Urothelial carcinomas (UC) are likely to have particular morphological features that distinguish them from the typical form. These original aspects are called “histological variants of urothelial carcinoma”. They can constitute all or part of the tumor and concern mainly muscle invasive UC and high grade. Their frequency varies according to the type, but the knowledge of these variants is essential because of the diagnostic difficulties, and the implication of their presence on the prognosis.
