Malignant fibrous histiocytoma of the parotid gland associated with polycythemia.

Although malignant fibrous histiocytoma (MFH) is thought to be the most common soft tissue tumor of late adult life, it is extremely uncommon in the parotid gland. A case of MFH in the parotid is reported, associated with polycythemia, which remitted following surgical extirpation of the tumor.
