Abstract
An unusual case of gastric outlet obstruction due to hypertrophic pyloric stenosis associated with prepyloric ulceration is described. An upper gastrointestinal series showed a tumorous filling defect at the pylorus. Hypertrophy of the muscle layer and tumorous, elevated mucosa were found in the pylorus, and an ulceration was present in the elevated mucosa at surgery. The clinical course was uneventful after selective vagotomy and gastric antrectomy.
