title: [Sarcomatoid renal cell carcinoma: 3 case reports].
abstract: We report 3 cases of sarcomatoid renal cell carcinoma, which is an uncommon neoplasm consisting of a typical renal cell carcinoma associated intimately with a sarcomatoid component. All patients were symptomatic at hospitalization and underwent nephrectomy. Two patients died of metastatic renal cancer within a year, and another is alive without evidence of metastasis for 12 months after the surgery. Because sarcomatoid renal cell carcinoma has a highly malignant behavior and poor prognosis, an adjuvant treatment effective in controlling the disease is awaited.
