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]


Formal criteria

The diagnosis of the HLRCC syndrome requires both #1 and #2:[3]

  1. A pathogenic FH mutation is present by molecular testing.
  2. 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 HLRCC.
    • RCC with a morphology suggestive of HRLCC syndrome-associated RCC.


  • 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]
