collecting duct carcinoma

collecting duct carcinoma

A rare (1% of kidney cancers) tumour that arises in the renal collecting duct epithelium, often in middle-aged males (male:female, 2–4:1).

DiffDx
Papillary lesion (e.g., transitional cell carcinoma), metastatic carcinoma, renal medullary carcinoma.

Prognosis
Often advanced when diagnosed, some are very aggressive with half metastasising to regional nodes.

Major histopathological subtypes include clear cell carcinoma, papillary carcinoma, chromophobe carcinoma, collecting duct carcinoma, medullary carcinoma, and unclassified categories [8].
Subtypes of renal carcinoma include clear cell, papillary, chromophobe, medullary, and collecting duct carcinoma. Chromophobe carcinoma (ChC) comprises approximately 5% of all renal cell carcinomas (RCC) [1].
Only six cases of tubulocystic carcinoma that derived from the bile duct have been reported as subtype of the collecting duct carcinoma of the kidney in abstracts of the 102nd United States and Canadian Academy of Pathology (USCAP) annual meeting in 2013, and the details of the entity are unknown.
