Sarcomatoid urothelial carcinoma (abbreviated sarcomatoid UC), also sarcomatoid urothelial cell carcinoma (abbreviated sarcomatoid UCC), is a rare variant of urothelial carcinoma.[1]
General
- Rare[1] approximately 0.1% of bladder carcinomas - based on the SEER database in the time span 1973-2004.[2]
- Aggressive >55% dead within one year of presentation.[1]
Gross
Microscopic
Features:
- Urothelial carcinoma (classic or recognizable variant).
- Sarcomatoid differentiation - typically (undifferentiated) spindle cells.
- Approximately have 10% of heterologous elements,[1] e.g. chondrosarcomatous differentiation, osteosarcomatous differentiation.
DDx:
- Sarcoma - esp. those arising from the retroperitoneum.
IHC
- GATA3 +ve (16 +ve of 22 cases[5]).
Images
Sarcomatoid UCC - low mag.
Sarcomatoid UCC - intermed. mag.
Sarcomatoid UCC - high mag.
