- CLEAR CELL PAPILARY RENAL CELL TUMOUR, preliminary ISUP nucleolar grade 1 of 4, see comment. | |||
Comment: | |||
The tumour has a tubulocystic architecture and is composed of cuboidal cells with clear cytoplasm. The nuclei are reverse stratified. | |||
The tumour stains as follows: | |||
POSITIVE: PAX8 (diffuse), CK7 (strong, diffuse), CK34betaE12 (strong, diffuse), vimentin (diffuse, strong), EMA (moderate, diffuse). | |||
NEGATIVE: CD10. | |||
The findings are in keeping with clear cell tubulopapillary renal cell tumour. These tumours were previously called "clear cell papillary renal cell carcinoma". | |||
These tumours have a highly favourable clinical behaviour.[1,2] | |||

Clear cell papillary renal cell tumour, abbreviated CCPRCT, is a relatively common benign renal tumour.
It was previously known as clear cell papillary renal cell carcinoma, abbreviated CCPRCC
It is also previously known as clear cell tubulopapillary renal cell carcinoma,[1] abbreviated CCTPRCC.
General
- Relatively new entity.
- Shown to be distinct on a molecular basis.[3]
- No vHL gene mutations,[4] seen in clear cell renal cell carcinoma.
- Good prognosis.
- Previously classified as carcinoma.
- Relatively common - if one considers it a RCC: it is the fourth most common type.[7]
- Most common (in order): clear cell RCC, papillary RCC, chromophobe RCC, clear cell papillary RCC.
Microscopic
Features:[1]
- Some features of both:
- Clear cell RCC.
- Clear cells.
- Papillary RCC.
- Pseudopapillae - often do not have true papillae.
- Clear cell RCC.
- Apical nuclei - should be predominant ‡ - key feature.[8]
- In most glandular structures the nuclei are usu. basally located, i.e. in the cytoplasm adjacent to the basement membrane.
- Tubular and/or cystic architecture.
Notes: ‡
- Apical nuclei may be seen focally in clear cell renal cell carcinoma.
- Nuclei should be low grade (ISUP nucleolar grade 1 or 2).
DDx:
- Clear cell renal cell carcinoma - main DDx.
- Papillary renal cell carcinoma.
- Xp11.2 translocation carcinoma.
Note:
- Renal angiomyoadenomatous tumour has been proposed as separate entity.[9] The Vancouver modification of the WHO classification does not consider it a separate entity; it lumps it with clear cell papillary renal cell carcinoma.

Features:[1]
- CK7 +ve - esp. diffuse.[10]
- Usually -ve (or patchy) in clear cell RCC.
- CD10 -ve (0 +ve/9 cases in one series[1]).
- Usually +ve in clear cell RCC.
- Positive in Xp11.2 translocation carcinoma.[11]
- TFE3 -ve.
- By definition +ve in Xp11.2 translocation carcinoma.
- AMACR -ve.[12]
- Usu. +ve in Papillary RCC.
- Smooth muscle actin +ve (focal).[13]
Others:[1]
How to remember: The two key stains are opposite of what the name implies.
- Clear cell RCC: CK7 negative. In this tumour it is the opposite - CK7 is positive.
- Papillary RCC: AMACR positive. In this tumour it is the opposite - AMACR is negative.

Left Kidney Mass, Core Biopsy:
- CLEAR CELL PAPILARY RENAL CELL TUMOUR, preliminary ISUP nucleolar grade 1 of 4, see comment.
Comment:
The tumour has a tubulocystic architecture and is composed of cuboidal cells with clear cytoplasm. The nuclei are reverse stratified.
The tumour stains as follows:
POSITIVE: PAX8 (diffuse), CK7 (strong, diffuse), CK34betaE12 (strong, diffuse), vimentin (diffuse, strong), EMA (moderate, diffuse).
NEGATIVE: CD10.
The findings are in keeping with clear cell tubulopapillary renal cell tumour. These tumours were previously called "clear cell papillary renal cell carcinoma".
These tumours have a highly favourable clinical behaviour.[1,2]
