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.
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.
- Papillary - classic description.
Notes:
- Not common: psammoma bodies, foamy macrophages.[2]
DDx:
- Papillary renal cell carcinoma (type 2).
- Tubulocystic carcinoma of the kidney.
- Collecting duct carcinoma.[3]
- Renal medullary carcinoma - cells also have a prominent nucleolus.
