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. [2] It is also recently described; a 2002 review found just 40 case reports worldwide. [3] Previously, due to its location, CDC was commonly diagnosed as renal cell carcinoma or a subtype of renal cell carcinoma. [4] However, CDC does not respond well to chemotherapy drugs used for renal cell carcinoma, and progresses and spreads more quickly.
Signs and symptoms are as for kidney cancer.[ citation needed]
Histologic examination of collecting duct carcinoma demonstrates an infiltrative lesion with tubulopapillary, irregular channels lined by high grade hobnail cells with marked desmoplastic response and brisk neutrophilic infiltrate.[ citation needed]

CDC was thought to be renal cell carcinoma, until "recently developed techniques of lectin histochemistry" helped forward knowledge of kidney duct cancers. [5]
