The first case in which the neurogenic sarcoma and two adenocarcinomas coexisted in the stomach were reported. A 46-year-old woman, who was found to have abnormal findings in the course of gastric mass survey, came to the Detection Center of Hokkaido Cancer Society for detailed examination of the stomach. X-ray and endoscopic examination revealed early gastric cancer (IIc) on the angle and submucosal tumor with central depression on the antrum. Partial gastrectomy was performed at Sapporo Kosei Hospital. The results of microscopic examination were as follows: 1) There were two carcinomas. One on the angle was moderately differentiated adenocarcinoma which was involved the submucosa. The other on the surface mucosa of submucosal tumor was well differentiated adenocarcinoma. 2) The submucosal tumor was neurogenic sarcoma. Immunohistochemical examination for nervous tissue specific S 100 protein was helpful in identifying the tumor as neurogenic origin.
