Case description (by case creator):
The first two images illustrate normal urothelium for comparison. There is a granuloma in the lamina propria, consistent with BGC therapy. The other images illustrate flat urothelium that shows variable loss of polarity and nuclear aytpia with enlargement and some hyperchromasia. CK20 immunohistochemistry shows diffuse full thickness positivity in the urothelium.
