2 - Borderline LG/HG
4 - Mixed LG & HG
#RCC
5 - Syncytial multinucleate giant cells
This week’s final posting of #GUPath #GradingChallenge cases (5 of 5)👇
Clear cell #RCC 6 cm. Is this WHO/ISUP grade 4?

Again share your thoughts #GU tweeples and let’s see the votes.

3 of 3. As shown there are 2 scenarios of “borderline” PUC:
1 - Morphology gray between LG & HG (so called LG/G2 vs HG/G2)
2 - Mixed LG & HG
#GradingChallenge
Case 2 - example of 1
Case 4 - example of 2
Thank you #GUPath tweeples! Last case (RCC) to follow!

This week’s 4th posting of #GUPath #GradingChallenge cases (4 of 5)👇
Papillary #urothelial carcinoma, non-invasive. How will you report the grade? (2016 WHO)
Please take the poll in comment.
Again share your thoughts #GU tweeples and will see the votes.

Final poll: GP4 by 68% of 191 votes
I thought this example highlights issue about solid cylinders or thick cords for GP5. This descriptors need further elaboration.
Thanks #GUPath tweeples for voting!

Final poll: GP5 by 57% of 224 votes
As already commented, solid with rosette-like spaces was added to GP5 by 2014 ISUP.
I guess lack of clear spaces distinguishes this from GP4.
