Henoch-Schönlein purpura (HSP) is an acute small vessel vasculitis. It is the most common vasculitis in children, with an annual incidence of about 10 cases per 100.000 children. Although gastrointestinal manifestations are common, gastric outlet obstruction is never reported. The authors present the case of a 13-y-old boy having coffee ground vomitus, melenic stools and pyloric stenosis. Improvement of symptoms was achieved by conservative management with steroid therapy and gastric decompression.
