Morphological classification of epithelial renal tumors has been a debatable field since the first description of Grawitz in 1883. In the past WHO has renounced to subvided renal rumors below the level of adenoma and carcinoma. Recent developments in pathology of kidney tumors brought up a new morphological classification which has been adopted in part by the WHO.

Today we can subdivide the most often appearing epithelial kidney tumors into adnomas of the oncocytic-, papaillary-, and metanephric type and carcinomas of the clear cell-, papillary-,
chromophobe-, collecting duct associated-, transitional cell-, neuroendocrine type, and tubulo-mucinous type, although some additional rare and extraordinary types do exist.
