KIDNEY (LESION), LEFT, CORE BIOPSY:
- RENAL PARENCHYMA.
- NEGATIVE FOR MASS LESION, SEE COMMENT.
 
COMMENT:
No mass lesion is apparent in the tissue sampled. A re-biopsy should be considered.
 
Renal parenchyma:
- Glomeruli: seven glomeruli sampled, no apparent glomerular pathology on the H&E sections.
- Interstitium: interstitial fibrosis is not identified.
- Tubules: no pathology is apparent.
- Vessels: mild atherosclerosis, no hyalinization of arterioles apparent.

===Molecular===
Recurrent molecular changes in RCC:
*Clear cell RCC:
**Loss of 3p - contains the VHL gene.
*Papillary RCC:
**Sporadic:
***Trisomy 7, 16, 17.
***Loss of Y.
**Familial:
***Trisomy 7 - contains MET gene.<ref>{{OMIM|164860}}</ref>
