Cystic nephroma is a rare kidney tumour.
Turbiner et al.[1] have suggested that cystic nephroma and mixed epithelial and stromal tumour (MEST) are one tumour; the lumping term is renal epithelial and stromal tumour (abbreviated REST).
General
- Rare.
Gross
- Bubble wrap-like appearance.

Features:
- Cysts lined by simple epithelium with hobnailing - key feature.
- Stroma has an ovarian look:
- Blue (basophilic).
- Spindle cells.
Notes:
- Parenchymal elements (e.g. glomueruli, tubules) are not found in the septa between the cysts.
