Abstract

Firbous histiocytomas are soft tissue tumors of histiocytic orgin. One percent prove to be malignant. Reliable histologic criteria of malignancy are few, if any, and the diagnosis of malignancy often must be made on clinical (metastases) rather than histologic fround. Thirty-five cases originating in various deep structures of the head and neck, excluding the orbit, have been reported in the literature since 1972. One additiona case, a malignant tumor of the submandibula gland, is added herewith. Recurrence following initial surgery has been common and stems from inadequate exicision of the primary lesion. Microschpic spread of this tumore from its primary site calls for radical rather than conservative surgical excision, At present, radiotherapy and chemotherapy appear to be of little value in the treatment of these tumors.
