Fumarate hydratase-deficient renal cell carcinoma (abbreviated FH-deficient RCC) is a formally recognized a distinct entity by the WHO as of 2013.
It was previously known as hereditary leiomyomatosis and renal cell carcinoma syndrome-associated renal cell carcinoma (abbreviated HLRCC syndrome-associated RCC).[1][2]
General
- Often aggressive - significant cause of mortality.[3]
- See hereditary leiomyomatosis and renal cell carcinoma syndrome.
Microscopic
Features - renal cell carcinoma:[3]
- Cells with:
- Large, (usually) eosinophilic, nucleolus with perinucleolar clearing - proposed hallmark - important.
- May be focal.
- Abundant or moderate (eosinophilic/partially clear) cytoplasm.
- Large, (usually) eosinophilic, nucleolus with perinucleolar clearing - proposed hallmark - important.
- Variable architecture:
- Papillary - classic description.
- Hyaline material within the fibrovascular cores - characteristic.
- Tubulopapillary.
- Tubular.
- Solid.
- Sieve-like pattern/cribriform.
- Papillary - classic description.
Notes:
- Not common: psammoma bodies, foamy macrophages.[4]
DDx:
- Papillary renal cell carcinoma.
- Tubulocystic carcinoma of the kidney.
- Collecting duct carcinoma.[5]
- Renal medullary carcinoma - cells also have a prominent nucleolus.

Others:
- CK7 -ve (0 +ve/38 cases[7]).
- CD10 -ve.
- May be positive in clear cell RCC-like areas.
- CK20 -ve (0 +ve/38 cases[7]).
- UEA-1 -ve.[7]
- TFE3 -ve (0 +ve/38 cases[7]).
- CK34betaE12 -ve (0 +ve/38 cases[7]).
