Warts are common benign epithelial keratinocyte proliferations caused by human papillomavirus (HPV) infection that may involve the skin (cutaneous warts) and the mucous membranes (anogenital warts). The main dermatoscopy pattern suggestive of common warts is the presence of irregular whitish structures (mosaic pattern), typically associated with irregularly distributed, hemorrhagic reddish to black dots. In exophytic lesions, multiple papillomatous projections (fingerlike) containing elongated and dilated vessels that are surrounded by whitish halos may be observed. Papular anogenital warts show a whitish network circumscribing areas centered by dilated glomerular or dotted vessels (mosaic pattern), whereas cauliflower-like warts reveal multiple, irregular whitish projections arising from a common base and comprising elongated and dilated vessels that are usually more pronounced at the periphery.
