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

It is also known as low-grade collecting duct carcinoma.[1]

General

  • Not in the WHO classification of renal tumours - as of 2013.[2]
  • Rare <1% - in a series of 615 cases.
  • Males:Females ~ 7:1.[1]
  • Prognosis - probably favourable.[1]

Gross

  • Bubble wrap-like appearance - due to the cystic nature.[1]

Microscopic

Features:.[1]

  • 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:[2]
