A Case of Henoch-Sch$\\ddot{o}$nlein Purpura after Abdominal Blunt Trauma

Henoch-Schnlein purpura is the most common vasculitis in childhood and shows unique clinical features characteristic purpura, arthritis, abdominal pain, intestinal bleeding, nephritis and so forth by IgA mediated leukocytoclastic vasculitis. The etiology of Henoch-Schnlein purpura is unknown, but many variable causative factors are reported such as infection, drugs, vaccination, food, insect bite and so on. Henoch-Schnlein purpura precipitated by trauma is rare. There have been reports in which Henonch-Schnlein purpura was precipitated by trauma of cranio-face and ankle joint. We experienced a case of Henoch-Schnlein purpura precipitated by abdominal blunt trauma. We report it with a review of the literature. (Korean J Pediatr 2004;47:465-469)
