Urothelial carcinoma of the urethra is uncommon. It may be primary, i.e. arises in the urethra, or secondary (spreads from the bladder or upper genitourinary tract).

Prostatic urothelial carcinoma and urothelial carcinoma of the prostate gland redirect here.

General

Treatment:[3]

  • Cystoprostatectomy - stromal invasion or extensive intraductal involvement.
  • Endoscopic resection and BCG - limited extent without stromal invasion.

Clinical DDx:

  • Benign urethral stricture.

Microscopic

Features:

  • Divided into tumours with:
    1. Stromal invasion.
    2. Without stromal invasion.

Notes:

  • Stromal involvement common ~ 75% of cases.[4]

PROSTATE TISSUE, TRANSURETHRAL RESECTION:
- HIGH-GRADE UROTHELIAL CARCINOMA WITH FOCAL STROMAL INVASION, AND EXTENSIVE
  INTRADUCTAL SPREAD IN FRAGMENTS WITH BENIGN PROSTATIC GLANDS.
