Hereditary leiomyomatosis and renal cell carcinoma syndrome-associated renal cell carcinoma is a malignant epithelial tumour of the kidney associated with the hereditary leiomyomatosis and renal cell carcinoma syndrome.

General

  • Often aggressive - significant cause of mortality.[1]

Microscopic

Features - renal cell carcinoma:[1]

  • Large eosinophilic nucleolus with perinucleolar clearing - proposed hallmark - important.
    • May be focal.
  • Variable architecture:
    • Papillary - classic description.
      • Hyaline material within the fibrovascular cores - characteristic.
    • Tubulopapillary.
    • Tubular.
    • Solid.
    • Sieve-like pattern/cribriform.
