Micrograph showing renal cell carcinoma in the context of tuberous sclerosis complex. H&E stain. (WC/Nephron)

Tuberous sclerosis-associated renal cell carcinoma, abbreviated TSARCC, is a kidney tumour that is associated with the syndrome tuberous sclerosis.[1]

General

Microscopic

Features as per Guo et al.[1] describes three different morphologies:

  1. Renal angiomyoadenomatous tumour-like.
  2. Chromophobe renal cell carcinoma-like.
  3. Macrocystic architecture composed of cells with a granular eosinophilic cytoplasm.
