Malignant fibrous histiocytomas of the upper respiratory tract are rare, aggressive mesenchymal neoplasms. We report a case of a glottic malignant fibrous histiocytoma of the larynx on a 54 year old man. Only a few have been reported in the English literature. The clinical behaviour and degree of malignancy of these tumours cannot be predicted. Wide, aggressive excision of the tumour with a margin of normal tissue appears to be the treatment of choice. About two years after total laryngectomy the patient is well and free of disease.
