We report a case of metastatic gastric cancer developing from rectal cancer. A 75-yesr-old man undergoing abdominoperineal resection for rectal cancer in July 2005 underwent subsequent adjuvant chemotherapy. Histropathological examination showed signet-ring cell carcinoma, A, ly3, v3, N2, RM1, stage IV. He reported melena in May 2006 and underwent gastrofiberscopy, which showed a submucosal tumor with an ulcer ated top in the middle portion of the stomach. Histologically, the gastric lesion was signet-ring cell carcinoma, the same as the rectal cancer. The tumor was therefore definitively diagnosed as gastric metastasis from rectal cancer.

Key words
