A 67-year-old man underwent right hemi-colectomy for ascending colon cancer in 2007. One year later, he was diagnosed as early gastric cancer, and endoscopic submucosal dissection was performed. Pathologically, cancer cells were detected on the vertical margin, so we conducted distal gastrectomy. A dissected lymph node around the hepatic artery was histologically proved to contain adenocarcinoma cells. The cancer cells were positive for CK20. Colon cancer cells were also positive for CK20 but gastric cancer cells were focally positive for CK20. This pattern of CK staining suggested the ascending colon cancer metastasized to a gastric regional lymph node.
