A man in his 80s underwent examination for arteriosclerosis obliterans of the left common iliac artery in the Department of Cardiac Surgery at our hospital and was referred to our department because mass lesions were found in his stomach upon computed tomography (CT) examination. There were no obvious masses on palpation. Closer examination led to a diagnosis of advanced gastric cancer on the greater curvature of the gastric antrum accompanied by a gastric submucosal tumor on the greater curvature of the gastric angle. Because both lesions were considered resectable, open pyloric gastrectomy, D2 dissection, and a Billroth I procedure were performed. The results of postoperative pathological examination, led to a diagnosis of gastric cancer (pT3N0M0, fStage IIA) concomitant with primary gastrointestinal stromal tumor (GIST) of the stomach (Fletcher classification: low risk). The reported incidence rate of concomitant gastric epithelial tumor and gastric GIST is 0.29%, with only 30 cases reported in Japan. The present case of gastric cancer with primary GIST of the stomach incidentally detected on CT is reported herein along with some comments based on the literature.
