Chondroma of the Larynx

Author and Disclosure Information


THE rarity of chondromata of the larynx is attested by the relatively small number of cases which have been reported. The first comprehensive survey of the world’s literature was made by Irwin Moore1 in 1925. He collected 53 cases which he considered true cartilaginous tumors. The most recent survey (1944) was made by McCall, Dupertuis, and Gardiner,2 who collected an additional 30 cases since Moore’s report. They have summarized each case and have added 2 of their own, making a total of 85 cases. A case reported by Rosedale3 and the one herewith reported bring the total to 87 cases.

The most frequent site of development of chondroma of the larynx is the endolaryngeal surface of the posterior plate of the cricoid cartilage. The next is the thyroid cartilage, then the epiglottis and the arytenoid cartilage. In Rosedale’s case the chondroma arose from the cricoid cartilage, while in ours the tumor had its origin in the left ala of the thyroid cartilage.

Hoarseness and dyspnea are the commonest symptoms, and cough or dysphagia may develop. There may be an external deformity in the neck when the chondroma arises from the thyroid cartilage. The symptoms are caused by obstruction of the airway and interference with the function of the larynx, and they depend upon the location and size of the tumor. Since these tumors usually grow slowly the symptoms increase so gradually that the chondroma may be very large before the patient seeks relief.

The chondroma is usually smooth, rounded, hard,. . .
