Hereditary leiomyomatosis and renal cell carcinoma (abbreviated HLRCC), also hereditary leiomyomatosis and renal cell cancer, is an uncommon syndrome caused by fumarate hydratase (FH) gene mutations.[1][2]
HLRCC is classically described as:[3]
- Papillary renal cell carcinoma type 2.
- Benign leiomyomas skin/uterus.
- Uterine leiomyosarcoma.
General
- Autosomal dominant inheritance[4] with variable penetration.[5]
- In one series of 21 families: 62% renal cancer, 76% had cutaneous leiomyomas and 100% had uterine leiomyomas.[6]
Clinical:
- Leiomyomas seen in many patients.
- The associated renal cell carcinoma is often aggressive and significant cause of mortality.[8]
Microscopic
Features - renal cell carcinoma:[8]
- Large eosinophilic nucleolus with perinucleolar clearing - proposed hallmark - important.
- May be focal.
- Variable architecture:
- Papillary - classic description.
- Hyaline material within the fibrovascular cores.
- Tubulopapillary.
- Tubular.
- Solid.
- Sieve-like pattern/cribriform.
- Papillary - classic description.
Notes:
- Not common: psammoma bodies, foamy macrophages.[9]
DDx:
- Papillary renal cell carcinoma (type 2).
- Tubulocystic carcinoma of the kidney.
- Collecting duct carcinoma.[6]
- Renal medullary carcinoma - cells also have a prominent nucleolus.

IHC
- Fumarate hydratase (FH) -ve.
- 2SC +ve -- cytoplasmic,[5] cytoplasmic and nuclear.[8]
- 2SC = S-(2-succino)-cysteine.
Others:
- CK7 -ve (0 +ve/38 cases[4]).
- CD10 -ve.
- May be positive in clear cell RCC-like areas.
- CK20 -ve (0 +ve/38 cases[4]).
- UEA-1 -ve.[4]
- TFE3 -ve (0 +ve/38 cases[4]).
- CK34betaE12 -ve (0 +ve/38 cases[4]).
