title: [A case of benign schwannoma in the ascending colon].
abstract: Schwannomas are rare tumors derived from the cells of Schwann which form the neural sheath. Some patients with gastrointestinal schwannoma have been previously reported in the literature. However, schwannomas of the colon are extremely rare. We herein describe a case of schwannoma of the colon. A 49-year-old woman was admitted with complaint of abdominal pain and investigations revealed the presence of a 4 cm sized mass in the ascending colon. Following right hemicolectomy, histopathology and immunohistochemistry confirmed the colonic lesion to be a benign schwannoma. There was no evidence of specific complication or recurrence until now.
