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. Multiple sessions were dedicated to CADRs that deserve to be highlighted. With the progressive development of new drug therapies such as biologics in dermatology, CADRs and, by corollary, drug safety are crucial topics that require our attention in a modern era of personalized medicine. 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. In total, 28 presentations on CADRs were delivered by delegates from 15 countries: Canada, China, France, Germany, India, Israel, Japan, Mexico, Saudi Arabia, Singapore, South Africa, Taiwan, the United Kingdom, and the USA. This report summarizes new discoveries and updates presented at WCD 2019. The presentations have been organized according to the sessions in which they were presented.
