A resected colorectal cancer patient presented with a submucosal tumor and synchronous isolated stomach metastasis. The patient, a 35-year-old female, developed abdominal pain and anorexia due to an ileus. On colonoscopy a submucosal-like tumor was found in the ascending colon. On gastroscopy, a submucosal tumor in the pyloric part of the stomach was noted. A right hemicolectomy and distal gastrectomy were done. The colonic tumor was 40×25mm in size and was covered with villus mucosa ; the gastric submucosal tumor was 45×35mm in size. Microscopically, the colonic tumor, which was primarily covered in submucosal tissue was diagnosed as a well differentiated adenocarcinoma ; the gastric tumor was similar to the colonic tumor. The patient has been well for 19 months ; no recurrences have been noted. Colorectal cancer presenting as a submucosal tumor is rare. Among the 21 reported Japanese cases of gastric metastasis from colorectal cancer 11 were resected ; only 2 cases did not have a recurrence after more than 1 year. Resection should be considered in patients with metastasis.
