Morphology of congenital nevi in dermoscopy and reflectance confocal microscopy according to age: a pilot study.

Congenital nevi (CN) are pigmented lesions that undergo a morphological evolution during patient growth.(1,2) Few data are available regarding CN and the correlation between dermoscopy and reflectance confocal microscopy (RCM) throughout life stages. This cross-sectional study aimed to correlate CN dermoscopy and RCM patterns and identify the prevalent patterns according to age groups. We also described the representative RCM features associated with CN. This study was approved by the local Ethics Committee (n.237/17) and was conducted in accordance with the Declaration of Helsinki.
