Abstract
Many tumours of the kidney have pink cells with abundant eosinophilic cytoplasm. Among these tumours, those arising from renal epithelium (Pink cell renal epithelial tumours) that include:
1. Renal cell carcinoma, clear cell type, eosinophilic variant.
2. Renal cell carcinoma, papillary type, eosinophilic variant.
3. Renal cell carcinoma, chromophobe type, eosinophilic variant.
4. Oncocytoma.
5. Collecting duct carcinoma.
The old classification of RCC (clear, granular and mixed) failed to provide good clinicopathologic correlation, moreover a subtype of renal neoplasms with granular cell features, was described, the so-called renal oncocytoma, which appeared to have an excellent prognosis. The Mainz classification is now widely accepted because it is based on conventional histopathologic
