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
- Rare <1% - in a series of 615 cases.
- Males:Females ~ 7:1.[2]
- Prognosis - probably favourable.[2]
- Thought to be related to papillary renal cell carcinoma.[3]
Gross
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.
DDx:
- Papillary renal cell carcinoma (oncocytic variant).
- Hereditary leiomyomatosis renal cell carcinoma syndrome associated renal cell carcinoma.
- Renal oncocytoma.
- Cystic nephroma/Mixed epithelial and stromal tumour.
- Multilocular cystic renal neoplasm of low malignant potential (multilocular cystic renal cell carcinoma).
