The World Congress of Dermatology (WCD) was first held in Paris, France, in 1889. It represents the largest and most prominent international meeting on this medical specialty. The 23rd WCD took place in Vancouver, Canada, in May 2015 and notably hosted the 9th International Congress on Cutaneous Adverse Drug Reactions (CADRs). From June 10 to 15, 2019, the 24th WCD took place in Milan, Italy, under the auspices of the International League of Dermatological Societies and hosted by the Italian Society of Dermatology. WCD 2019 was a major success, with over 16,000 attendees from more than 140 countries. Six sessions were either dedicated to or contained presentations related to CADRs: Life-Threatening Drug Reactions, Managing the Suspected Drug Reaction, Common Drug Reactions, Update on Dermatopathology, Autoimmune Dermatoses and Adverse Drug Reactions, and Cutaneous Reactions to New Drugs. Like its predecessors, WCD 2019 was an exemplary international scientific meeting at which ground-breaking advances in dermatology were presented. Numerous presentations focused on CADRs and highlighted updates and discoveries, especially pertaining to pharmacogenetics and cutaneous side effects of targeted therapies.
