Malignant fibrous histiocytoma of the mandible.

Malignant fibrous histiocytoma of the mandible has appeared frequently enough in the world literature in recent years to assume a legitimate place in the differential diagnosis of neoplastic masses of the lower jaw. This article reports a pertinent case and tabulates and correlates the findings of all cases reported thus far. The report also explores the contribution of immunohistochemistry to proper diagnosis and emphasizes the advantages of a cojoint effort between surgeon and pathologist at the time of initial patient evaluation. The case reported also demonstrates the poor prognostic characteristics of this lesion and the uncertainty as to proper mode of treatment.
