Photoletter to the editor: Psoriatic erythroderma associated with bullous pemphigoid: clinical appearance and histopathology.

Abstract

Psoriasis and bullous pemphigoid represent two clinically well-characterized, chronic, inflammatory skin conditions. The concomitant occurrence of these two entities in a patient is rare. We report a 62-year-old male with personal history of psoriasis vulgaris who developed disseminated bullous pemphigoid associated with psoriatic erythroderma. Skin histopathology from a scaly plaque was consistent with the diagnosis of psoriasis and showed subepidermal blister with inflammatory infiltrate of eosinophils with some neutrophils.
