Primary outcomePrimary: Frequency of BRAF Mutations Among Nevi — 6; 19 BRAF mutations
Summary
This project is a multicenter study in which we will investigate a dual concept of nevogenesis. Study location is the Department of Dermatology at the Medical University of Graz in collaboration with centers in Austria (Vienna), Italy (Naples, Benevento, Modena), Spain (Barcelona) and the United States (New York).
The hypothesis is that small congenital melanocytic nevi (CMN), "early" acquired melanocytic nevi in childhood (AMN) and dermal nevi, all dermatoscopically characterized by globular pattern, belong to the same spectrum of genetically determined melanocytic proliferations that develop due to endogenous pathways, in contrast to "true" acquired melanocytic nevi, dermatoscopically showing reticular pattern, that develop due to exogeneous factors such as UV-exposure.

Eligibility Criteria
Inclusion Criteria
- Healthy individuals aged 9 to 80 years showing one or more dermoscopically benign nevi with either uniform globular-cobblestone pattern or reticular pattern or a combination of both types
Exclusion Criteria
- Children under the age of 9 years
