Flare of Bullous Pemphigoid in Surgically Treated Skin

Bullous pemphigoid (BP) is an acquired, pruritic, blistering eruption of the skin that typically presents as large, tense, subepidermal bullae in elderly persons. In this article, we present the case of an 80-year-old man with a 2-year history of generalized pruritus with occasional bullae in healed incision sites on his abdomen. Results of biopsy and direct immunofluorescence testing demonstrated evidence consistent with BP. This case demonstrated a BP flare in surgically treated skin, a phenomenon that has infrequently been reported in the literature.
