. There are several distinct variants that differ in histopathology and, to some extent, in clinical manifestation and genetic susceptibility:

> Clear cell renal cell carcinoma
> Papillary renal cell carcinomas
> Chromophobe renal cell carcinoma
> Multilocular clear cell renal cell carcinoma
> Carcinoma of the collecting ducts of Bellini
> Renal medullary carcinoma
> Acquired cystic disease-associated renal cell carcinoma
> Renal Xp11 translocation carcinoma
> Post-neuroblastoma renal cell carcinoma
> Renal mucinous tubular and spindle cell carcinoma
> Follicualr renal cell carcinoma
> Leiomyomatous renal cell carcinoma

The term renal cell carcinoma, NOS / Unclassified should be used for lesions which histopathologically do not correspond to any of the above variants. They have been estimated to amount to less than 5% of renal cell carcinomas.
