Renal Cell Carcinoma, Chromophobe Type “ChRCC”

OLYMPUS DIGITAL CAMERA

Hi there, few days ago i stumbled upon this relatively uncommon renal tumor and misdiagnosed it as Conventional renal cell carcinoma on smears. ” seams i got so much to learn ”

So lets review the Cytological Characteristics of this tumor :

  • polygonal cells.
  • well defined borders.
  • granular to light transparent cytoplasm, clear cells are rare.
  • accentuation of the granularity at the periphery of the cell.
  • central halo giving the cell koilocyte like appearance.
  • the nuclei are eccentric with anisonucleosis.
  • some of the nuclei are condensed with raisinoid appearance.

Beware of the Eosinophilic Variant of Chromophobe RCC as it very hard to differentiate from  Renal Oncocytoma which is a benign tumor.
