Acquired cystic disease-associated renal cell carcinoma, abbreviated ACD-RCC, is a rare kidney cancer that arises in the context of chronic renal failure.

It was added to the WHO classification of renal neoplasia in the Vancouver modification of 2012/2013.[1]

General

Gross

  • Cysts.

Microscopic

Features:

  • Fused tubular structures/cribriforming/sieve-like architecture.[4]
    • Focal papillary architecture - common.[3]
    • Tumour cells have prominent nucleoli (ISUP nucleolar grade 3) and eosinophilic cytoplasm.
  • Oxylate crystals - important.
  • Acquired cystic disease in background - required.
    • Changes of end-stage kidney (obsolete glomeruli, thyroidization, interstitial fibrosis).

IHC

Features:[2]

  • AMACR +ve.
  • CD10 +ve.
  • Pankeratin +ve.
  • CK7 +ve (heterogeneous).

Others:[2]

  • CD68 -ve.
  • PAX2 -ve.
  • EMA -ve.[6]
  • HMWCK -ve.[6]
