Unusual Presentation of Acute Annular Urticaria : A Case Report

الملخص EN

Acute urticarial lesions may display central clearing with ecchymotic or haemorrhagic hue, often misdiagnosed as erythema multiforme, serum-sickness-like reactions, or urticarial vasculitis.

We report a case of acute annular urticaria with unusual presentation occurring in a 20-month-old child to emphasize the distinctive morphologic manifestations in a single disease.

Clinicians who care for children should be able to differentiate acute urticaria from its clinical mimics.

A directed history and physical examination can reliably orientate necessary diagnostic testing and allow for appropriate treatment.
