Micrograph showing rhabdoid change in a renal cell carcinoma. H&E stain.

Renal cell carcinoma with rhabdoid morphology is an uncommon finding with a poor prognosis. It is also known as renal cell carcinoma with rhabdoid change.

It should not be confused with renal rhabdoid tumour.

General

Microscopic

Features:

  • Rhabdoid cells:
    • Eccentrically placed large round nuclei with abundant eosinophilic cytoplasm.
    • +/-Very prominent nucleolus.

Notes:

  • May be multinucleated.

Images

  • RCC with RC - low mag.

  • RCC with RC - intermed. mag.

  • RCC with RC - high mag.

  • RCC with RC - very high mag.

  • RCC with RC - very high mag.

IHC

Features:[3]

  • Vimentin +ve (23 of 23 cases).
  • NSE +ve (~80% of cases).
  • S-100 -ve/+ve (+ve ~ 40% of cases).
  • Desmin -ve (23 of 23 cases).
  • SMA -ve (~5% of cases).

MASS, RIGHT KIDNEY, RADICAL NEPHRECTOMY:
- CLEAR CELL RENAL CELL CARCINOMA, ISUP NUCLEOLAR GRADE 4, pT1b, pNX.
-- RHABDOID CHANGE PRESENT, SEE COMMENT.
-- MARGINS NEGATIVE FOR MALIGNANCY.
-- PLEASE SEE TUMOUR SUMMARY.

COMMENT:
Rhabdoid change is considered by some to be analogous to sarcomatoid 
change.[1]  The rhabdoid change in this case represents approximately 
35% of the tumour, and has ISUP nucleolar grade 4 nuclear features.
