Sarcomatoid chromophobe renal cell carcinoma: A rare entity with prognostic significance.

Renal cell carcinoma (RCC) is the most common malignancy of the kidney and has multiple subtypes. The sarcomatoid variety is considered a form of dedifferentiated carcinoma. It is more commonly associated with clear cell variant but very few are associated with chromophobe RCC. When present, it is associated with a significant decrease in patient survival due to its rapid growth and intrusive behavior. Here, we report a unique case of sarcomatoid chromophobe RCC in a 35-year- old woman.
