Furosemide-induced bullous pemphigoid: case report and review of literature.

Bullous pemphigoid (BP) is an acquired autoimmune disease characterized by subepidermal vesicles and bullae. The etiology for BP is mostly idiopathic with the highest occurrence in elderly patients; however, it is now well-accepted that BP has been triggered by or associated with drug therapy. We present a case of furosemide-induced bullous pemphigoid and review the literature of drug-induced bullous pemphigoid (DIBP).
