Abstract excerpt
AIMS: PAX8 immunohistochemistry (IHC) is often used to distinguish urothelial carcinomas (UCs) from tumours of renal and Mullerian origin. However, some UCs have been shown to be PAX8-positive. This study investigates the frequency of PAX8-positive conventional UCs of the urinary bladder without subtype morphology and/or divergent differentiation and their molecular profiles. METHODS: One hundred and one...
