Renal cell carcinoma in the context of HLRCC showing the characteristic hyalinized papillary cores. H&E stain. (WC/Nephron)

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]

HLRCC is classically described as:[3]

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]
