Papillary renal cell carcinoma, abbreviated PRCC, PaRCC and papillary RCC, is the second most common type of renal cell carcinoma.

General

  • Historically, PaRCC was subclassified[1] into type 1 and type 2.
    • Type 1 and Type 2 are different on a cytogenetic and molecular basis.[2]

Epidemiology

Gross

  • Renal cortical mass usually >1.5 cm.
  • May be multifocal. ‡
  • Often necrotic appearing - light-to-dark brown, soft/mushy, friable.

Note:

  • ‡ Approximately 10% of PaRCCs are multifocal (based on a set of 5378 patients);[6] it is the renal tumour that is most commonly multifocal.

Microscopic

Features:[7]

  • Cuboidal or low columnar cell in papillae.
  • Interstitial foam cells in vascular cores - key feature.
    • Most sensitive and specific feature of PaRCC.[8]
  • Highly vascular.

Size criterion:

Mnemonic HIP: highly vascular, interstitial foam cells, papillae.

Note:

  • PaRCC - very high mag. (WC/Nephron)

Histological subtyping

Historically, PaRCC was subtyped:[1][14]

  • Type 1 - single layer of cells on basement membrane - most important.
    • Usually low grade nuclear features, i.e. low ISUP nucleolar grade.
    • Other characteristics:
      • Clear cytoplasm.
      • Foamy macrophages - common.
      • Cells smaller.
  • Type 2 - pseudostratification of cells - most important.
    • Usually high grade nuclear features, i.e. high ISUP nucleolar grade.
    • Other characteristics:
      • Eosinophilic cytoplasm.
      • Foamy macrophages - uncommon.
      • Cells larger.

The WHO GU Blue Book 5th Ed. recommends against subtyping.

Another subtype:

  • Oncocytic - oncocytic cytoplasm.
    • Extremely rare ~ a few dozen reported.[15][16]
      • One "large" series was 14 cases.[17]

IHC

Features:[1]

  • AMACR +ve.
  • HMWCK (34betaE12) +ve.
  • Panker (AE1/AE3) +ve.
  • CK7 +ve ~90% of type 1, 20% of type 2.
  • CD10 +ve.[18]

Others:

  • GATA3 +ve - oncocytic variant of PaRCC; negative in other PaRCC subtypes.[19]

Type 1 versus Type 2:[20]

  • CK7:
    • Type 1 ~ 100%.
    • Type 2 ~ 19%.
  • CK19:
    • Type 1 ~ 100%.
    • Type 2 ~ 53%.

Metanephric adenoma vs. PaRCC type 1:[21]

  • AMACR +ve.
  • WT-1 -ve.
  • CD57 -ve.

Molecular

Features:[22]

  • Sporadic: trisomies 7, 16, 17.
  • Familial: trisomy 7.
    • Chromosome 7 = location of MET gene.

Note:

  • Not used for diagnosis.[23]

Sign out

Kidney Tumour, Left, Partial Nephrectomy: 
- PAPILLARY RENAL CELL CARCINOMA. 
-- Surgical margins NEGATIVE. 
-- ISUP nucleolar (Fuhrman) Grade 3. 
-- TNM stage: pT1a pNx. 
-- Please see tumour summary.

Block letters

KIDNEY, RIGHT, RADICAL NEPHRECTOMY:
- PAPILLARY RENAL CELL CARCINOMA, WHO/ISUP NUCLEOLAR GRADE 3, pT2a(2), pNx.
-- SURGICAL MARGINS NEGATIVE.
-- PLEASE SEE TUMOUR SUMMARY.
- RENAL PAPILLARY ADENOMAS.

Micro

The sections show a tumour in the kidney with fibrovascular cores (papillae) that focally contain macrophages. Psammoma bodies are present. Siderophages are present.

The papillae predominantly have a single layer of tumour cells and the cytoplasm of the tumour cells is predominantly clear.

Nucleoli are visible focally with the 10x objective (ISUP nucleolar grade 3).

A second tumour with the same morphology is present and measures 8 millimetres.

Multiple small lesions, like the largest tumour, less than 1.5 cm are present.

Oncocytic variant

KIDNEY, RIGHT, NEPHRECTOMY:
- PAPILLARY RENAL CELL CARCINOMA, ONCOCYTIC -- SEE COMMENT;
- WHO/ISUP GRADE 2;
- SURGICAL MARGINS NEGATIVE;
- PLEASE SEE TUMOUR SUMMARY.

COMMENT:
The oncocytic variant of papillary renal cell carcinoma (RCC) is uncommon and not widely
recognized as a subtype of papillary RCC.  The prognostic significance of the oncocytic 
cytoplasm is uncertain.[1]  The histomorphology in this case is compatible with a type 1 
papillary RCC.
