| A rare subtype of renal cell carcinoma, occurring in the context of end-stage kidney disease and acquired cystic kidney disease, characterized by a usually well circumscribed, solid, multifocal, bilateral tumor with inter or intracellular micro lumen formation (leading to cribiform architecture). Tumors are often diagnosed incidentally in early stages, although complications caused by renal cysts (dull flank or abdominal pain, fever) or renal parenchymal bleeding may mask the underlying neoplastic process. Most have an indolent behavior. |
