On behalf of the European Association for Haematopathology (EAHP) and the Society for Hematopathology (SH), it is with greatest pleasure to invite you to attend the 20th Meeting of the EAHP in Dubrovnik, Croatia. The meeting will take place at the Hotel Valamar Lacroma Conference Centre from 24 to 29 April 2021. This is one of the largest conference facilities in the region, located in a green oasis of the Babin kuk peninsula, 5 km from Dubrovnik’s Old Town and approximately 20 km from the airport. For the first time this meeting is being held in Eastern Europe, in the medieval stone walled city with impressive history and one of the UNESCO’s World Heritage sites. The EAHP is committed to improving haematopathology knowledge and raising the standards of education, research and clinical practice. With the main topic "Overlaps, borderlines and mimics", this meeting will be an opportunity to take stock of the state of haematopathology today, address the current contentious diagnostic issues and point the direction of future research. Dubrovnik is full of cultural and historical monuments dating back a thousand years, a city of festivals, museums, treasuries and galleries. The Organising Committee is committed to provide an interesting social programme to accompany the scientific sessions and facilitate professional networking.
