“…Acquired melanocytic nevi with a globular pattern were significantly more frequent on the upper than the lower back on two dermoscopic studies. 21,22 One study in high-(n = 34) versus moderate-to low-risk (n = 31) patients demonstrated that dermoscopic nevus patterns were similar for age and body site in people at different levels of melanoma risk. They found more globular patterned nevi on the head, neck, chest, and abdomen; reticular and nonspecific nevi (including homogeneous nevi) on the trunk; and nonspecific nevi on the upper and lower limbs on both groups.…”

Background and Aim: Verrucous epidermal nevi are cutaneous hamartomas having many clinical variants. Dermoscopic features of verrucous epidermal nevus have rarely been investigated. We aimed to identify dermoscopic findings of the entity which will facilitate the diagnostic process by reducing the use of invasive diagnostic methods. Material 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 most common vessel pattern was dotted vessels. Branched thick brown lines, brown globules, brown dots forming lines, serpiginous brown dots, white and brown exophytic papillary structures, fine scale, thick adherent scale and cerebriform structures were the other findings. Conclusion: We observed many vascular and non-vascular dermoscopic findings which have not been described previously for the entity. Dermoscopic examination of the verrucous epidermal nevi may lead more reliable clinical interpretation and thus it may reduce the need for histopathological investigation. Keywords: dermoscopy, large brown circles, verrucous epidermal nevus

Dermoscopy is a non‐invasive, in vivo imaging technique known to increase the diagnostic accuracy for melanoma and improve the benign‐to‐malignant biopsy ratio by increasing the detection of melanoma while decreasing the number of naevi being biopsied. Melanocytic naevi are the primary lesions in the differential diagnosis of early melanomas. While the clinical morphology of naevi and melanoma often overlap, dermoscopy has improved the ability to discriminate between the two by visualisation of colours and structures that are otherwise not visible to the naked eye. In general, naevi tend to display a symmetrical and organised dermoscopic pattern while melanomas tend to reveal melanoma‐specific structures distributed in an asymmetrical and disorganised manner. The structures found to be associated with melanoma on non‐glabrous skin include atypical network, negative network, streaks, shiny white lines, atypical dots/globules, off‐centred blotch, blue‐white veil, regression structures, atypical vessels and peripheral tan structureless areas. Due to the unique microanatomy of other anatomical sites such as the face and glabrous skin, additional dermoscopic features have been identified that help in the detection of melanoma in these sites. This chapter provides an overview of the dermosocopic structures and patterns associated with naevi and outlines the dermoscopic structures associated with melanoma.
