Facial edema as the initial presentation of Henoch-Schonlein purpura in a 5-year-old boy.

The appearance of nonthrombocytic purpura is an important clue for the diagnosis of Henoch-Schonlein purpura (HSP). However, this classic skin lesion may be preceded by other symptoms such as abdominal pain and arthralgia, and the diagnosis may be delayed. Facial edema as a manifestation of HSP is typically observed in children younger than 2 years. We report a 5-year-old boy with facial edema at presentation; until 3 days later, the boy returned because of abdominal complication (intussusception) and developed purpura, the diagnosis of HSP was established.
