E, Chromophobe renal cell carcinoma
can rarely have focally papillary component with typical chromophobe renal cell carcinoma
Among them, renal oncocytoma and chromophobe renal cell carcinoma
(RCC) originate from intercalated cells in the collecting duct and share some morphologic, histologic, electron microscopy findings, and immunohistochemical characteristics (2, 3).
MicroRNA expression profiles predict clinical phenotypes and prognosis in chromophobe renal cell carcinoma
. Sci Rep 2015;5:10328.
Unfortunately, most oncocytomas are difficult to differentiate from chromophobe renal cell carcinoma
due to overlapping ultrastructural, immunohistochemical, and morphological characteristics .
However, the differentiation between the benign oncocytoma  and its malignant counterpart, the chromophobe renal cell carcinoma
, is a continuous challenge for all diagnostic disciplines, such as radiology, urology, and pathology, since there are no absolute distinctive diagnostic criteria.

(3) Often times it is difficult to histologically distinguish clear-cell renal cell carcinoma from chromophobe renal cell carcinoma
and having the difference in the levels of CB1 receptor, i.e., down-regulated in clear-cell renal cell carcinoma while maintaining normal levels in chromophobe, could serve as an important diagnostic tool to differentiate between the two.

Chromophobe renal cell carcinoma
(ChRCC) is a variant of parenchymal renal cell carcinoma, comprising 2-5% of all renal cell carcinoma and characterised by unique morphological, histochemical, ultrastructural and genetic features (1-5).
