Clear cell renal cell carcinoma, abbreviated CCRCC, is the most common type of renal cell carcinoma.
It is also known as conventional renal cell carcinoma (abbreviated CRCC).
General
- Most common subtype of RCC.
- May be associated with Von Hippel-Lindau syndrome.
- Familial clear cell renal cell carcinoma[1] - usually VHL gene mutation.[2]
- VHL gene not mutated in all cases.[3]
Treatment:
- Surgery.
- Various drugs.
- Targeted therapies.
- Tyrosine kinase inhibitors (e.g. sunitinib, sorafenib).[4][5]
- Anti-VEGF antibodies (e.g. bevacizumab).[6]
Gross
Features:
- Golden/yellow colour.
- +/-Haemorrhage (common).
- +/-Necrosis (common in large tumours).
- +/-Calcification.
- +/-Cysts.
- Usually unifocal. ‡
Note:
- ‡ Approximately 4% of CCRCCs are multifocal (based on a set of 5378 patients).[7]
Image
CCRCC. (WC/euthman)
Microscopic
Features:[8]
- Clear cytoplasm.
- May have eosinophilic cytoplasm (in high-grade tumours) - usually focal.
- Delicate branching vasculature - key feature.
- Often called "chicken wire-like" vasculature.
- Solid or trabecular pattern.
- Polygonal cells.
- Central nucleus.
- +/-Rhabdoid cells:
- Eccentric nucleus.
- Abundant eosinophilic cytoplasm.
Notes:
- Cytoplasm may be eosinophilic.[9]
- This change is typically focal - other areas have a classic appearance.
- Chicken wire-like vasculature present - helps distinguish from other tumours.
- Hyaline bodies common.[10]
- Not common in papillary RCC.
- Clear cytoplasm - due to lipid content.
- Necrosis is independent predictor of outcome - if present in a significant quantity:[11]
- >30% is significant for pT3a tumours.
- >20% is significant for pT1-2 pN0 tumours.
DDx:
- Chromophobe renal cell carcinoma.
- Clear cell papillary renal cell carcinoma.
- Xp11.2 translocation carcinoma.
- Adrenocortical carcinoma (ACC)
- EMA -ve, CKs mostly -ve, inhibin +ve (neg. in RCC).[12]
- Alveolar soft part sarcoma.
- Adrenal gland, normal cortex - wispy, vacuolated.
- Epithelioid angiomyolipoma.
- Benign clear cell clusters of the kidney.

Case 1
CCRCC - intermed. mag. (WC)
CCRCC - high mag. (WC)
CCRCC - very high mag. (WC)
Case 2
CCRCC - intermed. mag. (WC)
CCRCC - high mag. (WC)
CCRCC - very high mag. (WC)
Case 3
CRCC - intermed. mag. (WC/Nephron)
CRCC - high mag. (WC/Nephron)
Stains
- Hale's colloidal iron -ve.
- +ve in chromophobe RCC.
Note: Hale's colloidal iron does not stain iron... it stains hemosiderin.[13]
Clear cell vs. chromophobe:
- Chromophobe: "translucent" (NOT quite clear), reticulated, Hale's colloidal iron stain+, CK7+ (cell membrane).
IHC
- CD10 +ve.
- Vimentin +ve.
- CK7 -ve.
- Strong CK7 staining is more in keeping with clear cell papillary renal cell carcinoma[14] or the evolving entity of TCEB1-mutated renal cell carcinoma.
- CK20 -ve.
- Glut-1 >85% of CCRCC (membranous pattern).[15]
- E-cadherin +ve - usually weak, often -ve in higher stage tumours.[16]
- CAIX (also CA9) +ve.
A panel to confirm the diagnosis:
- CK7 (-ve), CD10 (+ve), PAX8 (+ve), vimentin (+ve).
CCRCC versus chromophobe RCC
ISUP recommends:[17]
- CD117 -ve (+ve in ChRCC).
- CA9 (carbonic anhydrase 9) +ve (membranous).[20]
- CK7 -ve (+ve in ChRCC).
May also be useful:
- Vimentin +ve.
- -ve in ChRCC.[19]
CCRCC versus CCPRCC
- CA9 +ve (strong membranous).
- CK7 -ve.
- Usually +ve in clear cell papillary renal cell carcinoma.
- AMACR -ve.
Others:
- CD10 +ve.
- Usually -ve in clear cell papillary renal cell carcinoma.
CCRCC versus Xp11.2 translocation carcinomas
ISUP recommends:[17]
- Cathepsin K -ve.[21]
- TFE3 -ve.
- TFEB -ve.

Biopsy
Kidney Mass, Left, Core Biopsy: - Clear cell renal cell carcinoma - ISUP nucleolar grade 2 (based on biopsy) - No renal parenchyma identified Comment: The quantity of tissue available at microscopy is very limited. Immunostains confirm the morphologic impression (see microscopic).
MDA form
Kidney Mass, Left, Core Biopsy: - CLEAR CELL RENAL CELL CARCINOMA, preliminary ISUP nucleolar grade 2 (see comment). - No renal parenchyma identified. Comment: The quantity of tissue at microscopy is limited, and may not be representative of the lesion identified radiologically.
Resection
Note:
- The surgeon wants the diagnosis and margin status; thus, these are included in the diagnosis line with the tumour stage.

Micro
The sections show a tumour with a chicken wire-like vasculature composed of clear cells with basally stratified nuclei. Hemosiderin-laden macrophages are present. Necrosis is present. Abundant hyaline globules are present.
There is no perinuclear clearing. The cytoplasm is not wispy. Papillae are not evident.
Rare, small nucleoli are visible with the 10x objective. The tumour nuclei are approximately 15 micrometers.
Alternate
The sections show cohesive mildly atypical clear cells with a columnar morphology. Small cystic spaces are present. The nuclei are basal stratified. Nucleoli are not prominent. Siderophages are present. Blood is present.
No perinuclear halos are apparent. No papillary structures are identified. No definite renal parenchyma is seen.
