Collecting duct carcinoma
Collecting duct carcinoma (CDC) (also known as Bellini duct carcinoma), 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. It is also recently described; a 2002 review found just 40 case reports worldwide. Previously, due to its location, CDC was commonly diagnosed as renal cell carcinoma or a subtype of renal cell carcinoma. However, CDC does not respond well to chemotherapy drugs used for renal cell carcinoma, and progresses and spreads more quickly.
==Histology==
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.
