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.
