Dermoscopic Features of Congenital Melanocytic Nevus and Becker Nevus in an Adult Male Population: An Analysis with a 10-Fold Magnification

Abstract

(1) The same dermoscopic features observed in small and medium-sized CMN by video-dermoscopy with high magnifications are also detectable in medium-sized and large CMN, employing the dermoscopy with the 10-fold magnification. (2) Network, focal, skin furrow and perifollicular hypopigmentation, hair follicles and vessels could be considered as peculiar dermoscopic features of BN. (3) Major differences in the frequency of dermoscopic characteristics were detected between CMN and BN, and dermoscopy seems to provide some diagnostic aid in differentiating CMN from BN in equivocal cases.
