title: Primary immature teratoma of the prostate with angiosarcoma component: its unusual response to chemotherapy.
abstract: Here, we present a case of immature teratoma of prostatic origin, which included an angiosarcoma component. This mass proved unresponsive against preoperative chemotherapy for immature teratoma. Angiosarcoma, although quite rare, should be included in the differential diagnosis as a component of prostatic teratoma, especially in cases in which the tumor proves unresponsive to well-known chemotherapeutic protocols. This is, to our knowledge, the first reported case of primary prostatic immature teratoma containing an angiosarcoma component.
