A dramatic case of ibuprofen-induced bullous leukocytoclastic vasculitis (LCV) is described in a patient with a history of prior sensitization to ibuprofen, a common household nonsteroidal anti-inflammatory drug (NSAID) that has few reported adverse skin reactions. Bullous LCV is a relatively rare clinical presentation of LCV, which requires differentiation from other blistering diseases, including bullous erythema multiforme, bullous fixed drug eruption, linear IgA bullous dermatosis, and bullous pemphigoid. The distinctive histopathologic changes of leukocytoclastic vasculitis readily distinguish this bullous eruption from the others.
