Acute hemorrhagic edema of infancy (AHEI) is a benign form of leukocytoclastic vasculitis limited to the skin, which occurs in children younger than 2 years of age. The abrupt onset of fever, peripheral edema, and purpuric targetoid plaques in an infant may be confused with other dermatoses such as Henoch-Schönlein purpura, Sweet's syndrome, erythema multiforme, or septic vasculitis. Laboratory studies of patients with AHEI typically show normal results and the disorder follows a benign course with spontaneous resolution occurring in 1 to 3 weeks. We present a case of AHEI occurring in a 7-month-old boy and review the characteristic features of this acute dermatosis.
婴儿急性出血性水肿（AHEI）是一种局限于皮肤的白细胞破碎性血管炎的良性形式，发生于2岁以下儿童。婴儿突然出现发热、外周水肿和紫癜样靶形斑块，可能会与其他皮肤病混淆，如过敏性紫癜、Sweet综合征、多形红斑或感染性血管炎。AHEI患者的实验室检查通常结果正常，该疾病呈良性病程，1至3周内可自发消退。我们报告一例7个月大男孩发生AHEI的病例，并回顾这种急性皮肤病的特征。
