An 80-year-old female was referred to our hospital with anorexia and epigastric discomfort. Endoscopic examination revealed a type Ha tumor in the posterior wall of the gastric antrum. A well-differentiated adenocarcinoma was diagnosed by pathological analysis of the biopsied specimen. En bloc resection of the tumor was achieved by endoscopic submucosal dissection. Histopathological analysis of the resected tissue showed that adenocarcinoma was limited to the mucosal layer. However, intramucosal lymphatic vessel invasion was detected. We describe a case of intramucosal gastric cancer with lymphatic invasion and review the relevant literature.
