Welcome to the European Working Group
for Breast Screening Pathology (EWGBSP)
Self Evaluation Tool for Microinvasion in Breast Disease
This free evaluation unit consists of 50 challenging cases of in situ carcinomas of the breast with or without microinvasion.
You have two rounds to choose. We suggest doing the HE slides at first and as a second round the HE+IHC slides after several days.
You have also the choice to do the self-evaluation with a case by case feedback (suggest for beginners) or as a feedback at the end (suggested for experienced pathologists).
To view the morphological criteria of microinvasion used in this study, please click here.
Please note: The study was carried out with the definition of microinvasion including “invasion beyond the specialized stroma” criterion. However, in the latest WHO Classification of Breast Tumours (2012), stromal invasion is not differentiated between specialized and non-specialized stroma. Therefore some of these cases could be differently classified by reviewers today. (Note added in Oct. 2018 by G. Cserni)
Your results are neither stored nor will be used for any other reason than your personal self-evaluation.
We wish you a nice session!
ROUND 1 (HE Slides only) Feedback after every case (you will see your choice in comparison to the majority opinion of the EWGBSP members) Feedback at the end only (you will see a summary where you can recall all discrepant cases)
ROUND 2 (HE + myoepithelial IHC slides) Feedback after every case (you will see your choice in comparison to the majority opinion of the EWGBSP members) Feedback at the end only (you will see a summary where you can recall all discrepant cases)
