  A case with granular cell tumor of the cecum was reported. The patient was a 57-year-old man who requested further examination because of his positive fecal occult blood test. A hemispherical protruded lesion in the cecum measuring 16 mm in diameter was disclosed by barium enema. Colonoscopy revealed a smooth-surfaced, hard and yellowish-colored submucosal tumor. It resembled a molar in appearance. Endoscopic polypectomy was performed. Histology with HE staining revealed the presence of eosinophilic granules in the cytoplasm of the tumor cells, and immunochemistry for S-100 protein was positive. According to these results, the diagnosis of granular cell tumor was established . It is uncommon that granular cell tumor in the colon shows a unique appearance as in this case. Histological investigation of our case revealed that this unique appearance is related to its growing process.
