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

Microscopic

Features:[1]

  • Some features of both:
    1. Clear cell RCC.
      • Clear cells.
    2. Papillary RCC.
      • Pseudopapillae - often do not have true papillae.
  • 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: ‡

DDx:

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.

IHC

Features:[1]

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.

     - CLEAR CELL TUBULOPAPILARY RENAL CELL 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 have a highly favourable clinical behaviour.[1,2]
