Abstract
We describe herein a rare case of metastatic colon cancer diagnosed 15 years after gastrectomy. The patient was a 62-year-old man with diarrhoea and abdominal pain as his major symptoms, who had undergone a total gastrectomy for gastric signet ring cell carcinoma 15 years previously. Colonoscopic examination showed two-thirds circumferential stenosis caused by a submucosal tumor in the descending colon and circumferential stenosis with irregular and nodular mucosa in the rectum. Histological examination revealed signet ring cell carcinoma. The cancerous lesion was finally diagnosed to be metastatic colon cancer traced back to the gastric cancer by immunohistological investigations. He was diagnosed as having inoperable colon cancer with multiple stenoses and was treated with TS-1.
