The “World Congress on Cancers of the Skin” and the “Congress of the European Association of Dermato-Oncology” (EADO) have become major interdisciplinary meetings for clinicians and basic scientists working in the challenging fields of Melanoma and Non-Melanoma Skin Cancer. Both meetings will be held together as a Joint Meeting covering the entire spectrum of cutaneous malignancies. It is our pleasure to host this unique Joint Meeting of the 16th World Congress on Cancers of the Skin and the 12th EADO conference in the historic Hofburg Conference Center in the heart of Vienna. We feel privileged and honoured that many of the world’s leading investigators in the field will actively participate in this meeting. Clinicians and researchers will focus on the state of the art in prevention, recognition, and treatment of cutaneous neoplasms covering melanoma and non melanoma skin cancer as well as lymphomas and rare skin tumours.
