupus with other forms of cutaneous and systemic lupus.Wikipedia+1

4. TREX1 gene mutation (familial form)
   In some families, chilblain lupus is caused by a mutation in the TREX1 gene. This defect allows small pieces of damaged DNA to build up in cells. The body “thinks” these fragments are from viruses, so it activates strong type-I interferon immune pathways, leading to chronic skin inflammation in the cold.Wikipedia

5. Other genetic tendencies to lupus
   Even without a known TREX1 mutation, many patients may have inherited genes that make their immune system more likely to develop lupus and auto-antibodies. These genes interact with environment (like cold) and lead to chilblain-type lesions.Wikipedia+1

6. Anti-Ro/SSA antibodies
   Studies show that many people with chilblain lupus have blood antibodies called anti-Ro/SSA. These auto-antibodies are also common in systemic lupus and Sjögren’s syndrome. Their presence suggests the lupus-type immune reaction is one main driver of skin damage in this disease.Wikipedia+1

7. Female sex hormones
   Women are more often affected by lupus diseases, including chilblain lupus. This may be due to estrogen and other hormones that can increase immune activity and auto-antibody production, making women more sensitive to cold-induced immune skin reactions.DermNet®+1

8. Young to middle-age adult onset
   Chilblain lupus can occur at many ages, but it often appears in teens and young adults. At this time, immune and hormonal changes may help trigger disease in genetically prone people when they experience cold exposure.DermNet®+1

9. Raynaud phenomenon or poor microcirculation
   Raynaud’s phenomenon (fingers turning white, blue, then red in the cold) shows that blood vessels in the fingers over-react to cold. People with Raynaud’s have unstable microcirculation, so when lupus-related inflammation is added, they can develop chilblain lupus lesions more easily.Medscape eMedicine+1

10. Smoking
    Smoking damages blood vessels and worsens peripheral circulation. It also increases oxidative stress and immune activation. Together, these effects can increase the chance that cold exposure and autoimmune activity will create persistent chilblain lesions.Medscape eMedicine+1

11. Coexisting systemic lupus erythematosus (SLE)
    Patients who already have SLE carry auto-antibodies and chronic immune activation. When they are exposed to cold, the same immune system that attacks kidneys or joints can also attack small skin vessels, causing chilblain lupus lesions as part of their cutaneous lupus.Wikipedia+1

12. Other autoimmune diseases (e.g., Sjögren’s syndrome)
    Chilblain lupus has been linked to other autoimmune disorders such as Sjögren’s syndrome, which are also associated with anti-Ro/SSA antibodies. This shows that a general autoimmune background makes the skin more likely to react in this special chilblain pattern.Wikipedia+1

13. Previous chilblains (simple pernio)
    Some patients first have “simple” chilblains (non-lupus pernio) due only to cold, but over time, lesions become chronic and show lupus features. This suggests that repeated cold injury may “open the door” for lupus-type immune reactions in susceptible people.Medscape eMedicine+1

14. High type-I interferon activity
    In familial chilblain lupus, high levels of type-I interferons (immune messenger proteins) are found. Interferons make many immune cells very active and turn on genes that promote inflammation in the skin, especially in cold-exposed acral areas.Wikipedia+1

15. Abnormal clearance of cell debris
    Because TREX1 and related pathways are involved in cleaning up damaged DNA, any problem in this “clean-up” system lets cell fragments remain. The immune system then sees these fragments as danger and starts a chronic inflammatory response, which shows up as persistent lesions.Wikipedia

16. Complement system activation
    In lupus skin disease, complement proteins (part of innate immunity) are activated and deposit in vessel walls and at the dermo-epidermal junction. This contributes to tissue injury and purple discoloration in chilblain lupus lesions.Wikipedia+1

17. Use of certain trigger medicines
    Some medicines that stimulate the immune system, such as interferon or certain biologic therapies, have been reported to make lupus skin disease worse in some patients. In people already prone to lupus, these drugs might help trigger chilblain-pattern lesions after cold exposure.Dermatology Advisor+1

18. Chronic infections that activate immunity
    Long-lasting infections can keep the immune system switched on. In a person with hidden lupus tendency, this extra stimulation might push the immune system into creating auto-antibodies and chilblain lupus lesions, especially when combined with cold injury to vessels.Dermatology Advisor+1

19. Low body mass and poor insulation
    Thin people or those with low body fat lose heat quickly from hands and feet. Their acral skin cools faster and longer, causing more strong vessel spasm and tissue injury, which may favor development of chilblain lupus in predisposed individuals.Medscape eMedicine+1

20. Family history of chilblain lupus or autoimmune disease
    Having close relatives with chilblain lupus, SLE, or related autoimmune diseases suggests shared genes and immune patterns. This family tendency is an important background factor that increases the chance that cold exposure will lead to Hutchinson-type chilblain lupus.PubMed+1

Symptoms

1. Red-purple patches on fingers or toes
   The main sign is red-violet or dusky purple patches or plaques on the backs of fingers and toes. They usually appear during winter or in cold, damp seasons and often stay for weeks or months instead of fading quickly like simple chilblains.DermNet®+1

2. Swelling and puffiness of acral areas
   The affected skin often looks swollen or puffy. This swelling comes from inflammation of small vessels and leakage of fluid into the surrounding tissue, which makes fingers and toes look thick and tight.DermNet®+1

3. Pain or burning in lesions
   Many patients feel pain, burning, or a deep aching sensation in the chilblain lupus patches, especially when the skin is warmed after being cold. This pain is due to inflamed nerves and vessels in the skin.DermNet®+1

4. Itching (pruritus)
   Some lesions are very itchy. Itching comes from inflammatory chemicals and damaged skin barrier. Scratching can worsen the damage, cause cracking, and increase the risk of secondary infection.DermNet®+1

5. Skin ulceration or small sores
   In more severe cases, the tight, swollen, purple skin can break down and form small ulcers or open sores. These ulcers can be painful and slow to heal because the blood supply in these cold-damaged areas is poor.Wikipedia+1

6. Scale and crust on the surface
   The top of the plaques may become scaly or crusted. This reflects ongoing damage to the outer skin layer (epidermis), which sheds more quickly and may be covered with dried fluid or blood.DermNet®+1

7. Color changes with temperature
   Lesions often change color with cold and warmth. They may become darker purple in the cold and more red when rewarmed. This dynamic color change shows how strongly small blood vessels are reacting to temperature.Medscape eMedicine+1

8. Lesions on ears, nose, and sometimes heels
   Although fingers and toes are most common, chilblain lupus lesions can also appear on ears, nose, heels, or other acral skin exposed to cold wind. These areas show similar purple, swollen, tender patches.DermNet®+1

9. Persistence of lesions beyond cold season
   Unlike simple chilblains, which usually go away in a few weeks once the weather improves, chilblain lupus lesions may become chronic and persist for months or even year-round, especially if the underlying autoimmune disease is active.PubMed+1

10. Association with Raynaud attacks
    Some patients also describe classic Raynaud attacks: fingers turn white, then blue, then red when cold. This shows that their blood vessels are overly sensitive and supports the link between chilblain lupus and abnormal microcirculation.Medscape eMedicine+1

11. Nailfold changes
    Under magnification, the skin at the base of the nails (nailfold) may show enlarged or twisted capillaries and small hemorrhages. These microvascular changes are common in autoimmune connective-tissue diseases and match the vessel damage seen in chilblain lupus.Dermatology Advisor+1

12. Cold sensitivity and discomfort
    Patients often say their hands and feet “cannot tolerate” cold. Even mild cold may trigger or worsen lesions and cause severe discomfort, so they may avoid outdoor activities or feel anxious in cold seasons.DermNet®+1

13. General fatigue or malaise
    Some people with chilblain lupus, especially those with associated systemic lupus, feel tired, weak, or “unwell” in general. This fatigue may come from chronic inflammation and immune activation, not only from the skin lesions.Wikipedia+1

14. Joint pains (arthralgia)
    Painful joints, especially small joints of the hands, can occur along with chilblain lesions. This suggests more systemic autoimmune involvement and should make doctors check for full systemic lupus or related diseases.Wikipedia+1

15. Emotional distress and cosmetic concern
    Visible purple lesions on fingers, toes, nose, or ears can be upsetting and embarrassing. Chronic pain, fear of cold, and worry about scarring or systemic lupus can all contribute to anxiety and low mood in affected people.mjrheum.org+1

Diagnostic tests

Doctors diagnose Hutchinson lupus pernio type (chilblain lupus) by combining history, physical exam, and tests. They must rule out simple chilblains, frostbite, vasculitis, and sarcoidosis-related lupus pernio (a different disease).Wikipedia+1

Physical examination tests

1. Full skin inspection
   The doctor carefully looks at all skin, especially fingers, toes, ears, and nose. They note the color (red-purple), shape, swelling, scale, and any ulcers. The pattern on cold-exposed acral areas strongly points toward chilblain lupus in the right clinical setting.DermNet®+1

2. Palpation of lesions
   The lesions are gently touched to feel if they are firm, tender, warm, or cold. In chilblain lupus they are often slightly firm and tender, showing chronic inflammation of the deeper skin and small vessels rather than just superficial irritation.DermNet®+1

3. Assessment of ulceration and secondary infection
   The doctor checks for cracks, ulcers, and signs of infection such as pus, yellow crust, or strong redness around the lesion. This helps decide the severity of the skin damage and whether antibiotics or wound care are needed.DermNet®+1

4. Evaluation for Raynaud phenomenon
   The clinician asks about triphasic color changes (white-blue-red) in fingers when cold and looks for color changes during the visit, if safe. Presence of Raynaud supports an underlying connective-tissue disease related to chilblain lupus.Medscape eMedicine+1

Manual / bedside tests

5. Capillary refill test
   The doctor presses on a fingertip until it blanches white, then releases and counts how quickly pink color returns. Delayed capillary refill suggests poor blood flow in small vessels and supports a circulatory contribution to the lesions.Medscape eMedicine+1

6. Nailfold capillaroscopy (simple handheld method)
   With a small magnifier or dermatoscope, the doctor looks at tiny blood vessels at the nailfold. Enlarged, twisted, or missing capillaries and small hemorrhages hint at an autoimmune connective-tissue process rather than simple chilblains.Dermatology Advisor+1

7. Cold provocation (careful bedside exposure)
   In some centers, a controlled mild cold test is done to see how quickly lesions or color changes appear when skin is cooled. This test is used carefully and rarely, but it can show strong cold sensitivity compatible with chilblain-type disease.Medscape eMedicine+1

Laboratory and pathological tests

8. Complete blood count (CBC)
   CBC looks at red cells, white cells, and platelets. In simple skin-limited chilblain lupus, results may be normal. In systemic lupus or other autoimmune conditions, anemia, low white cells, or low platelets may be found, pointing to wider disease.Dermatology Advisor+1

9. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP)
   ESR and CRP measure inflammation in the body. They may be mildly raised in autoimmune disease. Normal values do not rule out chilblain lupus, but raised levels support the presence of systemic inflammation.Dermatology Advisor+1

10. Antinuclear antibody (ANA) test
    ANA is a key screening test for lupus and other autoimmune diseases. Many patients with chilblain lupus have a positive ANA, which supports the diagnosis and may prompt more specific auto-antibody testing.Wikipedia+1

11. Anti-Ro/SSA and other extractable nuclear antibodies
    Testing for anti-Ro/SSA, anti-La/SSB, and related antibodies helps confirm the autoimmune nature of chilblain lupus. Anti-Ro antibodies are found in many cases and link the disease to lupus and Sjögren’s syndrome.Wikipedia+1

12. Complement levels (C3, C4)
    Complement proteins can be low in systemic lupus because they are used up in immune reactions. Low complement suggests more active or systemic disease, whereas normal levels may occur in skin-limited chilblain lupus.Dermatology Advisor+1

13. Cryoglobulin and cold agglutinin tests
    These tests look for abnormal proteins that clump in the cold and can cause cold-induced skin lesions. In chilblain lupus, these studies are typically negative, and this finding is used in some diagnostic criteria to distinguish from other cold-protein disorders.Wikipedia+1

14. Skin biopsy (histopathology)
    A small piece of affected skin is taken under local anesthesia. Under the microscope, doctors usually see changes typical of lupus: inflammation at the dermo-epidermal junction, perivascular lymphocytes, and sometimes mucin. This is one of the strongest tests to confirm chilblain lupus.PubMed+1

15. Direct immunofluorescence (DIF) of skin
    In this test, special dyes attach to antibodies and complement in the skin sample. A “lupus band” (deposits of immunoglobulins and complement along the basement membrane) supports the diagnosis of lupus-related skin disease, including chilblain lupus.Wikipedia+1

Electrodiagnostic tests

16. Nerve conduction studies (if neuropathy is suspected)
    When patients have numbness, tingling, or suspected nerve damage in hands or feet, nerve conduction studies can check how well electrical signals travel along nerves. Usually these tests are normal in chilblain lupus, helping rule out other neuropathies.Dermatology Advisor+1

17. Electrocardiogram (ECG) in systemic lupus patients
    In patients with known systemic lupus and chilblain lesions, an ECG may be done to see if inflammation also affects the heart. While not specific for chilblain lupus, it helps monitor organ involvement in the broader autoimmune disease.Dermatology Advisor+1

Imaging tests

18. Doppler ultrasound of peripheral vessels
    Ultrasound can look at blood flow in arteries and veins of the limbs. It helps rule out other causes of acral lesions, such as arterial blockages or blood clots, and can show if larger vessels are normal while only small vessels are involved.Dermatology Advisor+1

19. High-frequency skin ultrasound or dermatoscopy imaging
    Some centers use high-frequency ultrasound or digital dermatoscopy to visualize the skin and microvessels. These imaging tools show thickness of skin layers and vascular patterns and can support a chronic inflammatory process like chilblain lupus.Dermatology Advisor+1

20. Chest imaging when systemic disease is suspected
    If blood tests or symptoms suggest systemic lupus or another autoimmune disorder, chest X-ray or CT scans may be done to look for lung or heart involvement. These imaging tests do not diagnose chilblain lupus directly but help assess the full extent of autoimmune disease.Dermatology Advisor+1

Non-pharmacological treatments (therapies and others)

1. Protection from cold and damp

The most important non-drug treatment is strict protection from cold and damp weather. Patients are advised to wear warm gloves, socks, boots, and ear protection, and to avoid sudden temperature changes, wet shoes, or staying outside in cold wind for long periods.PMC+1

Purpose: Reduce flares and help existing lesions heal.
Mechanism: Warmth prevents cold-induced vasoconstriction and micro-vascular injury that trigger the inflammatory rash in chilblain lupus.Wikipedia+1

---

2. Layered clothing and thermal socks

Using many thin layers of clothing and thermal socks keeps hands and feet evenly warm. Moisture-wicking inner layers and waterproof outer layers help keep skin dry.MJR+1

Purpose: Maintain stable skin temperature and avoid chilling after sweating.
Mechanism: Layering traps warm air, reduces heat loss, and prevents the rapid cooling that worsens blood vessel spasm in acral skin.Clinical Gate+1

---

3. Gentle re-warming after cold exposure

If hands or feet get cold, re-warming should be slow and gentle (for example, using lukewarm water or warm blankets, not hot water or direct heaters).Clinical Gate

Purpose: Relieve symptoms without damaging skin.
Mechanism: Gradual warming lets small vessels reopen slowly, avoiding sudden reperfusion and further endothelial injury, which can worsen swelling and pain.Wikipedia+1

---

4. Smoking cessation

Nicotine causes strong narrowing of blood vessels and reduces oxygen to skin. In people with chilblain lupus, smoking is linked to more severe, more persistent lesions.The Hospitalist+1

Purpose: Improve blood flow and reduce flares.
Mechanism: Stopping smoking removes constant vasoconstriction and oxidative stress, improving micro-circulation and allowing inflamed skin to heal faster.Clinical Gate+1

---

5. Sun protection and photoprotection

Because chilblain lupus is a form of cutaneous lupus, ultraviolet (UV) light can worsen disease activity. Daily broad-spectrum sunscreen, hats, and avoiding midday sun are recommended even in winter.WHO+1

Purpose: Prevent new lesions and reduce overall lupus activity.
Mechanism: UV light increases autoantigen exposure and interferon-driven immune pathways, which can aggravate cutaneous lupus lesions, including CHLE.WHO+1

---

6. Emollients and barrier repair creams

Regular use of bland emollients (like petrolatum or ceramide creams) keeps the skin soft, reduces cracking, and protects from friction.PMC+1

Purpose: Lower pain, fissures, and risk of infection.
Mechanism: Occlusive and barrier-repair creams reduce transepidermal water loss, support the stratum corneum, and limit entry of irritants and microbes into already inflamed skin.PMC+1

---

7. Gentle wound care of ulcers and fissures

If lesions crack or ulcerate, careful cleaning with mild antiseptic, non-adhesive dressings, and pressure off-loading are needed.Cleveland Clinic+1

Purpose: Prevent secondary bacterial infection and scarring.
Mechanism: Good wound care reduces bacterial load, maintains moist but not macerated healing conditions, and protects newly formed tissue from trauma.Cleveland Clinic+1

---

8. Avoiding tight shoes, gloves, and rings

Tight shoes, gloves, or rings can cut off circulation in already vulnerable digits. Changing to wide, padded footwear and loose gloves helps comfort and blood supply.Clinical Gate+1

Purpose: Reduce pressure-induced ischemia and pain.
Mechanism: Reduced mechanical compression improves capillary blood flow and lowers the risk of tissue necrosis in acral skin.Clinical Gate+1

---

9. Regular gentle exercise

Walking, finger and toe movements, and simple aerobic exercise improve overall circulation and cardiovascular health.Clinical Gate+1

Purpose: Support blood flow to the extremities and reduce stiffness.
Mechanism: Muscle activity promotes vasodilation, increases cardiac output, and improves endothelial function, which all support micro-circulation in the skin.Clinical Gate+1

---

10. Occupational and lifestyle modifications

Some jobs or hobbies require long exposure to cold water, metal, or outdoor work. Adjusting working hours, using protective gear, or changing tasks can reduce daily cold exposure.Clinical Gate+1

Purpose: Prevent repetitive triggers that keep lesions chronic.
Mechanism: Reducing occupational cold and moisture exposure lowers repeated vasospasm and micro-trauma that maintain inflammation.Clinical Gate+1

---

11. Stress management techniques

Chronic pain and appearance changes can cause anxiety and low mood. Relaxation, breathing exercises, counseling, and support groups help many patients.PMC+1

Purpose: Improve quality of life and treatment adherence.
Mechanism: Stress hormones such as cortisol and adrenaline can modulate the immune system and vascular tone; stress reduction may indirectly reduce flares and improve coping.clinexprheumatol.org+1

---

12. Sleep hygiene

Good sleep habits (regular sleep schedule, quiet dark room, limiting screens) support immune balance and healing.clinexprheumatol.org

Purpose: Help the body repair damaged skin and reduce fatigue.
Mechanism: During deep sleep, cytokine patterns and hormonal signals favor tissue repair and regulation of autoimmune responses, which can benefit chronic inflammatory skin diseases.clinexprheumatol.org+1

---

13. Avoiding vibrating tools and repetitive trauma

Use of vibrating tools or repeated tapping may injure tiny vessels and nerves in fingers and toes. Patients are advised to limit such exposure or use anti-vibration gloves.Clinical Gate+1

Purpose: Reduce mechanical aggravation of lesions.
Mechanism: Lowering micro-trauma reduces endothelial damage and local release of inflammatory mediators, which in turn can decrease flares.Clinical Gate+1

---

14. Control of associated autoimmune disease

Because some people with CHLE also have SLE or other autoimmune diseases, regular rheumatology care and controlling systemic disease activity are important.PMC+1

Purpose: Prevent systemic flares that worsen skin lesions.
Mechanism: Disease-modifying treatment for SLE reduces autoantibody load and immune complex formation, indirectly calming skin inflammation in chilblain lesions.WHO+1

---

15. Vitamin D optimization (through safe sun and diet)

People who avoid sun for lupus often have low vitamin D levels, which can affect bone health and immune function. Doctors sometimes advise diet changes or supplements after blood tests.WHO+1

Purpose: Support bone, muscle, and immune systems.
Mechanism: Vitamin D modulates T-cell and B-cell activity and may help balance autoimmune responses, though evidence in CHLE is indirect.WHO+1

---

16. Psychological support and body-image counseling

Lesions on fingers, toes, or nose can be embarrassing. Talking with a psychologist or counselor familiar with chronic skin disease may help.PMC+1

Purpose: Reduce depression, social withdrawal, and treatment fatigue.
Mechanism: Emotional support improves coping skills, which can lead to better self-care, adherence to cold protection, and earlier reporting of complications.PMC+1

---

17. Patient education materials

Clear written information on chilblain lupus, triggers, and self-care helps patients and families understand the condition.Cleveland Clinic+1

Purpose: Empower patients to participate in care and spot warning signs.
Mechanism: Education improves knowledge, which leads to quicker behavior changes such as better protection from cold and early consultation when lesions change.Cleveland Clinic+1

---

18. Hand and foot physiotherapy

For long-standing disease with stiffness, physiotherapists can teach range-of-motion and strengthening exercises for hands and feet.PMC+1

Purpose: Preserve mobility and function.
Mechanism: Movement stimulates blood flow, preserves joint range, and prevents contractures that might follow chronic painful lesions.PMC+1

---

19. Compression stockings (for selected cases)

Mild compression stockings may be used in patients who also have venous insufficiency or edema of the legs, under medical guidance.Clinical Gate+1

Purpose: Improve venous return and reduce dependent swelling.
Mechanism: External pressure supports superficial veins, lowers venous pooling, and can indirectly improve arterial inflow to skin.Clinical Gate+1

---

20. Regular follow-up with dermatology and rheumatology

Because CHLE can sometimes be the first sign of systemic lupus or other autoimmune disease, regular check-ups and blood tests are important.PMC+1

Purpose: Detect systemic involvement early and adjust treatment.
Mechanism: Monitoring ANA, complement, and organ function allows clinicians to escalate or de-escalate therapy and prevent long-term damage.PMC+1

---

Drug treatments

Important: The drugs below are used for cutaneous lupus and/or chilblain lupus under specialist supervision. Many uses are off-label for this rare disease.

Dietary molecular supplements (supportive, not cures)

Always discuss supplements with your own doctor, especially if you already take immunosuppressive drugs or have kidney or liver disease.

1. Omega-3 fatty acids (fish oil) – 1–3 g/day EPA+DHA is often used to help general inflammation; omega-3s shift eicosanoid balance toward anti-inflammatory mediators and may modestly reduce autoimmune activity.clinexprheumatol.org

2. Vitamin D – Doses depend on blood level; vitamin D supports bone health and immune regulation, and deficiency is common in photosensitive lupus because of sun avoidance.WHO+1

3. Vitamin C – 200–500 mg/day is commonly used; vitamin C acts as an antioxidant and supports collagen and wound healing in cracked, ulcerated lesions.clinexprheumatol.org

4. Vitamin E – As a fat-soluble antioxidant, vitamin E may help limit oxidative damage in skin and vessels; doses must stay within safe limits to avoid bleeding risk.clinexprheumatol.org

5. Zinc – 10–25 mg/day can support skin repair and immune function; zinc is involved in keratinocyte growth and many immune enzymes but high doses can cause copper deficiency.clinexprheumatol.org

6. Selenium – At nutritional doses (~50–100 µg/day), selenium is a cofactor for antioxidant enzymes like glutathione peroxidase and may modulate autoimmunity.clinexprheumatol.org

7. Curcumin (turmeric extract) – Curcumin has anti-inflammatory and antioxidant effects through NF-κB and cytokine modulation; it is studied in rheumatic disease but data in CHLE are limited.clinexprheumatol.org

8. Green tea polyphenols (EGCG) – EGCG has immune-modulating and antioxidant activity and may help endothelial function; however, high doses can affect liver function.clinexprheumatol.org

9. Probiotics – Selected probiotic strains may support gut barrier and immune tolerance, which could indirectly influence autoimmune skin disease.clinexprheumatol.org

10. L-arginine or L-citrulline – These amino acids are nitric-oxide precursors and may improve endothelial function and vasodilation; they must be used cautiously in people with vascular disease.Clinical Gate+1

6 Immunity-modulating / regenerative / “stem-cell–related” approaches

1. Belimumab – A biologic that blocks BAFF/BLyS, approved for SLE; in severe systemic lupus with cutaneous involvement it may reduce flares and steroid need, indirectly helping CHLE.clinexprheumatol.org+1

2. Rituximab – Anti-CD20 antibody that depletes B-cells, used off-label in difficult lupus; by reducing autoantibodies it can improve severe skin disease in some patients.ScienceDirect+1

3. Anifrolumab – Targets type I interferon receptor, recently approved for SLE; interferon pathways are key in cutaneous lupus, so blocking them can reduce lesion activity.clinexprheumatol.org+1

4. Autologous hematopoietic stem cell transplantation (HSCT) – In extremely severe, life-threatening autoimmune disease, HSCT “resets” the immune system by high-dose immunoablation followed by stem-cell rescue.clinexprheumatol.org

5. Mesenchymal stem cell therapy (experimental) – Investigational infusions of mesenchymal stem cells aim to provide immunoregulatory and tissue-repair effects; data are still limited and it is not standard care.clinexprheumatol.org

6. IVIG as immune “reset” – Already listed above, IVIG can be considered a “biologic” immunomodulator, changing autoantibody handling and Fc receptor signaling in severe disease.JCAD+1

(All these approaches are specialist, hospital-level therapies, not routine for most people with Hutchinson lupus pernio type.)

Surgeries (procedures and why they are done)

1. Excision of severely damaged lesions – In rare cases with fixed, painful plaques or ulcerated tissue, surgical removal of the lesion may be performed to remove scarred or non-healing skin.DermNet®+1

2. Full-thickness skin grafting – After excision of badly damaged acral skin, a full-thickness graft from a healthy site can restore cover, improve appearance, and protect underlying structures.DermNet®+1

3. Debridement of necrotic tissue – If extreme cold injury or infection leads to dead tissue, careful surgical debridement helps healing and reduces infection risk.DermNet®+1

4. Digital reconstructive surgery – In cases with deformity of fingers or toes, reconstructive procedures may improve function and cosmetic appearance.DermNet®+1

5. Sympathectomy (very rare) – Surgical interruption of sympathetic nerves may be considered only in extreme refractory vascular disease to improve blood flow; this is exceptional and not standard.Clinical Gate+1

When to see doctors

You should see a doctor (preferably a dermatologist or rheumatologist) if you notice purple-red, painful or itchy patches on fingers, toes, ears, or nose after cold exposure that do not disappear in a few days, especially if they ulcerate or leave scars.PMC+1 Seek urgent care if lesions become very painful, black, or foul-smelling (possible necrosis or infection), if you develop fever, joint pain, chest pain, shortness of breath, or other symptoms that may suggest systemic lupus or another organ problem.PMC+1 Regular follow-up is also important if you already have lupus or chilblain lupus to monitor blood tests and organ function.clinexprheumatol.org+1

What to eat and what to avoid”

1. Eat: Plenty of fruits and vegetables (rich in antioxidants) to support skin repair and general health.clinexprheumatol.org

2. Eat: Whole grains, legumes, and nuts for fiber and stable blood sugar, helping vascular health.clinexprheumatol.org

3. Eat: Oily fish (salmon, sardines) 1–2 times per week for omega-3 fatty acids.clinexprheumatol.org

4. Eat: Adequate protein (fish, poultry, eggs, pulses) to support tissue healing.clinexprheumatol.org

5. Eat: Foods rich in vitamin D and calcium (fortified milk, yogurt) if sun exposure is limited, according to local guidance.WHO+1

6. Avoid: Very high-salt processed foods that can worsen blood pressure and edema.clinexprheumatol.org

7. Avoid: Excess sugar-sweetened drinks and refined carbohydrates, which may increase inflammation and vascular risk.clinexprheumatol.org

8. Avoid: Too much alcohol, which can harm liver function and interact with many lupus drugs.clinexprheumatol.org

9. Avoid: Crash diets or extreme fasting, which can weaken immunity and delay wound healing.clinexprheumatol.org

10. Avoid: Unproven “immune-boosting” herbal mixes without medical advice, because of drug interactions and lack of strong evidence.clinexprheumatol.org

Frequently asked questions (FAQs)

1. Is Hutchinson lupus pernio type the same as lupus pernio from sarcoidosis?
No. Hutchinson lupus pernio type refers to chilblain lupus erythematosus, a form of cutaneous lupus; sarcoid lupus pernio is a type of cutaneous sarcoidosis. They look similar but have different causes and treatments.Wikipedia+2Dermatology Advisor+2

2. Is it a form of cancer?
No, chilblain lupus is not a cancer. It is an autoimmune disease that affects small blood vessels in the skin. However, long-term strong immunosuppressive drugs can slightly increase some cancer risks, so regular monitoring is needed.PMC+2clinexprheumatol.org+2

3. Can chilblain lupus turn into systemic lupus?
Some patients with CHLE also have systemic lupus or may later develop it, but many never do. Estimates suggest a minority (around 15–20% in some series) develop systemic disease, so regular follow-up and blood tests are important.PMC+2DermNet®+2

4. Is the disease life-threatening?
On its own, skin-limited CHLE is usually not life-threatening, but it can be painful, chronic, and scarring. When associated with systemic lupus or other organ involvement, the overall condition can be more serious.PMC+2clinexprheumatol.org+2

5. Does chilblain lupus ever go away completely?
Many people have a chronic course with flares in cold seasons and calmer periods in warm weather. With good cold protection and proper treatment, lesions often improve a lot, but some patients continue to have recurrent episodes.PMC+2DermNet®+2

6. Are children and teenagers affected?
Yes, CHLE can occur in young people, including familial forms due to TREX1 mutations. These cases may show early onset and a strong link to cold exposure.Wikipedia+2PMC+2

7. How is the diagnosis confirmed?
Doctors use history (cold-related lesions), physical examination, skin biopsy showing lupus-type changes, and blood tests for autoantibodies and complement. They also rule out other causes of chilblains and vasculitis.PMC+2DermNet®+2

8. What is the difference between simple chilblains and chilblain lupus?
Simple chilblains usually appear after cold exposure and go away in a few weeks, with normal blood tests. Chilblain lupus lesions last much longer, may scar, and biopsy plus blood tests show lupus features or autoantibodies.Clinical Gate+2PMC+2

9. Can I still go outside in winter?
Yes, but you need very careful protection: warm, dry layers, proper footwear and gloves, and limiting time in extreme cold or damp. Many people can live fairly normal lives with these precautions.PMC+2PMC+2

10. Is hydroxychloroquine safe long-term?
Hydroxychloroquine is widely used long-term in lupus and has a relatively favorable safety profile, especially compared with steroids, but it needs regular eye checks and dose control to avoid retinal toxicity.FDA Access Data+2FDA Access Data+2

11. Why do doctors worry about eye problems with antimalarials?
Hydroxychloroquine and chloroquine can slowly build up in the retina and cause permanent visual damage. Keeping the dose within safe limits and having regular eye examinations greatly lowers this risk.FDA Access Data+2FDA Access Data+2

12. Are “immune boosters” good for this disease?
For autoimmune diseases like chilblain lupus, you usually do not want to boost the immune system; you want to balance or calm it. Many marketed “immune boosters” may conflict with prescribed immunosuppressive drugs, so always ask your doctor.clinexprheumatol.org+1

13. Can diet alone cure chilblain lupus?
No diet can cure CHLE. However, a healthy anti-inflammatory style diet, plus not smoking and staying warm, can support your overall health and may help medicines work better.clinexprheumatol.org+1

14. Do I need surgery?
Most patients never need surgery. Surgery is considered only for severe, structurally damaged, or non-healing areas where medical treatment has failed.DermNet®+1

15. What is the most important thing I can do myself?
The single most important self-care step is constant cold and damp protection for your hands, feet, ears, and nose, combined with not smoking and keeping regular follow-up with your specialists.PMC+2Clinical Gate+2
