A case of atezolizumab‐induced photodistributed bullous pemphigoid

Abstract

Immunotherapy has revolutionized cancer therapy in recent years but is associated with unique immunologically mediated adverse effects. Immunotherapy‐induced bullous pemphigoid (BP) is an uncommon but established reaction that portends significant management implications as in most instances systemic treatment is required. We report a case of immunotherapy‐associated BP in a marked photodistribution, highlighting the diverse clinical presentations of this eruption.
