A 46-year-old man, who had been ingesting only diet food for five years because of a sense of abdominal fullness after meals, was admitted for hematemesis in July 1994. Under the diagnosis of gastric ulcer and pyloric stenosis due to duodenal ulcer, distal partial gastrectomy was performed. The resected specimen revealed gastric ulcer at the angle of stomach and hypertrophy of the pyloric muscle. Histopathological examination showed neither infiltration of inflammatory cells, fibrosis nor degeneration of Auerbach's nerve plexus in the pylorus. Thus, this case was diagnosed as primary hypertrophic pyloric stenosis, which is rare in adults. If close attention is paid to the characteristic X-ray and endoscopic findings, a precise preoperative diagnosis could be possible.
