Renal cancer is a heterogeneous group of tumors, the most common of which is the clear cell carcinoma, less common papillary and chromophobe carcinomas. Pathological examination faces difficulties in the differential diagnosis of malignant chromophobe carcinoma and benign oncocytomas, and between types I and II papillary renal carcinoma. However, the precise verification of these types of tumors is required for an adequate prognosis and treatment planning.
