Penfigoide buloso con eritema figurado. Informe de un caso.

Bullous pemphigoid is an autoimmune dermatosis characterized by deposition of immunoglobulin G (IgG) and/or complement along basement membrane zone. The lesions of bullous pemphigoid are tense blisters on trunk and extremities, oral lesions are unusual. Figurate erythema includes some dermatologic pictures characterized by annular and polycyclic lesions. Figurate erythema can be confused with erythema gyratum repens, dermatosis associated statistically to malignant neoplasias. The objective for reporting this case is to inform the simultaneous association between bullous pemphigoid and figurate erythema in 83 year old man without underlying malignancy.
