Non-Transitional Cell Carcinoma Of The Bladder

Abstract The most common carcinomas of the urinary bladder, up to 90%, arise from the urothelium and are referred to as urothelial or transitional cell carcinomas (TCC). While transitional cell carcinomas predominantly occur in organs lined by urothelium, the other carcinomas of the urinary bladder are also seen at diverse sites in the body. The other carcinomas include squamous cell carcinoma and its variants, adenocarcinoma and its variants, and undifferentiated carcinomas such as small cell carcinoma, lymphoepithelioma-like carcinoma, and giant cell carcinoma (Table 7.1).
