Allergic (Henoch-Schonlein) purpura is a nonthrombocytopenic purpura that affects small nonmuscular vessels with involvement of skin, gastrointestinal tract, joint, and kidney. Pancreatitis has rarely been reported as a complication of H-S purpura. In 1965, hemorrhagic pancreatitis as a complication of H-S purpura was reported by Toskin. We experienced one case of pancreatitis complicated with H-S purpura: pancreatic head enlargement was noted in small bowel series and abdominal sonogram with increased serum amylase level (160 U/dL) in a 6-year-old female child who complained of abdominal pain, vomiting, bloody stool, and petechiae on lower extremities.
