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]
It is characterized by:[2]
- Papillary renal cell carcinoma type 2.
- Benign leiomyomas skin/uterus.
- Uterine leiomyosarcoma.
Microscopic
Features:[3]
- Large eosinophilic nucleolus with perinucleolar clearing - proposed hallmark - important.
- May be focal.
- Variable architecture:
- Papillary - classic description.
- Tubulopapillary.
- Tubular.
- Solid.
DDx:
IHC
