Tubulocystic carcinoma of the kidney, abbreviated TCCK, is a very rare kidney tumour.

In the Vancouver modification of the WHO classification of renal neoplasia, it is refered to as tubulocystic renal cell carcinoma (abbreviated TC-RCC).[1]

It is also known as low-grade collecting duct carcinoma.[2]

It should not be confused with collecting duct carcinoma, a very aggressive renal tumour.

General

Gross

  • Bubble wrap-like appearance - due to the cystic nature.[2][4]

Microscopic

Features:.[2]

  • Cysts of variable size lined by a single layer of epithelium that has a:
    • Cuboidal, flat, or hobnail morphology.
    • Eosinophilic cytoplasm.
    • Large nuclei with prominent nucleoli.
  • +/-Fibrotic stroma.

IHC

Features:[6]

  • CD10 +ve.
  • RCC +ve.
  • Vimentin +ve.
  • AMACR +ve.
  • CK7 -ve/+ve (focally in 2/3 tumours[7]).
