A 57-year old man had a left anterior neck tumor, and another small tumor was found in the laryngeal ventricle by indirect laryngoscopy. A CT scan showed a well-circumscribed tumor growing from the thyroid lamina into the paraglottic space. Under general anesthesia the tumor was dissected with fenestration of the thyroid ala without any complications, such as hoarseness or deformity. In Japan 35 cases of cartilagenous tumors arising in the laryngeal cartilage have been reported, including our case. In six of these 35 cases the tumor was in the thyroid cartilage. Both chondrosarcoma and chondroma are often seen in the thyroid cartilage, whereas chondroma is seen more frequently than chondrosarcoma in the cricoid carilage.
