Renal medullary fibroma, also renomedullary interstitial cell tumour and medullary fibroma, is a benign kidney tumour. It is commonly an incidental finding.^[1]

Symptoms

Renal medullary fibromas are typically asymptomatic.

Renal medullary fibromas are diagnosed by pathologists based on the examination of tissue.

They consist of bland spindle-shaped or stellate-shaped cells in a loose stroma. Renal tubules may be entrapped.

Generally, no treatment is required.
