Increasing proportions of atypical intraepidermal melanocytic proliferation on various parts of the body may increase the likelihood of a diagnostic change to melanoma after Mohs micrographic surgery, according to findings presented at the American Society for Dermatologic Surgery Annual Meeting.
Jeremy Etzkorn, MD, assistant professor of dermatology at the Hospital of the University of Pennsylvania, Philadelphia, and colleagues suggested that surgical margins and patient counseling for atypical intraepidermal melanocytic proliferation and melanoma may be different.
The retrospective, cross-sectional study included 198 patients with atypical intraepidermal melanocytic proliferation on the head, neck, hands and feet. Eligible participants underwent Mohs micrographic surgery at the University of Pennsylvania between August 2008 and March 2016.
