Our membership is worldwide and currently more than 150 countries are represented. Our organization conducts a world congress every 3 years and sister society meetings every year during the AAD congress in US and the EADV congress in Europe. The IDS has been founded in 2003 by H. Peter Soyer, Rainer Hofmann-Wellenhof and Giuseppe Argenziano to promote clinical research in dermoscopy and to represent a clinically oriented international organization with a thrust towards helping and improving education in dermoscopy. We welcome your participation in the International Dermoscopy Society!
