Abstract

Urticaria multiforme (UM), a relatively new defined disease, is a morphological subtype of urticaria seen in infants and young children, characterised by acute onset of annular or polycyclic wheals with dusky centres in fleeting duration, associated with acral oedema. We report a case of UM in a neonate diagnosed clinically, emphasizing the distinctive dermatologic manifestations of the disease.

多形性蕁麻疹（UM）是一種相對較新定義的疾病，見於嬰幼兒，是蕁麻疹的一個形態學亞型，其特徵性表現是急性一過性環形或多環狀風團，皮疹中心色暗，且伴有肢端水腫，我們報導一例臨床診斷為UM的新生兒病例，目的是強調這種疾病獨特的皮膚表現。
