Acquired cystic disease-associated renal cell carcinoma, abbreviated ACD-RCC, is a rare kidney cancer that arises in the context of chronic renal failure.
General
- Arise in the context of long-standing end-stage renal disease (ESRD).[1]
Gross
- Cysts.
Microscopic
Features:
- Fused tubular structures/cribriforming/sieve-like architecture.[2]
- Focal papillary architecture - common.[3]
- Tumour cells have prominent nucleoli (ISUP nucleolar grade 3) and eosinophilic cytoplasm.
- Oxylate crystals - important.
- Look somewhat like cholesterol clefts.
- Seen easily in polarized light.
- Acquired cystic disease in background - required.
- Changes of end-stage kidney (obsolete glomeruli, thyroidization, interstitial fibrosis).
DDx:
- Acquired cystic disease of the kidney.
- Papillary renal cell carcinoma.
- Hereditary leiomyomatosis renal cell carcinoma syndrome associated renal cell carcinoma.
