SCHWANNOMA OF THE NASAL SEPTUM: A RARE CASE

Schwannomas are benign tumors originated in the neural crests derived from Schwann cells. It is rarely seen in the nose and paranasal sinuses, and it very rarely originates from the nasal septum. We report the case of a 56 year-old male admitted to the Department of Otolaryngology - Head and Neck Surgery at Avicenna Military Hospital in Marrakesh (Morocco), with the complaint of a progressive left nasal obstruction since the last 9 months. Local examination and rigid endoscopy showed a smooth polypoid lesion completely filling the left nasal fossa, with a pedicle in the posterior septum region. Contrast enhanced computed tomography and magnetic resonance imaging suggested a benign origin. The tumor was completely removed via an endoscopic approach and histopathologic examination revealed a schwannoma.
