Abstract
A 68-year-old male was admitted to our hospital because of gastric cancer. Gastrointestinal endoscopy revealed a Borrmann type 3 tumor at the lesser curvature of the lower body of the stomach. A biopsy specimen of the gastric lesion disclosed moderately differentiated adenocarcinoma. Preoperative computed tomography showed no metastasis to any other organs. Distal gastrectomy was performed. During the operation, a tumor embolus in the left gastric vein was recognized. It was exposed to the portal vein trunk, and it had not invaded to the portal vein wall, as determined by intraoperative ultrasonography. Therefore, an additional tumor embolectomy was performed. The main tumor lesion and the tumor embolus and lymph nodes were histologically diagnosed a hepatoid adenocarcinoma of the stomach. The postoperative course was uneventful, and the hepatoid adenocarcinoma has not recurred for three years and three months after the surgery．
