Small cell carcinoma of the urinary bladder, abbreviated SCCUB, is a rare malignant neoplasm of the urinary bladder.
General
- Very rare[1] - less than 1% of bladder cancers in one series.[2]
- Poor prognosis[1] - survival ~ 11 months.[2]
Clinical:
- Hematuria - typical presentation.[2]
Epidemiology:
Microscopic
Features:
- See small cell carcinoma.
Note:
- Usually co-exists with urothelial carcinoma ~60% of cases in one series.[2]
DDx:
- Small cell carcinoma of the prostate gland.
- Lymphoma, large cell.
- Other small round blue cell tumours.
