Laryngeal chondrosarcoma: a 24-year experience at the Royal National Throat, Nose and Ear Hospital.

This paper presents a review of the experience of 12 patients with chondrosarcoma of the larynx treated at The Royal National Throat, Nose and Ear Hospital, London, over the last 24 years. This represents the largest European series and the third largest in the world. Chondrosarcoma is the most frequent non-epithelial malignant tumor of the larynx, with 83.3% of cases arising from the cricoid cartilage in our series. We have shown that deep wedge biopsy with a CO2 laser, aided by computerized tomography scanning, gives the most reliable diagnosis. Laryngeal chondrosarcoma is characterized by indolent growth, a potential for local recurrence and, infrequently, by metastases. The treatment details of our patients are discussed. Adequate partial resection is often successful and use of CO2 laser as the initial treatment in five of these cases is presented.
