Two synergistic scientific meetings joined forces to understand rare skin disorders and advance research and treatments for patients who suffer from these painful diseases

All researchers and medical professionals were invited to join us right before the 2024 Society for Investigative Dermatology Annual Meeting in Dallas, Texas for a remarkable collaboration of two groups dedicated to helping patients with pachyonychia (and other rare and painful palmoplantar keratodermas) and acantholytic (blistering) disorders.
