Colonoscopy revealed yellowish-white and hard 12 submucosal tumor (SMT) s, a 5-mm SMT in the cecum and 5-mm to 12-mm SMTs in the ascending colon closed to the hepatic flexure to the splenic flexure of the transverse colon. A few SMTs of the transverse colon was performed by biopsy. HE stainng showed acidophilic granules in the cytoplasm. Granules of cytoplasma were strongly positive with imunostaing for S-100 protein. The diagnosis of granular cell tumor was made. Two SMTs of the transverse colon was removed by endoscopic resection.
