Retroperitoneal schwannoma: Uncommon location of a benign tumor

Mehdi Debaibi et al. Clin Case Rep. .

Abstract

Schwannoma is a type of nerve tumor of the nerve sheath. They are preferentially localized on the head, neck, and flexor surfaces of the extremities. Retroperitoneal schwannoma is extremely rare. The diagnosis is uncommon and based on the anatomopathological and immunochemistry examination of the surgical specimen. We herein report an uncommon location of schwannoma treated with conventional surgery in a 53-year-old female patient admitted to our department for chronic abdominal pain. Retroperitoneal schwannoma is a rare disease that occurs in adult females. The histopathological examination is the only reliable examination for the diagnosis after total surgical resection.

Keywords: neurilemmoma; retroperitoneal schwannoma; retroperitoneal tumors; schwannoma.
