Dermoscopic aspect of verrucous epidermal nevi: new findings

Background/aim: Verrucous epidermal nevi are cutaneous hamartomas with many clinical variants. Dermoscopic features ofverrucous epidermal nevus have rarely been investigated. We aimed to identify dermoscopic findings of the entity which will facilitatethe diagnostic process by reducing the use of invasive diagnostic methods.Materials and methods: The study included the patients with histopathologically approved verrucous epidermal nevus. Clinical,dermoscopic, and histopathological features of the patients were retrospectively reviewed and the findings identified were recorded.Dermoscopic examination was performed with a polarized-light handheld dermoscope with 10-fold magnification.Results: The most common dermoscopic features were thick brown circles, thick brown branched lines, and terminal hairs. The mostcommon vessel pattern was dotted vessels. Branched thick brown lines, brown globules, brown dots forming lines, serpiginous browndots, white and brown exophytic papillary structures, fine scale, thick adherent scale, and cerebriform structures were the other findings.Conclusion: We observed many vascular and nonvascular dermoscopic findings which were not described previously for the entity.Dermoscopic examination of the verrucous epidermal nevi may lead to more reliable clinical interpretation and thus may reduce theneed for histopathological investigation.
