Definition

Erythematosus profundus is a general term used to describe a group of diseases characterized by skin rashes and joint . The term “erythematosus” refers to the redness of the skin, while “profundus” means “deep.” These diseases are part of a larger group of autoimmune conditions known as connective tissue diseases.

There are several different types of erythematosus profundus, including:

  1. (): SLE is a that can affect many different parts of the body, including the skin, joints, , brain, and heart. It is characterized by a butterfly-shaped on the face, as well as joint and .
  2. Discoid Erythematosus (DLE): DLE is a form of lupus that affects only the skin. It is characterized by coin-shaped red patches on the face, neck, and scalp that may become scaly and discolored.
  3. Cutaneous Lupus Erythematosus (SCLE): SCLE is a type of lupus that affects only the skin. It is characterized by circular or butterfly-shaped rashes that appear on sun-exposed areas of the body, such as the arms and neck.
  4. Drug-Induced Lupus Erythematosus (DIL): DIL is a form of lupus that is triggered by certain medications. It can cause symptoms similar to SLE but typically resolves once the offending medication is stopped.
  5. Mixed Connective Tissue Disease (MCTD): MCTD is a rare autoimmune disease that combines features of several different connective tissue diseases, including lupus, scleroderma, and polymyositis. It is characterized by skin rashes, joint pain, and inflammation of the .

All of these types of erythematosus profundus are caused by the immune system mistakenly attacking healthy tissues in the body. The exact cause of these diseases is not well understood, but a combination of and environmental factors is thought to play a role.

Symptoms

Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease that can affect many parts of the body, including the skin, joints, kidneys, heart, lungs, brain, and blood cells. One form of SLE is called deep erythematosus (also known as discoid lupus erythematosus), which primarily affects the skin.

Here is a list of symptoms commonly associated with deep erythematosus:

  1. Rash: A rash is a common symptom of deep erythematosus, which typically appears as red, scaly patches on the face, neck, or scalp. The rash may be itchy and may sometimes blister.
  2. Photosensitivity: People with deep erythematosus are often sensitive to sunlight, and exposure to the sun may trigger a flare-up of symptoms.
  3. Mouth ulcers: Mouth ulcers are painful sores that can develop inside the mouth, and they are a common symptom of deep erythematosus.
  4. Joint pain and swelling: Joint pain and swelling are common in people with deep erythematosus, and they may also experience stiffness and decreased range of motion.
  5. Fatigue: Fatigue is a common symptom of deep erythematosus, and it may be severe enough to interfere with daily activities.
  6. Fever: People with deep erythematosus may experience fever, which is often a sign of an underlying infection or inflammation.
  7. Anemia: Anemia, or a low red blood cell count, is a common complication of deep erythematosus, and it can cause fatigue, weakness, and shortness of breath.
  8. Hair loss: Hair loss is a common symptom of deep erythematosus, and it may be accompanied by thinning or patchy hair.
  9. Raynaud’s phenomenon: Raynaud’s phenomenon is a condition in which the fingers and toes become pale and cold in response to stress or cold temperatures.
  10. Numbness or tingling: Numbness or tingling in the hands and feet is a common symptom of deep erythematosus, and it may be accompanied by muscle weakness.
  11. Dry eyes: Dry eyes are a common symptom of deep erythematosus, and they can cause discomfort, irritation, and sensitivity to light.
  12. Chest pain: Chest pain is a common symptom of deep erythematosus, and it may be accompanied by shortness of breath or a rapid heartbeat.
  13. Swollen glands: Swollen glands, or lymph nodes, are a common symptom of deep erythematosus, and they may be accompanied by fatigue, fever, or night sweats.
  14. Depression: Depression is a common complication of deep erythematosus, and it may be caused by the physical and emotional toll of the disease.
  15. Memory problems: Memory problems, such as forgetfulness or confusion, are a common symptom of deep erythematosus, and they may be related to inflammation or other underlying medical conditions.
  16. Headaches: Headaches are a common symptom of deep erythematosus, and they may be accompanied by neck pain, fatigue, or sensitivity to light.
  17. Muscle pain: Muscle pain is a common symptom of deep erythematosus, and it may be accompanied by weakness, cramping, or stiffness.

Diagnosis

The diagnosis of SLE can be challenging, as it often presents with a wide range of symptoms and can mimic other diseases. Here are different tests and diagnoses that can be used to diagnose SLE and erythematosus profundus:

  1. Complete Blood Count (CBC): This test measures the number of red and white blood cells and platelets in the blood. Abnormalities in these cells can be a sign of SLE.
  2. Erythrocyte Sedimentation Rate (ESR) and C-Reactive Protein (CRP) Test: These tests measure inflammation in the body and can be elevated in people with SLE.
  3. Antinuclear Antibody (ANA) Test: This test looks for antibodies in the blood that are directed against the body’s own cells and tissues. A positive ANA test is often present in people with SLE.
  4. Anti-dsDNA Antibody Test: This test looks for antibodies against double-stranded DNA, which are often present in people with SLE and can indicate disease activity.
  5. Anti-Ro (SSA) and Anti-La (SSB) Antibody Tests: These tests look for antibodies against the Ro (SSA) and La (SSB) proteins, which are associated with SLE and other autoimmune diseases.
  6. Complement Levels Test: This test measures the levels of complement, a group of proteins in the blood that help fight infections and inflammation. Low levels of complement can be a sign of SLE.
  7. Lupus Anticoagulant Test: This test measures the tendency of blood to clot and can be elevated in people with SLE.
  8. Anti-Smith (Sm) Antibody Test: This test looks for antibodies against the Smith (Sm) protein, which are associated with SLE.
  9. Anti-RNP Antibody Test: This test looks for antibodies against ribonucleoproteins, which are associated with SLE and other autoimmune diseases.
  10. Anti-SSA/Ro and Anti-SSB/La Antibody Tests: These tests look for antibodies against the SSA/Ro and SSB/La proteins, which are associated with SLE and other autoimmune diseases.
  11. Kidney Function Tests: These tests measure how well the kidneys are functioning and can detect early signs of kidney damage, which is a common complication of SLE.
  12. Chest X-Ray: This test produces images of the chest and can detect signs of lung involvement in SLE, such as pleural effusions or lung infiltrates.
  13. Electrocardiogram (ECG) and Echocardiogram: These tests measure the electrical and mechanical activity of the heart and can detect signs of heart involvement in SLE, such as pericarditis or myocarditis.
  14. Neurological Exam: This test assesses the function of the nervous system and can detect signs of neurological involvement in SLE, such as seizures or confusion.
  15. Skin Biopsy: This test involves removing a small sample of skin for examination under a microscope. It can confirm the diagnosis of erythematosus profundus and determine the extent of skin involvement in SLE.

Treatment

While there is no cure for SLE, there are various treatments available to help manage its symptoms and prevent flare-ups. Here are 20 treatments for DLE:

  1. Topical corticosteroids: Topical corticosteroids, such as hydrocortisone, are a common first-line treatment for DLE. They can reduce inflammation and itching, and help to improve the appearance of the skin.
  2. Sun protection: Sun exposure can trigger flare-ups of DLE, so it’s important to protect the skin from the sun. This can be done by wearing protective clothing, using a high-SPF sunscreen, and avoiding prolonged sun exposure.
  3. Moisturizers: Moisturizing the skin can help to reduce itching and improve the appearance of the skin. It’s important to use a fragrance-free and non-irritating moisturizer.
  4. Antimalarials: Antimalarials, such as hydroxychloroquine, are commonly used to treat SLE, including DLE. They help to reduce inflammation and can also prevent flare-ups.
  5. Topical calcineurin inhibitors: Topical calcineurin inhibitors, such as pimecrolimus and tacrolimus, are another option for treating DLE. They work by suppressing the immune system, which helps to reduce inflammation.
  6. Topical retinoids: Topical retinoids, such as tretinoin, can help to improve the appearance of the skin by promoting skin cell turnover.
  7. Phototherapy: Phototherapy, also known as light therapy, involves exposing the skin to a specific type of light. This can help to reduce inflammation and improve the appearance of the skin.
  8. Systemic corticosteroids: In severe cases of DLE, systemic corticosteroids, such as prednisone, may be needed. These are taken orally and work by reducing inflammation throughout the body.
  9. Immunosuppressants: Immunosuppressants, such as azathioprine and mycophenolate mofetil, can help to suppress the immune system, which can reduce inflammation and prevent flare-ups.
  10. Laser therapy: Laser therapy can help to improve the appearance of the skin by reducing redness and inflammation.
  11. Cryotherapy: Cryotherapy involves freezing the skin with liquid nitrogen. This can help to reduce inflammation and improve the appearance of the skin.
  12. Microdermabrasion: Microdermabrasion is a type of exfoliation that can help to improve the appearance of the skin by removing dead skin cells and promoting skin cell turnover.
  13. Chemical peels: Chemical peels use chemicals to exfoliate the skin and improve its appearance. They can also help to reduce inflammation and improve the texture of the skin.
  14. Topical immunomodulators: Topical immunomodulators, such as imiquimod, can help to reduce inflammation by
  15. Ultraviolet (UV) Light Therapy: UV light therapy involves exposing the skin to artificial UV light in a controlled environment. It can help reduce inflammation and improve the appearance of deep erythema.
  16. Phototherapy: Phototherapy is a type of therapy that involves exposing the skin to specific types of light in a controlled environment. It can help reduce inflammation and improve the appearance of deep erythema.
  17. Biologic Drugs: Biologic drugs are medications that are made from living cells or tissues. They are used to treat a variety of autoimmune diseases, including SLE, and can help reduce inflammation and prevent skin rashes from getting worse.
  18. Antibiotics: Antibiotics are medications that are used to treat infections. If deep erythema is caused by a bacterial infection, antibiotics may be prescribed to help clear up the infection.
  19. Antidepressants: Antidepressants are medications that are used to treat depression and other mood disorders. They can also be used to treat certain symptoms of SLE, including chronic pain and fatigue.
  20. Anticonvulsants: Anticonvulsants are medications that are used to treat seizures. They can also be used to treat certain symptoms of SLE, including chronic pain and fatigue.

Doctor visit helper

Prepare before seeing a doctor

A simple rural-patient checklist to help you explain symptoms clearly, ask better questions, and avoid unsafe self-treatment.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Start with a registered doctor or the nearest qualified health center.

What to tell the doctor

  • Write when the problem started and how it changed.
  • Bring old prescriptions, investigation reports, and current medicines.
  • Write allergies, pregnancy status, diabetes, kidney/liver disease, and major past illnesses.
  • Bring one family member if the patient is weak, elderly, confused, or a child.

Questions to ask

  • What is the most likely cause of my symptoms?
  • Which danger signs mean I should go to hospital quickly?
  • Which tests are necessary now, and which can wait?
  • How should I take medicines safely and what side effects should I watch for?
  • When should I come for follow-up?

Tests to discuss

  • Vital signs: temperature, pulse, blood pressure, oxygen saturation
  • Basic physical examination by a clinician
  • CBC, urine test, blood sugar, or imaging only when clinically needed

Avoid these mistakes

  • Do not use antibiotics, steroid tablets/injections, or strong painkillers without proper medical advice.
  • Do not hide pregnancy, kidney disease, ulcer, allergy, or blood thinner use.
  • Do not delay emergency care when danger signs are present.

Medicine safety and first-aid guide

This section is for patient education only. It does not replace a doctor, pharmacist, or emergency care.

Safe first steps

  • Avoid heavy lifting, sudden bending, and prolonged bed rest.
  • Use comfortable posture and gentle movement as tolerated.
  • Discuss physiotherapy, X-ray, or MRI only when clinically needed.

OTC medicine safety

  • For mild back pain, pain-relief medicine may be discussed with a doctor or pharmacist.
  • Avoid repeated painkiller use if you have kidney disease, stomach ulcer, uncontrolled blood pressure, or are taking blood thinners.

Avoid these mistakes

  • Do not start antibiotics without a proper medical decision.
  • Do not use steroid tablets or injections casually for quick relief.
  • Do not delay emergency care because of home remedies.

Get urgent help if

  • Back pain with leg weakness, numbness around private area, loss of urine/stool control, fever, cancer history, or major injury needs urgent care.
Medicine names, dose, and timing must be decided by a qualified clinician or pharmacist after checking age, pregnancy, allergy, other diseases, and current medicines.

For rural patients and family caregivers

Patient health record and symptom diary

Write your symptoms, medicines already taken, test results, and questions before visiting a doctor. This note stays on your device unless you print or copy it.

Doctor to discuss: Medicine doctor / pediatrician for children / qualified clinician
Tests to discuss with doctor
  • Temperature chart and hydration assessment
  • CBC with platelet count if fever persists or dengue/other infection is possible
  • Urine test, malaria/dengue tests, chest evaluation, or blood culture only when clinically indicated
Questions to ask
  • What is the most likely cause of my symptoms?
  • Which warning signs mean I should go to emergency care?
  • Which tests are really needed now?
  • Which medicines are safe for my age, pregnancy status, allergy, kidney/liver/stomach condition, and current medicines?
  • Do I need antibiotics, or is this more likely viral?

Emergency warning signs such as chest pain, severe breathing difficulty, sudden weakness, confusion, severe dehydration, major injury, or loss of bladder/bowel control need urgent medical care. Do not wait for online information.

Safe pathway to proper treatment

Care roadmap for: Erythematosus Profundus

Use this simple roadmap to understand the next safe steps. It is educational and does not replace examination by a doctor.

Go to emergency care if you notice:
  • Severe or rapidly worsening symptoms
  • Breathing difficulty, chest pain, fainting, confusion, severe weakness, major injury, or severe dehydration
Doctor / service to discuss: Qualified healthcare provider; specialist depends on symptoms and examination.
  1. Step 1

    Check danger signs first

    If danger signs are present, seek emergency care and do not wait for online information.

  2. Step 2

    Record the symptom story

    Write when symptoms started, severity, medicines already taken, allergies, pregnancy status, and test results.

  3. Step 3

    Visit a qualified clinician

    A doctor, nurse, or qualified healthcare provider can examine you and decide which tests or treatment are needed.

  4. Step 4

    Do only useful tests

    Do tests after clinical assessment. Avoid unnecessary tests, random antibiotics, or repeated medicines without diagnosis.

  5. Step 5

    Follow up and return early if worse

    If symptoms worsen, new warning signs appear, or treatment is not helping, return for review quickly.

Rural patient practical tips
  • Take a written symptom diary and all previous prescriptions/test reports.
  • Do not hide medicines already taken, even herbal or over-the-counter medicines.
  • Ask which warning signs mean urgent referral to hospital.

This roadmap is for education. A real diagnosis and treatment plan requires history, examination, and clinical judgment.
