ABSTRACT: 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.
