Core Tip

Core Tip: The currently used classification for histologic subtypes (HS) in urothelial carcinoma has mainly been described in muscle invasive bladder cancer. However, a subset of non-muscle invasive bladder cancer presents HS, and their presence is clinically relevant. In this minireview, we discuss the epidemiology, classification, characterization and the clinical relevance of HS in non-muscle invasive bladder cancer.
