A Esophagogastroduodenoscopy findings during the preoperative examination for gastric submucosal tumors. An elevated lesion, 8 mm in size, with depression in the center, covered with normal mucosa was observed in the anterior wall of the antrum. B Upper gastrointestinal series findings. A raised lesion with a central depression, 8 mm in size, was found in the greater curvature of the gastric body (arrow). C Endoscopic ultrasonography findings. A 10-mm tumor was found in the second layer (arrow). Because of the thinning of the third layer, submucosal invasion could not be completely ruled out (arrow head)
