Renal cell carcinoma with fibromyomatous stroma, abbreviated RCC FMS, is an evolving subtype of renal cell carcinoma.[1]
Microscopic
Features:
- Fibromyomatous stroma - key feature.
DDx:
- Clear cell renal cell carcinoma.
- ELOC-mutated renal cell carcinoma.
- Clear cell papillary renal cell tumour.
IHC

| Clear cell papillary renal cell tumour | +ve (diffuse) | -ve | +ve | -ve[2] |
