Abstract
- Sarcomatoid renal cell carcinoma is uncommon and constitutes approximately 1.0% to 1.5% of all renal parenchymal tumors. Renal tumors that consist of epithelial and sarcomatoid components were called Sarcomatoid renal cell carcinomas. Its distinction from other morphological variants of renal cell carcinoma is significant, because it has been shown to have a much poorer prognosis than the purely epithelial tumors. The diagnosis of sarcomatoid renal cell carcinoma is usually made when epithelial and sarcomatoid components are mixed in nephrectomy specimen. A case of sarcomatoid renal cell carcinoma is herein presented in a 77 year-old women. she complained right flank pain and high fever for 3 days, radical nephrectomy was performed and diagnosis was made by H-E stains and immunohistochemical stains of nephrectomy specimen. A brief review about sarcomatoid renal cell carcinoma is made.
