A Case of Granular Cell Tumor of the Larynx
후두의 과립세포종 1례
Abstract
Granular cell tumor or also called Abrikossoff's tumor, is a rare benign tumor that can occur anywhere in the body. Granular cell tumor may single or multiple (synchronous or metachronous). Approximately half of all granular cell tumors occur in the head and neck. most commonly in the tongue. But granular cell tumors of the larynx are rare, accounting for only 7 to 10% of all reported cases. Laryngeal tumors are usually small and men are more frequently affected than women. The exact histogenesis is still not known but most recent data support the neurogenic Schwann cell origin. The preferred treatment is local excision using cold knife or laser. Radiation therapy is of little benefit. We report a case of granular cell tumor of the larynx which was confirmed by histopathology.
