Early stage intestinal-type small gastric cancer with lymphatic vessel invasion; report of a case *
We report a case of early stage intestinal-type small gastric cancer with lymphatic vessel invasion. When a 75-year-old man underwent endoscopy during a medical check-up, the endoscopic study showed a slightly reddish lesion on the anterior wall of the antrum. A biopsy specimen of the lesion was diagnosed as Group Ⅴ. The results of an upper GI series, endoscopy, and endoscopic ultrasonography（EUS）lead us to diagnose the lesion as a mucosal gastric cancer. We then performed endoscopic submucosal dissection（ESD）. The pathologic diagnosis showed the tumor to be type 0Ⅱa＋Ⅱc,6×5mm in size, and a moderately differentiated adenocarcinoma（tub2）infiltrating to the submucosal layer. Additional surgical resection showed no lymph node metastasis. (Accepted on March 18，2006)
