Cutting Edge Pathology

We are currently facing a never seen and very difficult situation worldwide.

Please see a letter from ESTP, ESVP and ECVP chairs and their Scientific and Local Organizing Committees, informing you about the decision to postpone our joint Cutting Edge Pathology congress by one year, to the end of August / beginning of September 2021 in Torino, Italy.
We are sure that you understand the necessity to make this decision. We ensure you to inform you as soon as possible about the new dates for the congress in Torino.

This year's Annual General Assembly will be conducted virtually (GoTo webinar format), on 27th August 2020, from 2:00 to 4:00 pm CEST.
