Primary malignant fibrous histiocytoma of storiform-pleomorphic type: a case report of an ano-rectal localization.
Among the various localizations of primary malignant histiocytoma, the ano-rectal one is exceedingly rare. In this paper we report a case characterized by a storiform-pleomorphic pattern of the tumor and a rapid fatal course of the disease with metastasis in the lungs. The prognostic value of the histologic features is briefly discussed.
