title: [Synchronous prostatic carcinosarcoma: report of 2 cases and review of the literature].
abstract: OBJECTIVE
  Carcinosarcoma of the prostate is a biphasic tumor containing adenocarcinoma and recognisable sarcomatous components. It is a rare neoplasm with less than 40 reported cases. We describe two additional examples showing carcinosarcoma in the initial pathologic material (synchronous presentation).
  
  
  RESULTS
  The patients were 71 and 78 year-old, respectively. The primary prostatic tumour in case one was composed of adenocarcinoma admixed with a neoplastic mesenchymal component that displayed foci of chondrosarcoma, rhabdomyosarcoma and angiosarcoma. The adenocarcinoma in the second case was admixed with spindle cell sarcoma and chondrosarcoma. Both patients died of disease after surgery, 3 and 9 months respectively.
  
  
  CONCLUSIONS
  Synchronous carcinosarcoma of the prostate is a highly malignant neoplasm that may need an aggressive therapy.
