Our themes


CMN (Congenital Melanocytic Nevus) can turn your life upside down. The diagnosis and treatment of giant birthmarks require physical, emotional, and mental endurance. As part of Naevus Global, we understand this better than anyone else.


Naevus Global strives for a better quality of life and improved quality of care for individuals dealing with giant birthmarks. Connecting to other people will help you find the best care. We try to connect you with support groups as close to you as possible.


Naevus Global connects to international organizations. Representing Congenital Melanocytic Naevi at international conferences will raise awareness and stimulate healthcare providers, researchers, and policymakers to improve healthcare.
