Abstract

Urticaria multiforme (UM) is an allergic hypersensitivity reaction characterized by the acute onset of polycyclic and annular wheals with ecchymotic centers. It is more common in children under 4 years of age, who typically present with a pruritic rash and nontoxic appearance. The diagnosis is clinical. The condition usually has a favorable response to antihistamines and self-limited course. UM is probably underdiagnosed as it is often confused with erythema multiforme and serum sickness-like reaction. Herein is reported a case of UM in a four-year-old boy, followed by a review of the literature on the subject.
