Henoch Schönlein purpura presenting as duodenal ulcer and gastric outlet obstruction.

Henoch-Schönlein purpura (HSP) is an acute small vessel leucocytoclastic vasculitis. It is the commonest vasculitis in children, with an incidence of about 10 cases per 100, 000 a year. Gastrointestinal manifestations are commonly encountered, however hematemesis and gastric outlet obstruction are rarely reported. The authors present the case of a 5-y-old boy having hematemesis, gastric outlet obstruction and multiple duodenal ulcers. He improved with steroids and conservative management.
