Hyperplastic foci can be focal, multifocal, or diffuse. ## 英文原文 · Recommendation Urothelial hyperplasia should be diagnosed and given a severity grade. In areas of inflammation or with the presence of calculi, the pathologist should use his or her judgment in deciding whether secondary urothelial hyperplasia is prominent enough to warrant a separate diagnosis.
