Lingual Schwannoma: A Diagnostic to Remember! A Case Report with Review of Literature

Abstract

Case Report Lingual schwannoma is a benign, slowly growing tumor of Schwann cells of the nerve sheath. 25% of schwannomas are found in the cervicofacial sphere, but only 1-12% in the oral cavity. A tongue is the structure most affected. We report a case of schwannoma of the oral cavity, discuss the different possible differential diagnoses, and specify the interest of the histopathologic exam finished through an immunohistochemical test. Schwannomas clinically represent swelling along the peripheral nerves. Only surgery with histological examination and immunohistochemistry makes the diagnosis possible and can differentiate schwannomas from neurofibromas and other differential diagnoses. Malignant changes in schwannomas are extremely rare.
