Acute hemorrhagic edema in an infant mimicking Henoch-Schonlein purpura: a case study / 소아과

ABSTRACT

Acute hemorrhagic edema of infancy (AHEI) is an uncommon form of cutaneous leukocytoclastic vasculitis that occurs in infants and children younger than 2 years. AHEI is characterized clinically by marked peripheral edema and fever as well as large palpable purpuric and ecchymotic skin lesions in a target-like pattern, mainly on the face, ears and extremities, similar to the skin findings of Henoch-Schonlein purpura (HSP). The skin lesions heal spontaneously within one to three weeks and internal organs are rarely affected. We report a case of AHEI occurring in a 23-month-old boy who was initially misdiagnosed as HSP, and was later diagnosed according to his clinical symptoms and histochemical characteristics.
