A case of subepidermal autoimmune bullous disease with autoantibodies against 200-kDa and 290-kDa antigens

Abstract

Epidermolysis bullosa acquisita (EBA) and anti-p200 pemphigoid are uncommon subepidermal autoimmune bullous diseases caused by autoantibodies against the 200-kDa protein and 290-kDa type VII collagen, respectively. Here we describe a patient with autoantibodies against both 200-kDa and 290-kDa antigens.A 63-year-old-man had itchy tense blisters and edematous erythemas scattered on his trunk, buttocks, extremities and soles (Fig. 1a). There were no ocular or mucosal lesions. Psoriatic skin lesions were not observed. There was no personal or family history of serious diseases.
