Abstract

Erythema multiforme is a type IV hypersensitivity reaction characterized by acute onset erythematous edematous target like papules and plaques. It has been associated with infections, especially herpes simplex virus, drugs and rarely autoimmune diseases. Unlike other causes, photo-distriubuted idiopathic erythema multiforme develops after exposure to UV and settles in sun-exposed areas. The diagnosis is often based on history, clinical examination, histopathology and phototesting. The management of EM is treating the underlying etiology, sympthomatic topical treatment and antihistaminic drugs.
