Papillary Adenocarcinomatous Degeneration Occurring in a Multilocular Renal Cyst

Abstract

A multilocular cyst of the kidney in an adult with malignant papillary adenocarcinomatous transformation is described. The histogenesis and prognosis of multilocular cysts are discussed with special reference to their relationship with Wilms' tumour.

Benign multilocular cyst or multilocular cystic nephroma in adults: three case reports

“…The existence of degenerated multilocular cystic nephroma (DMLCN) remains controversial. It would correspond to a MLCN where the epithelial component would focally degenerate into a clear cell or papillary carcinoma [4]. This lesion was defi ned as a MLCN with 1 or 2 foci of malignant cells, less than 5 mm in diameter, and located within the wall of the lesion or within a septation.…”
