 Schwannomas of the colon and rectum are uncommon and the indication for laparoscopic resection is not clear. We report a case of schwannoma in the ascending colon which was successfully resected by laparoscopic surgery. A 58-year-old man visited our hospital with a chief complaint of right upper abdominal pain. Gallbladder stones and a tumor, which is 45 mm in diameter, of the ascending colon were detected by ultrasonography and computed tomography. Biopsy specimens of the submcosal tumor could not be obtained under colonoscopic examination. The operation was performed with the preoperative diagnosis of mesenchymal tumor of the ascending colon. In the laparoscopic examination, the capsule of the hard tumor was strong, and the findings of tumor invasion to the surrounding organs were not detected. Laparoscopic right hemicolectomy and colecystectomy were performed. The tumor was diagnosed as benign schwannoma by histopathological and immunohistochemical examination. The diagnosis of colorectal schwannoma is rarely confirmed preoperatively. The laparoscopic findings are helpful in the decision of indication for laparoscopic resection of colorectal mesenchymal tumors, even in a case of schwannoma.
