The State of the Dysplastic Nevus in the 21st Century


The dysplastic nevus has been the source of much controversy and debate since the term was coined in the 1970’s. Many studies regarding this histologic entity have been performed over the years and the debate still exists about proper diagnosis and management of these nevi. The lecture will elucidate some of the recent advances in understanding these distinct entities and their relationship to melanoma risk.

Originally presented on February 12, 2019 in Park City, Utah.
