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).
Prostatic urothelial carcinoma and urothelial carcinoma of the prostate gland redirect here.
General
- May arise secondary to radiotherapy for prostate cancer.[1][2]
- Spreads from the urinary bladder usually - common.[3]
- Identified by endoscopic loop biopsy[4] or TURP.
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:
- Stromal invasion.
- Without stromal invasion.
Notes:
- Stromal involvement common ~ 75% of cases.[5]
DDx:
- Urothelial carcinoma-like prostatic carcinoma - may have pseudopapillae.
