Collecting duct carcinoma (CDC) is a type of kidney cancer that originates in the papillary duct of the kidney. It is rare, accounting for 1-3% of all kidney cancers.{{cite journal| vauthors = Fakhrai N, Haitel A, Balassy C, Zielinski CC, Schmidinger M| title = Major response and clinical benefit following third-line treatment for Bellini duct carcinoma| journal = Wien. Klin.
