With excellent presentations, a room packed with researchers, and many more standing in the back, our annual meeting of scientific collaboration to advance research and drug development for those who suffer from PC exceeded our expectations!

Date: May 10th, 2023
Time: 8:00 am to 1:00 pm, Tokyo, Japan
Location: Takao Room (42nd Floor) at the Keio Plaza Hotel Tokyo, Japan
The meeting was held in person in conjunction with the First International Societies for Investigative Dermatology (ISID) Meeting in Japan.
All researchers, clinicians, and industry representatives interested in PC (and other rare conditions with painful PPK) were invited to join at no cost.
For symposium attendees, PC Project hosted a traditional Japanese dinner Tuesday, May 9th (the night before the meeting) at 6:00pm JST at Koshitsu Izakaya Banya Nishi Shinjuku, 2-6-1 Nishi Shinjuku, Sjinjuku Sumitomo Bldg. 49 Floor, Shinjuku, Tokyo 163-0249. It was a lovely evening with good company, good food, and a spectacular view.
