A Case of Glossopharyngeal Schwannoma Protruding to the Larynx: A Case Report

ABSTRACT

Schwannoma is benign tumor that can occur in any part of the nerve that contains a Schwann cell. It is rare in the head and neck region and is characterized by common postoperative neurologic symptoms. We experienced a cervical schwannoma in a 22-year-old young man. Except for a foreign body sensation in the neck and a mass in the anterior region, there were no other complaints. A retropharyngeal schwannoma was most suspected considering neck computed tomography, magnetic resonance imaging, laryngoscopy and fine needle aspiration. Surgical treatment was performed, and the origin of the schwannoma was diagnosed as the tonsillar branch of the glossopharyngeal nerve. Histopathological examination confirmed the presence of a schwannoma with typical characteristics. After surgery, the patient recovered without any side effects. We report this case with a review of the literature.
