Collecting Duct Carcinoma is a rare tumor in renal medulla from the distal collecting (Bellini's) ducts and accounts for <1% of renal epithelial tumors (Diaz JI, Mora LB, Hakam A. The Mainz Classification of Renal Cell Tumors. Cancer Control. 1999 Nov;6(6):571-579).
Collecting Duct Carcinoma is a rare tumor in renal medulla from the distal collecting (Bellini's) ducts and accounts for ~1% of renal epithelial tumors (Diaz JI, Mora LB, Hakam A. The Mainz Classification of Renal Cell Tumors. Cancer Control. 1999 Nov;6(6):571-579). These tumors have been associated with an aggressive course and a poor prognosis; they often present with metastases at the time of diagnosis. The mean age of patients seems to be younger than that of patients with other renal tumors, although given the rarity of the tumor, this has been debated. The disease is more common in males than females and hs been reported to occur more frequently in African Americans.
