A 69-year-old woman who underwent laparoscopic assisted distal gastrectomy for early gastric cancer(pathological T1bN1M0)in June 2011was admitted to the hospital because of abdominal pain in May 2015.A n abdominal CT scan showed ileus caused by a transverse colon tumor and ascending colon perforation.We performed emergency right hemicolectomy and diverting ileostomy.The postoperative pathological findings revealed poorly differentiated adenocarcinoma and signetring cell carcinoma similar to the gastric cancer resected 4 years ago.Immunohistochemical findings showed that the colon tumor was positive for CK7, but negative for CK20 and expressed a gastric mucin phenotype.From these findings, the colon tumor was diagnosed as a metastasis from early gastric cancer.Colon metastasis from early gastric cancer is rare and the diagnosis is difficult in some cases.We herein report this case and discuss the clinical and pathologic features of colon metastasis from gastric cancer.
