ICD-11 EB41.0 — Bullous pemphigoid

Bullous pemphigoid is the most common autoimmune blistering disease in the Western world. It chiefly affects the elderly and typically presents with a pruritic urticated erythema which evolves into a widespread eruption of intact tense blisters. It can sometimes involve mucous membranes. It is characterised by IgG antibodies to the basement membrane zone, leading to subepidermal clefts that are clinically manifest as blisters.
