Adenocarcinoma of the urinary bladder, also primary adenocarcinoma of the urinary bladder and bladder adenocarcinoma, is a very uncommon malignant urinary bladder tumour.

General

Clinical:

Microscopic

Features:

  • Nuclear pleomorphism - may be mild.
  • Usually glandular differentiation (most common).
  • Without urothelial differentiation - essential.[3]

Subtypes:[2]

  • Glandular.
  • Papillary.
  • Colloidal (mucinous).
  • Signet ring cell carcinoma.
  • Clear cell carcinoma (also mesonephroid carcinoma).

DDx:

IHC

Features - variable:[4]
