THE FREQUENCY of sarcoma of the larynx based on cases reported during the past two decades would indicate that it is uncommon, although earlier writers believed that it formed about 10 per cent of malignant neoplasms. In Havens and Parkhill's1 studies of laryngeal tumors observed at the Mayo Clinic for a period of thirty years, the ratio of sarcoma to carcinoma was 1 to 100.
