Renomedullary_interstitial_cell_tumour, also known as medullary fibroma,[1] is a relatively common benign tumour of the kidney.

General

  • Benign.
  • Common autopsy finding[2] - one review says 26-41% of individuals at autopsy.[3]
    • The commonality is somewhat in dispute.[4]

Gross

  • Small, white well-circumscribed nodule in medulla.
    • Typically less than 3 mm.[3]

Features:[2][5]

  • Small polygonal/stellate cells.
  • Abundant loose/myxoid stroma.
  • +/-Entrapped renal tubules.[6]
