Urothelial carcinoma, WHO grade 2, invading into lamina propria, no muscularis propria present in the photos for evaluation.
We usually use WHO/ISUP grading system which is low grade and high grade, 2 tiers. But the pictures shown here appear to be intermediate nuclear grade. So occasionally i will use the 3 tier WHO grading system. Maybe other areas show more clear features for high grade, i feel like high grade.
