Abstract

Chondrosarcoma is the most frequently encountered nonepithelial tumor of the larynx. Still, laryngeal chondrosarcoma is a rare disease, accounting for less than 1% of all laryngeal neoplasms; only about 600 cases have been reported in the world literature. The two most common sites of origin are the cricoid cartilage (69% of cases) and the thyroid cartilage (9%); arytenoid cartilage origin has been seen in less than 3% of cases. The diagnosis of laryngeal chondrosarcoma is easy to miss because of its infrequent occurrence, its indolent pattern of growth, and the difficulty in differentiating it histopathologically from chondroma. However, suspicion of arytenoid chondrosarcoma may be raised by a finding of its characteristic appearance as a smooth, hard, mucosa-covered supraglottic mass that is fairly recognizable on indirect laryngoscopy. We report a new case of chondrosarcoma of the arytenoid cartilage in a 47-year-old man, and we discuss the clinical features, diagnosis, and management of this uncommon tumor.
