A rare case of malignant fibrous histiocytoma (pleomorphic undifferentiated sarcoma NOS) of the vocal fold.

Malignant fibrous histiocytoma, also known as pleomorphic undifferentiated sarcoma not otherwise specified, arises in numerous organs. The first-line treatment is complete excision of the mass, but in some cases postoperative chemo- and/or radiotherapy is recommended. Only a few cases of malignant fibrous histiocytoma of the vocal fold have been previously reported in the literature. We report a new case, which originated in the true vocal fold of a 65-year-old man. The mass was removed via CO2 laser excision with preservation of the vocal fold and without the need for further treatment. At 3 years of follow-up, the patient remained recurrence-free.
