Pemphigus vulgaris is a rare autoimmune disease that causes blistering of the skin and mucous membranes. This guide explains its causes, types, symptoms, diagnosis and treatment. It is for general information only—always consult a qualified healthcare professional for diagnosis and care.
Causes and Triggers
The exact cause is not fully understood, but several factors are believed to contribute:
- Autoimmune dysfunction: the immune system mistakenly attacks desmoglein, a protein that holds skin cells together, leading to blisters.
- Genetic predisposition: certain genetic variations can increase susceptibility.
- Environmental triggers: some medications (such as penicillamine and sulfasalazine), infections, and excess ultraviolet exposure may trigger or worsen it.
- Stress: stressful events may aggravate symptoms or prompt flare-ups.
Types of Pemphigus
- Pemphigus vulgaris: the most common form, with large, fragile blisters on skin and mucous membranes.
- Pemphigus foliaceus: shallow, papery blisters that detach easily, often on the face, scalp and chest.
- Pemphigus vegetans: thick, wart-like lesions in flexural areas such as the armpits and groin.
- Pemphigus erythematosus: red, scaly patches resembling seborrheic dermatitis or lupus.
- IgA pemphigus: smaller, more superficial blisters, often in children and young adults.
Symptoms
The hallmark is fragile blisters that favour the face, scalp, trunk and limbs and often leave painful erosions after bursting. Mucous membranes—mouth, eyes and genitals—are frequently involved. Itching, burning and stinging are common, and fever, fatigue or secondary infection can occur if the skin barrier is compromised.
Diagnosis
Diagnosis combines a medical history and physical examination with targeted tests. A skin biopsy, blood tests for desmoglein antibodies and immunofluorescence studies help confirm the condition. Early, accurate diagnosis by a dermatologist is essential, since other skin conditions can mimic pemphigus.
Treatment Options
There is no cure, but treatment controls symptoms and prevents complications:
- Corticosteroids: topical for milder cases and oral prednisone for moderate to severe disease.
- Immunosuppressants: medicines such as azathioprine or mycophenolate mofetil reduce the steroid dose needed.
- Plasmapheresis and IV immunoglobulin: used for resistant cases to remove or replace harmful antibodies.
- Targeted and supportive care: rituximab, dapsone, gentle wound care and pain management.
Supportive skincare matters too. Gentle products for sensitive skin, a soothing moisturiser or panthenol to support the skin barrier, and daily sunscreen can help keep skin comfortable and reduce flare triggers.
Final Thoughts
Pemphigus vulgaris can significantly affect comfort and quality of life, but with early diagnosis and personalised treatment its symptoms can be managed effectively. Always rely on a qualified healthcare professional for diagnosis and treatment. For dermatology care, book at Skin Clinic, Lahore.
