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]

HLRCC is classically described as:[2]

General

  • Autosomal dominant inheritance[3] with variable penetration.[4]

Clinical:

  • Leiomyomas seen in almost all patients.
  • The associated renal cell carcinoma is often aggressive and significant cause of mortality.[5]

Microscopic

Features - renal cell carcinoma:[5]

  • 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.

DDx:

IHC

  • FH -ve.
  • 2SC +ve -- cytoplasmic,[4] cytoplasmic and nuclear.[5]
    • 2SC = S-(2-succino)-cysteine.
