Hypertrophic Lupus Erythematosus

Hypertrophic lupus erythematosus (HLE) is a rare form of cutaneous lupus erythematosus (CLE) that affects the skin. This condition is characterized by thick, scaly, and erythematous plaques that typically appear on sun-exposed areas of the body such as the face, neck, and hands. Here is a list of definitions and types of HLE, along with further details on each:

1. Discoid lupus erythematosus (DLE)

Discoid lupus erythematosus (DLE) is the most common form of CLE and a type of HLE. It typically presents as circular or oval-shaped lesions on the face, scalp, and ears that can be red, scaly, and sometimes raised. In some cases, these lesions may develop into plaques with a thick, hyperkeratotic (thickened skin) center and a raised, erythematous (red) border. DLE lesions can be painful and itchy and may lead to scarring and hair loss.

2. Hypertrophic lupus erythematosus profundus (HLEP)

Hypertrophic lupus erythematosus profundus (HLEP), also known as lupus panniculitis, is a rare and severe subtype of HLE that affects the deeper layers of the skin and subcutaneous tissue. It typically presents as firm, painless, and erythematous nodules or plaques on the cheeks, ears, scalp, and trunk. These lesions can become ulcerated, and in severe cases, they can cause scarring and disfigurement.

3. Chilblain lupus erythematosus (CHLE)

Chilblain lupus erythematosus (CHLE), also known as perniosis lupus erythematosus, is a subtype of HLE that is associated with cold and damp environments. It typically presents as painful and itchy erythematous plaques and nodules on the hands, feet, nose, and ears. These lesions may be triggered by exposure to cold temperatures and can lead to ulceration and scarring.

4. Lupus erythematosus tumidus (LET)

Lupus erythematosus tumidus (LET) is a rare subtype of HLE that is characterized by non-scarring erythematous plaques on the face, neck, and trunk. These lesions may appear as smooth, non-scaly, and slightly elevated. They typically occur in sun-exposed areas of the body and may be associated with photosensitivity. LET lesions can be mistaken for urticaria or eczema.

5. Hypertrophic lupus erythematosus verrucous (HLEV)

Hypertrophic lupus erythematosus verrucous (HLEV) is a rare subtype of HLE that is characterized by hyperkeratotic, verrucous (wart-like) lesions on the scalp, face, and ears. These lesions may be painful and itchy and can cause hair loss and scarring. HLEV lesions can be mistaken for seborrheic keratosis or viral warts.

6. Bullous lupus erythematosus (BLE)

Bullous lupus erythematosus (BLE) is a rare subtype of HLE that is characterized by the presence of bullae (fluid-filled blisters) on the skin. These lesions can occur on sun-exposed areas of the body and can be painful and itchy. In some cases, BLE can lead to scarring and disfigurement.

Causes

While the exact cause of HLE is not fully understood, there are several factors that are believed to contribute to its development. In this article, we will explore the possible causes of HLE in detail.

1. Genetic factors – Genetic factors are thought to play a role in the development of HLE. Studies have shown that certain genes may be associated with an increased risk of developing the condition.
2. Environmental factors – Exposure to environmental factors, such as ultraviolet (UV) radiation, can trigger HLE in people who are genetically predisposed to the condition.
3. Autoimmune disorders – HLE is an autoimmune disorder, which means that the body’s immune system attacks its own healthy cells and tissues. Other autoimmune disorders, such as rheumatoid arthritis and Sjogren’s syndrome, are also associated with an increased risk of developing HLE.
4. Medications – Certain medications, such as antihypertensives, antimalarials, and nonsteroidal anti-inflammatory drugs (NSAIDs), have been linked to the development of HLE.
5. Hormonal imbalances – Hormonal imbalances, such as those that occur during pregnancy or menopause, can trigger HLE in some people.
6. Infections – Infections, particularly those caused by viruses, have been linked to the development of HLE.
7. Stress – Stress can trigger HLE in some people, although the exact mechanisms behind this are not fully understood.
8. Smoking – Smoking has been shown to be a risk factor for several autoimmune disorders, including lupus. It may also increase the risk of developing HLE.
9. Alcohol consumption – Alcohol consumption has been linked to an increased risk of developing HLE, although the exact mechanisms behind this are not fully understood.
10. Obesity – Obesity is a risk factor for several autoimmune disorders, and may also increase the risk of developing HLE.
11. Chemical exposure – Exposure to certain chemicals, such as solvents and pesticides, has been linked to the development of HLE.
12. Trauma – Trauma to the skin, such as from a burn or injury, can trigger HLE in some people.
13. Chronic inflammation – Chronic inflammation, which can result from a variety of underlying conditions, can increase the risk of developing HLE.
14. UV radiation – Exposure to UV radiation from the sun or tanning beds is a well-known trigger for HLE.
15. Inflammatory bowel disease  – (IBD) IBD, which includes conditions like Crohn’s disease and ulcerative colitis, has been linked to an increased risk of developing HLE.
16. Lupus erythematosus (LE) – LE is a related autoimmune disorder that is also associated with an increased risk of developing HLE.
17. Diabetes – Diabetes has been linked to an increased risk of developing several autoimmune disorders, including HLE.
18. Celiac disease – Celiac disease, a condition in which the immune system attacks the lining of the small intestine in response to gluten, has been linked to an increased risk of developing HLE.
19. Psoriasis – Psoriasis is a chronic skin condition that is characterized by thick, scaly patches on the skin. It has been linked to an increased risk of developing HLE.

Symptoms

Symptoms of HLE in detail.

1. Thickened Skin Lesions

The most prominent symptom of HLE is the presence of thickened skin lesions. These lesions are raised, hard, and often have a scaly texture. They may vary in size and can be found on any part of the body, including the face, arms, legs, and torso.

2. Discoloration

The lesions in HLE may be discolored, ranging from red to purple or brown. The discoloration is often due to the inflammation in the affected areas.

3. Itching

Itching is a common symptom of HLE, and it can be severe in some cases. The itching may be localized to the affected area or may be generalized.

4. Pain

HLE lesions may be painful, especially if they are located on areas of the body that are frequently rubbed or irritated, such as the hands or feet.

5. Sun Sensitivity

People with HLE may be sensitive to sunlight and may develop lesions in areas exposed to the sun. This is due to the fact that ultraviolet radiation can trigger the autoimmune response that causes HLE.

6. Scarring

HLE lesions may cause scarring, especially if they are not treated promptly. The scarring may be permanent and can cause disfigurement in some cases.

7. Hair Loss

Hair loss may occur in areas where HLE lesions are present. This is due to the fact that the inflammation can damage hair follicles, leading to hair loss.

8. Nail Abnormalities

Nail abnormalities may be present in people with HLE. These abnormalities can include ridges, splitting, or discoloration of the nails.

9. Dry Skin

HLE can cause dry skin, especially in areas where the lesions are present. The dry skin may be itchy and flaky.

10. Fatigue

Fatigue is a common symptom of autoimmune diseases, including HLE. People with HLE may experience extreme tiredness and may have difficulty carrying out daily activities.

11. Joint Pain

Joint pain is another common symptom of autoimmune diseases, including HLE. The joint pain may be localized to a specific joint or may be generalized.

12. Swelling

Swelling may occur in the joints or in the areas where HLE lesions are present. The swelling may be mild or severe and can be accompanied by pain.

13. Muscle Weakness

Muscle weakness may occur in people with HLE, especially if the disease is severe. The muscle weakness may make it difficult to carry out daily activities.

14. Fever

Fever may occur in people with HLE, especially during disease flares. The fever may be low-grade or high-grade and may be accompanied by other symptoms such as fatigue and joint pain.

15. Headache

Headache is a common symptom of autoimmune diseases, including HLE. The headache may be mild or severe and may be accompanied by other symptoms such as fatigue and joint pain.

16. Mouth Ulcers

Mouth ulcers may occur in people with HLE. These ulcers can be painful and may make it difficult to eat and drink.

17. Eye Symptoms

Eye symptoms may occur in people with HLE, including dry eyes, redness, and sensitivity to light.

Diagnosis

HLE can be difficult to diagnose and requires a combination of clinical examination, laboratory tests, and skin biopsies. In this article, we will discuss diagnoses and tests for hypertrophic lupus erythematosus and explain their details.

1. Clinical examination: A clinical examination is the first step in the diagnosis of HLE. The dermatologist will examine the skin and look for characteristic features of HLE, such as thick, scaly plaques on sun-exposed areas of the skin.
2. Skin biopsy: A skin biopsy is a procedure where a small sample of skin is taken for examination under a microscope. A skin biopsy is necessary to confirm the diagnosis of HLE. The biopsy will show thickening of the epidermis and dermis, hyperkeratosis, and a dense infiltration of lymphocytes.
3. Direct immunofluorescence: Direct immunofluorescence (DIF) is a test that uses fluorescent dyes to detect the presence of antibodies in skin tissue. DIF can be used to diagnose HLE and will show immunoglobulin and complement deposition at the dermal-epidermal junction.
4. Indirect immunofluorescence: Indirect immunofluorescence (IIF) is a blood test that detects the presence of circulating antibodies in the blood. IIF can be used to diagnose HLE and will show the presence of anti-nuclear antibodies (ANA) and anti-Ro/SSA antibodies.
5. Anti-Ro/SSA antibodies: Anti-Ro/SSA antibodies are a type of antibody that is commonly found in patients with HLE. These antibodies are directed against Ro/SSA proteins, which are found in the skin and other organs.
6. Anti-La/SSB antibodies: Anti-La/SSB antibodies are another type of antibody that is commonly found in patients with HLE. These antibodies are directed against La/SSB proteins, which are also found in the skin and other organs.
7. Complete blood count (CBC): A CBC is a blood test that measures the number of red blood cells, white blood cells, and platelets in the blood. A CBC can be used to monitor disease activity in patients with HLE.
8. Erythrocyte sedimentation rate (ESR): ESR is a blood test that measures the rate at which red blood cells settle to the bottom of a test tube over time. ESR can be used to monitor disease activity in patients with HLE.
9. C-reactive protein (CRP): CRP is a protein that is produced by the liver in response to inflammation. CRP levels can be measured in the blood and can be used to monitor disease activity in patients with HLE.
10. Anti-double-stranded DNA (anti-dsDNA) antibodies: Anti-dsDNA antibodies are a type of antibody that is commonly found in patients with lupus erythematosus. These antibodies can be used to monitor disease activity in patients with HLE.
11. Rheumatoid factor (RF): RF is an antibody that is commonly found in patients with rheumatoid arthritis. RF can also be present in patients with HLE.
12. Antinuclear antibody (ANA) panel: ANA is a type of antibody that is commonly found in patients with autoimmune diseases, including HLE. An ANA panel can detect the presence of ANA and can be used to monitor disease activity in patients with HLE.

Treatment

Different treatments for hypertrophic lupus erythematosus, including medications, lifestyle changes, and alternative therapies. We will provide details about each treatment option and explain how they can help improve the symptoms of HLE.

1. Topical corticosteroids: Topical corticosteroids are creams or ointments that are applied directly to the skin to reduce inflammation and itching. They are a common treatment for HLE and can help reduce the size and redness of the raised plaques.
2. Oral corticosteroids: Oral corticosteroids are prescription medications that are taken orally to reduce inflammation throughout the body. They can be helpful in treating severe cases of HLE but should be used with caution due to potential side effects.
3. Immunosuppressants: Immunosuppressants are medications that work by suppressing the immune system, reducing the inflammation associated with HLE. They are typically used in severe cases of HLE and are often combined with other treatments.
4. Hydroxychloroquine: Hydroxychloroquine is an antimalarial drug that can also be used to treat autoimmune conditions such as HLE. It works by reducing inflammation and can help prevent further damage to the skin.
5. Methotrexate: Methotrexate is a medication commonly used to treat various autoimmune conditions, including HLE. It works by suppressing the immune system and reducing inflammation.
6. Azathioprine: Azathioprine is an immunosuppressant medication that can help reduce inflammation in the skin caused by HLE. It is often used in combination with other treatments.
7. Cyclosporine: Cyclosporine is an immunosuppressant medication that can be used to treat severe cases of HLE. It works by suppressing the immune system and reducing inflammation.
8. Mycophenolate mofetil: Mycophenolate mofetil is an immunosuppressant medication that can help reduce inflammation in the skin caused by HLE. It is often used in combination with other treatments.
9. Dapsone: Dapsone is an antibiotic medication that can be used to treat HLE. It works by reducing inflammation and suppressing the immune system.
10. Thalidomide: Thalidomide is a medication that can help reduce inflammation and prevent further damage to the skin caused by HLE. It is typically used in severe cases of the condition and should be used with caution due to potential side effects.
11. Retinoids: Retinoids are a class of medications that can be used to treat HLE. They work by reducing inflammation and improving skin cell turnover, which can help reduce the size and appearance of raised plaques.
12. Tacrolimus: Tacrolimus is an immunosuppressant medication that can help reduce inflammation in the skin caused by HLE. It is typically used in combination with other treatments.
13. Pimecrolimus: Pimecrolimus is a medication that can help reduce inflammation and itching associated with HLE. It is typically used in mild cases of the condition.
14. UV therapy: UV therapy involves exposing the skin to ultr
