Summary

Metastases to the colon are rare and a high-frequency primary region is the stomach. In cases of metastases to the colon, the morphological type of the metastatic region is mostly the infiltrating type of poorly differentiated or undifferentiated adenocarcinoma with lymph and blood vessel invasion. A case of cancer metastasis to the transverse colon that originated from advanced gastric cancer, which shows the difficulties in the precise diagnosis of metastases to the colon, is presented. In the present case, the gastric carcinoma was determined to be an advanced infiltrative ulcerative adenocarcinoma and the colon carcinoma was determined to be a superficial depressed adenocarcinoma. After surgery, the colon carcinoma was diagnosed as a metastatic adenocarcinoma from gastric adenocarcinoma with high invasion of vessels, by immunohistopathological analysis of CK7, CK20, p53 and HER-2. In this report, previously reported cases of metastases to the colon from gastric cancer were reviewed and their morphological characteristics were analyzed.
