title: [Leiomyosarcoma and liposarcoma: rare tumors of the kidney].
abstract: Sarcoma accounts for 2.8% of all renal tumours. We report a case of renal leiomyosarcoma (T2 N0 M0) and a case of renal liposarcoma (T3 N0 M0) submitted to surgery and chemo- and radiotherapy. Follow-up at nine months and 4 years, respectively, revealed the patients are tumor-free. The literature is reviewed highlighting the beneficial effect of chemo- and radiotherapy combined with surgery in the treatment of these tumors with a poor prognosis per se.
