Abstract
Granular cell tumors of the larynx are uncommon lesions. Only 15 were identified at the Columbia-Presbyterian Medical Center, New York, during the past 45 years. These tumors produce hoarseness usually and are identified as small keratotic, polypoid, or sessile nodules involving the glottic region (most often posterior glottis, arytenoid, or vocal process). These lesions can usually satisfactorily be treated by endoscopic excision. On histologic examination, pseudoepitheliomatous hyperplasia is frequently seen and may be misinterpreted as squamous cell carcinoma.
