Tuberous sclerosis-associated renal cell carcinoma, abbreviated TSARCC, is a kidney tumour that is associated with the syndrome tuberous sclerosis.[1]
General
- Not in the WHO classification of renal neoplasia or the Vancouver modification of the WHO classification.
- Afflicts individuals at a younger age than sporadic renal cell carcinoma.[2]
- 2-4% of individual with tuberous sclerosis develop renal cell carcinoma.[3]
Microscopic
Features as per Guo et al.[1] describes three different morphologies:
- Renal angiomyoadenomatous tumour-like.
- Chromophobe renal cell carcinoma-like.
- Macrocystic architecture composed of cells with a granular eosinophilic cytoplasm.
Notes:
- The macrocystic architecture with cells with granular eosinophilic cytoplasm pattern in individuals without documented TSC is an evolving entity known as eosinophilic, solid and cystic renal cell carcinoma.[4]
- There is also a paper by Yang et al.; it describes three different patterns:[3]
- TSC-associated papillary RCC.
- Renal cell carcinoma, unclassified.
- Hybrid oncocytic/chromophobe tumour (HOCT).
DDx:
- Renal angiomyoadenomatous tumour.
- Chromophobe renal cell carcinoma.
- Renal oncocytoma.
- Papillary renal cell carcinoma.
- Hereditary leiomyomatosis renal cell carcinoma syndrome-associated renal cell carcinoma.
- Unclassified renal cell carcinoma.
