Chondroblastic osteosarcoma of the larynx.

Osteosarcoma of the larynx is a rare lesion. Acceptable cases in the literature are difficult to find. We report a case in which total laryngectomy was carried out for a large, obstructing mass that arose from the cricoid cartilage. We present the histologic criteria for the diagnosis of chondroblastic osteosarcoma.
