Mucha-Habermann disease may also be called PLEVA (pityriasis lichenoides et varioliformisacuta). It is a skin disease characterized by a recurrent red rash that is itchy and burning. There are red elevated areas on the skin, with small pus, lymph, or serous-filled blister-like elevations. There also may be headache, chills, malaise, and sometime pain in one or more joints. It affects females and males equally.
Pityriasis lichenoides et varioliformis acuta (PLEVA) is the acute form of an inflammatory skin condition called pityriasis lichenoides. People with PLEVA may develop a few to more than one hundred scaling papules which may become filled with blood and/or pus, or erode into crusted red-brown spots. Papules may itch or burn, and some people may experience fever or joint pain. Although PLEVA may occur at any age (including infancy), it most commonly affects children and young adults. A skin biopsy is needed to confirm the diagnosis. The exact underlying cause is unknown, but some scientists suspect that it may occur due to an exaggerated immune response to an infection or an overproduction of certain white blood cells (a lymphoproliferative disorder). If treatment is necessary, recommended therapies may include oral antibiotics, sun exposure, topical steroids, immunomodulators (medications used to help regulate or normalize the immune system), phototherapy and/or systemic steroids. PLEVA may last for a few weeks to years, and may fluctuate between getting better and worse before going away on its own.[1][2][3][4]
Types of Mucha-Habermann Disease
- Pityriasis Lichenoides et Varioliformis Acuta (PLEVA): The most common form of Mucha-Habermann Disease, causing red, scaly skin lesions that may resemble chickenpox.
- Pityriasis Lichenoides Chronica (PLC): A less severe and more long-lasting form, characterized by persistent, milder skin rashes.
Causes of Mucha-Habermann Disease
- Unknown Origin: The exact cause remains a mystery, but it is not contagious.
- Infections: Some cases may be triggered by viral or bacterial infections.
- Immune System: An overactive immune system may play a role.
- Genetics: There may be a genetic predisposition in some individuals.
- Medications: Rarely, certain medications can be associated with the disease.
- Stress: Stress may exacerbate the condition in some cases.
- Environmental Factors: Environmental factors could potentially influence the development of the disease.
- Hormonal Changes: Hormonal changes, such as during puberty, might be a factor.
- Autoimmune Response: The body’s immune system may mistakenly attack the skin.
- Vaccination: Some cases have been reported following vaccination.
- Food Allergies: Food allergies have been suggested as a possible trigger.
- Sunlight Exposure: Excessive sunlight may worsen symptoms.
- Inflammatory Disorders: Coexistence with other inflammatory conditions is possible.
- Toxins: Exposure to certain toxins might contribute.
- Skin Trauma: Skin injuries or surgeries may sometimes precede the disease.
- Insect Bites: Rarely, insect bites have been associated with onset.
- Pregnancy: Some women develop the disease during pregnancy.
- Allergies: Allergic reactions may be linked in some cases.
- Immune Disorders: Underlying immune disorders can increase the risk.
- Heredity: There may be a genetic component in some families.
Symptoms of Mucha-Habermann Disease
- Skin Lesions: Red or pinkish bumps or spots on the skin.
- Itching: Intense itching often accompanies the lesions.
- Blisters: Fluid-filled blisters or pustules may form.
- Scaling: Skin may peel or flake.
- Ulceration: Severe cases may lead to open sores.
- Fever: Occasionally, fever may occur.
- Fatigue: Some individuals experience tiredness.
- Joint Pain: Joint pain can be a rare symptom.
- Enlarged Lymph Nodes: Swollen lymph nodes near affected areas.

- Depression: Some individuals may experience depression.
- Difficulty Sleeping: Skin discomfort can disrupt sleep.
Diagnostic Tests
- Physical Examination: A dermatologist will examine your skin lesions.

- Imaging: Rarely, imaging tests may be done in severe cases.
- Lymph Node Biopsy: If lymph nodes are enlarged.
- Histopathology: In-depth examination of skin tissue.
- Tzanck Smear: To rule out herpes or other viral infections.
- PCR Testing: Detects viral DNA in some cases.
- Skin Allergy Testing: Identifies potential triggers.
- Direct Immunofluorescence: Detects antibodies in skin tissue.
- Skin Culture: To detect bacteria or viruses.
- Complete Blood Count (CBC): To check for abnormalities.
- Skin Prick Testing: For allergies.
- Rheumatologic Tests: To assess joint involvement.
- CT Scan: Rarely used but may show internal involvement.
- Skin Examination with Wood’s Lamp: Helps distinguish certain skin conditions.
