[Giant schwannoma of musculocutaneous nerve (a case report)]

Abstract

Schwannoma is a tumor that develops from nerve sheath. The authors report an original observation of a giant schwannoma developed in the arm depending on the musculocutaneous nerve. The diagnosis was based on MRI appearance. Confirmation of the diagnosis was made by histological examination. Surgical treatment was resection, taking care preserving adjacent nerve fibers. This allowed recovery without any sequela. Recurrence rate and potential for malignant transformation of this type of tumor is low.
