Collecting duct carcinoma, also known as Bellini duct carcinoma[1] and carcinoma of the collecting ducts of Bellini, is a rare aggressive kidney tumour.

It should not be confused with tubulocystic carcinoma of the kidney (also known as low-grade collecting duct carcinoma).

General

  • Rare.
  • Poor prognosis.
  • Usually central location.
  • Typically young adults.

Gross

  • Medullary location - as opposed to cortical.[2]

Microscopic

Features:[3]

  • Tubular structures with tapered ends.
    • May be described as tubulopapillary.
  • Hobnail pattern - cell width smaller at basement membrane than free surface.[4]
  • High grade nuclear features (nuclear pleomorphism).
  • High mitotic rate.

Notes:

  • Benign urothelium must present to excluded urothelial carcinoma.
  • Desmoplastic stroma may be prominent.

IHC

Features:[6]

  • HMWCK +ve.
  • LMWCK +ve.
  • CD117 +ve.
  • E-cadherin +ve.
  • CD10 -ve.
  • AMACR -ve.
  • PAX8 +ve.[7]

UCC:

  • CK20 +ve.[6]
  • p63 +ve.[7]
  • CK5/6 +ve.
  • PAX8 -ve.[7]
