Recurrent erythema multiforme-like reaction secondary to recurrent poison ivy exposure.

A 14-year-old boy developed an erythema multiforme-like reaction following Toxicodendron radicans (poison ivy) allergic contact dermatitis three separate times over the course of 3 years. The severity of each erythema multiforme-like reaction corresponded to the severity of the allergic contact dermatitis which preceded it.
