- Recently, members of the World Health Organization and International Society of Urologic Pathology published guidelines for the classification of urothelial neoplasms.
- This system was based upon earlier works and classification systems and is meant to serve as a springboard for future studies that will help refine this classification and enabling better correlation of urothelial lesions with their biologic behavior using uniform terminology.
- This classification system of urothelial neoplasms has been recently published (American Journal of Surgical Pathology 1998 Dec;22(12):1435-48)
Purpose of this Web site:
- To provide representative cases of each urothelial lesion to aid in the introduction of this classification system and promote its uniform usage.
- This web-site is divided into two sections. The first is dedicated to papillary urothelial neoplasms and the second is dedicated to flat urothelial neoplasms.
How to use this Web site:
- When you continue below you will be asked to create a logonID and password and then you will be asked to provide demographic information and your e-mail address. This information will only be used by Johns Hopkins Pathology to catalog the usage of the web site and make you aware of future pathology related web sites.
- You can proceed sequentially through this web site or compare urothelial lesions.
- You may provide feedback by selecting the "Feedback" button on the bottom of each page. Please focus feedback on specific cases if it is appropriate.
