COMMENT: | |||
The oncocytic variant of papillary renal cell carcinoma (RCC) is uncommon and not widely | |||
recognized as subtype of papillary RCC. The prognostic significance of the oncocytic | |||
cytoplasm is uncertain.[1] The histomorphology in this case is compatible with a type 1 | |||
papillary RCC. | |||
