Erythema multiforme after treatment with sorafenib

Abstract

Sorafenib, an oral chemotherapeutic agent used in the treatment of solid tumors, is associated with a variety of adverse cutaneous drug reactions in up to 90% of patients. Infrequently, delayed-type hypersensitivity reactions such as erythema multiforme occur. This case describes a child treated with sorafenib for a retrosternal desmoid tumor who developed widespread erythema multiforme across his extremities, trunk, face, and mucosal membranes.
