Study to Test Genetic Alterations Among Different Dermoscopic Types of Melanocytic Nevi.

The investigations to this study will verify whether small CMN, "early" AMN and dermal nevi, characterized by globular pattern differ in their genetic alterations compared to reticular typed nevi. It will be expected that globular typed nevi and eventually dermal nevi lack B-RAF mutations whereas reticular nevi show alterations in the B-RAF gene. Study location: Graz
