Abstract
Renal medullary fibroma, also renomedullary interstitial cell tumour and medullary fibroma, is a benign kidney tumour. It is commonly an incidental finding.
Diagnosis
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.
