Colonic metastasis from gastric carcinoma is very rare and usually originated from carcinomas of breast, kidney, prostate and ovary. They generally present as segmental stricture, mimicking granulomatous colitis, polyps, or advanced tumors. There were two cases of metastatic gastric carcinomas of colon reported as multiple polypoid colonic mass. Herein, we reported a case of multiple polypoid colonic metastasis from gastric carcinoma. A 46 year old man presented with symptoms of abdominal distension and hematochezia. After diagnosis of gastric carcinoma, the patient underwent radical total gastrectomy with extranodal radical dissection. One year later, colonoscopy revealed multiple colonic polyps showing metastatic deposits of signet ring cell carcinoma histologically. And it is identical to gastric carcinama histologically which had been resected one year ago. (Korean J Gastrointest Endosc 2000;20:299-302)
