Bullous pemphigoid: diagnosis and therapy

Bullous pemphigoid is the most common autoimmune bullous skin disease which occurs more often at higher age. Clinically it presents with tense blisters and eczematous lesions combined with severe pruritus. The pemphigoid-like diseases include mucous membrane pemphigoid, pemphigoid gestationis and linear IgA disease. Diagnosis is based on immunofluorescence microscopy and confirmatory tests (ELISA, immunoblotting). Classical bullous pemphigoid presents with IgG autoantibodies against BP180 and BP230. Treatment includes topical and systemic corticosteroids and adjuvant immunosuppressants.
