Metachronous Colon Metastases from Gastric Adenocarcinoma: A Case Report

The colon is a very rare metastatic localization. Here we report a case of colonic metastases from gastric adenocarcinoma whose clinical presentation was suggestive of a de novo adenocarcinoma of the ascending colon. The authors discuss that in the presence of a previous history of gastric cancer, immunohistochemical analysis on endoscopic biopsies may help in the definition of a differential diagnosis. Furthermore, this rare metastatic localization might suggest a poor prognosis and a more accurate diagnostic work-up.
