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

Urothelial carcinoma of the urethra
Diagnosis in short
Site urethra - also see prostate (prostate cancer)
Clinical history +/-radiation therapy, bladder cancer
Prevalence uncommon
Treatment cystoprostatecomy/cystectomy or endoscopic resection

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

General

Treatment:[4]

  • 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.[5]
