Association of bullous pemphigoid and dermatitis herpetiformis: a case report

A 21-year-old black man presented itching, symmetric, tense bullae on trunk, extremities and face with residual pigmentation. The histopathological findings included subepidermal bulla and inflammatory infiltrate with eosinophils and neutrophils. On immunofluorescence, a linear pattern of IgG, Ig A and C3 deposition was observed. The patient improved with oral sulfone (100 mg daily). As the case shares clinical, histopathological and immunofluorescence findings of both diseases, it was considered an association of bullous pemphigoid and dermatitis herpetiformis.
