AN UNSUSPECTED DIAGNOSIS FOR A COLONIC NECROTIC MASS
Abstract: schwannomas are benign peripheral nerve sheath tumors derived from Schwann cells which rarely arise in the soft tissues of the gastrointestinal tract. We present a case of a gastrointestinal schwannoma in a previously healthy 50-years-old female, with no family history of congenital diseases. The main symptom of the patients was lower gastrointestinal bleeding. A CT scan and colonoscopy described a 4cm ulcerated polypoid mass in the descending colon. The microscopic morphology of the lesion and the immunohistochemical profile were consistent with a schwannoma. The patient had a favorable evolution after surgical resection.
