Primary pure intratesticular fibrosarcoma

Testicular sarcoma appears to be a rare stromal tumor usually of indolent c ourse with potential for distant metastases. A pure primary intratesticular fibrosarcoma in a 71-year-old male is presented. By the time the tumor bec ame evident metastases had already occurred widely. The course was rapidly fatal. A review of the literature yielded only one case reported previously . The present case illustrates that pure fibrosarcoma occurs occasionally a s a stromal tumor and may be associated with a dismal prognosis. The diagno sis of pure fibrosarcoma should be made only after extensive sampling of th e testicular tumor to rule out an associated germ cell component. The diffe rential diagnosis also includes the fibroma of gonadal stroma origin and th e unclassified sex cord-stromal tumor with a predominance of spindle cells.
