Abstract
A seventy three year-old man with hoarseness visited our hospital. A physical examination revealed a pedunculated tumor 5 mm in diameter originating from the posterior margin between the ventricle of the larynx and the right vocal fold of the larynx. The tumor was removed by laryngomicrosurgery. The histopathological findings from the tumor were suggestive of a malignant fibrous histiocytoma.
The literatures were reviewed, and it appears that only 16 cases of such lesions of the larynx have been reported overseas, and that only 8 cases have been reported in Japan. International reports have shown that this tumor tends to recur and to metastasize to distant organs. However, our case has had a good prognosis since the surgery, and most of the other cases in Japan have also had a good prognosis.
