Because most urothelial tumors are malignant epithelial tumors, fibroepithelial polyps are commonly mistaken for transitional cell carcinomas. However, because fibroepithelial polyps and malignant urothelial tumors typically present in different patient populations, different locations in the urinary tract, and appear different radiographically, distinguishing features between these entities is helpful in determining the differential diagnosis of a urothelial mass. In the appropriate clinical setting, fibroepithelial polyps should be considered in the differential diagnosis, which will affect surgical treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
