[Rare malignant tumors and pseudotumors of the prostate].
The authors presents an updated review of rare malignant tumours of the prostate other than adenocarcinoma, as well as of some diagnostic problems caused by inflammatory pseudotumours. Sarcomas, particularly rhabdomyosarcoma (in childhood) and leiomyosarcoma, represent 0.1 to 0.2% of all prostatic malignant neoplasms. Sarcomas show early local extension and vascular invasion. Treatment consists of combined surgery, chemotherapy and radiotherapy. Other types of even rarer tumours, either primary or metastatic, have also been described in the prostate (carcinoid, malignant melanoma, malignant lymphoma). Finally, some inflammatory and pseudotumours of the prostate (different forms of prostatitis, abcess, infarction) can mimick carcinoma.
