Abstract Background Most of the knowledge on the prevailing dermoscopic patterns of acquired melanocytic nevi ( AMV ) is based on studies in Caucasians, while little research focuses on the dermoscopic variability in nevi in skin of colour. Objective To analyse the prevalent dermoscopic nevus patterns in subjects with a skin type ( ST ) V and VI . Methods Prospective, cross‐sectional, morphological study was conducted in six clinics with enrolment of consecutive individuals with a ST V or VI . Digital dermoscopic images of selected representative AMN were assessed for dermoscopic colours, morphological patterns and pigment distribution. Results Analysis of 300 nevi from subjects with ST V and VI revealed significant differences in the nevus pattern between these two groups. The majority of nevi in ST V revealed a reticular pattern, whereas persons with ST VI more frequently exhibited a structureless pattern. Black, blue and grey were more frequent in ST VI , whereas the vast majority of nevi in ST V individuals showed dark brown colour. Conclusions Our study provides new insights into the nevus pattern in individuals with a dark pigmentary trait, which may aid the diagnosis and management of nevi in this patients group.
