Abstract:
Granular cell tumor (GCT) is a relatively rare benign tumor that can be located anywhere throughout the body, but it is uncommon in the gastrointestinal tract, and especially in the colon and rectum. A 41-year-old man visited our hospital with a three-month history of intermittent abdominal discomfort at the left lower quadrant area. Colonoscopic examination revealed a hemispheric, submucosal lesion, about 1.5 x 1.2 cm in size, on the opposite side of the ileocecal valve in the proximal ascending colon. The tumor was removed by an endoscopic snare without any immediate complication. The pathologic findings revealed spindled or polygonal large cells that were positive for S-100, neuron-specific enolase and vimentin, and they were negative for smooth muscle actin and desmin, which was consistent with granular cell tumor. We report here on a case of granular cell tumor of the colon that was successfully treated with endoscopic polypectomy.
