Cystic nephroma is a rare, benign 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

Gross

  • Bubble wrap-like appearance.

  • Bubble wrap. (WC)

Microscopic

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.

Images

  • Cystic nephroma - low mag. (WC/Nephron)

  • Cystic nephroma - intermed. mag. (WC/Nephron)

IHC

Features:

  • ER +ve.
  • PR +ve.
  • CD10 +ve.
