A 72-year-old female visited our clinic with mild dyspnea and hoarseness. Laryngoscopic examination revealed a mass in the subglottic space and partial paralysis of both vocal cords. A CT scan showed a mass arising from the cricoid cartilage: half of the mass could be visualized. Biopsy under direct laryngoscopy was done, and the pathohistological examination revealed chondrosarcoma of low grade malignancy according to the classification of Lichtenstein and Jaffe. Because the tumor was large, total laryngectomy was performed. Chondrosarcoma of the larynx is an uncommon cartilaginous tumor. Only 13 cases have been reported in Japan since Shibui's description in 1973. The clinical features, pathohistological findings and management of this tumor are discussed, and the literature is reviewed.
