2021 IPCC Symposium June 28-29 VIRTUAL

All researchers, clinicians, and industry representatives interested in PC (and other rare skin conditions with PPK) are warmly invited by Professors Edel O’Toole and Eli Sprecher to join us for another special meeting of collaboration at:

The 17th Annual International Pachyonychia Congenita Consortium (IPCC) Symposium

Monday and Tuesday, June 28-29, 2021

8am-11am MDT Each Day
(10am-1pm EDT, 3pm-6pm UK, 4pm-7pm France, 5pm-8pm Israel Each Day)

to be held virtually



Please register and join us for presentations and discussions by those who are doing both clinical and translational research for PC and other PPKs. Also, if you know of others in your clinics and labs, or even students who may be interested in learning more about these rare skin diseases, please feel free to invite them to register and enjoy participating with some of the key leaders in our field.

We are excited to resume our yearly gathering of exceptional professionals who share concern regarding patients who deal with pain each day of their lives. Because despite the name Pachyonychia Congenita, PC is much more than thick nails!

Please contact us at info@pachyonychia.org with questions.
