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:
- Tubular structures with cribriforming/a sieve-like architecture.[2]
- Hobnail cells.
- Oxylate crystals - important.
- Look somewhat like cholesterol clefts.
DDx:
- Acquired cystic renal disease.
- Papillary renal cell carcinoma.
- Hereditary leiomyomatosis renal cell carcinoma syndrome associated renal cell carcinoma.

Features:[1]
