Overview
Transitional cell carcinoma is a type of cancer that originates in the kidney, bladder or ureter. It is the most common type of bladder cancer. It arises from the transitional epithelium lining found in these organs.
Classification
Based on the growth pattern, transitional cell carcinoma may be classified into either papillary urothelial carcinoma or non-papillary urothelial carcinoma. Transitional cell carcinoma may be classified according to World Health Organization in a collaborative effort conjointly with the International Society of Urological Pathologists (ISUP) into two groups: infiltrating urothelial carcinomas and non-invasive urothelial carcinomas.[1] Based on the degree of cellular differentiation, transitional cell carcinoma may be classified into two grades: low grade and high grade.
