摘要

Introduction: Schwannomas (SNs) are rare tumors derived from Schwann cells. They can occur almost anywhere, but the most common location is cranial nerve VIII where they present as acoustic neuromas. SNs rarely may be located in the GI tract. Case reports of stomach, small intestine, descending colon, and rectal SN exist. An extremely rare site is the ascending colon. Here, we present a case of a 45-year-old man with a diagnosed SN of the ascending colon that was treated successfully via single site laparoscopic right hemicolectomy. Discussion: SNs have been reported to have a wide range of clinical manifestations including intermittent gastrointestinal bleeding, intestinal obstruction, constipation, intussusception, and abdominal pain. The diagnosis is made by histopathological examination demonstrating KIT (CD117) and CD34 stained negative samples and S-100 protein is stained positive. Surgical resection is the mainstay of therapy.
