Edema acuto emorragico della prima infanzia
(porpora di Seidlmayer)

Acute hemorrhagic edema is an uncommon leukocytoclastic small-vessel vasculitis that may affect young children. In literature only few cases have been reported (294 cases). In many cases the disease developed after a simple acute infection. The exanthema includes large, round, red to purpuric plaques predominant over the cheeks, ears and extremities and often tender edema of face. Involvement of body systems is rare. The children recover spontaneously without sequelae. We report a case of a 9-month boy, who presented with cockade purpura one week after gastroenteric infection. This is the second case described in our pediatric division in 33 years.
