Hereditary leiomyomatosis and renal cell carcinoma syndrome (abbreviated HLRCC), also hereditary leiomyomatosis and renal cell cancer, is an uncommon syndrome caused by fumarate hydratase (FH) gene mutations.[1][2]
Characteristics:
- Hereditary leiomyomatosis and renal cell carcinoma syndrome-associated renal cell carcinoma.
- Benign leiomyomas skin/uterus.
- Uterine leiomyosarcoma.
Formal criteria
The diagnosis of the HLRCC syndrome requires both #1 and #2:[3]
- A pathogenic FH mutation is present by molecular testing.
- One of the following (pathologic) findings:
- Multiple cutaneous leiomyoma where one was proven histologically.
- One cutaneous leiomyoma in the context of a family history of HRLCC.
- RCC with a morphology suggestive of HRLCC syndrome-associated RCC.
General
- Autosomal dominant inheritance[4] with variable penetration.[5]
- In one series of 21 families: 62% had renal cancer, 76% had cutaneous leiomyomas and 100% had uterine leiomyomas.[6]
Features - clinical:
- Leiomyomas - high penetrance.
- Hereditary leiomyomatosis and renal cell carcinoma syndrome-associated renal cell carcinoma.
- Often aggressive and significant cause of mortality.[8]
Note:
- The RCC in the past was typically diagnosed as papillary renal cell carcinoma.[9]
