Dysplastic nevus syndrome is characterized by unusual nevi and multiple inherited melanomas. Skin manifestations can include scarring, eruptive melanocytic nevi, vulvovaginal stenosis, and dyspareunia. This is in contrast to the "nests" of multi-layer melanocytes found in moles (melanocytic nevi). Those with dysplastic nevi have an elevated risk of melanoma. Additional types of nevi do not involve disorders of pigmentation or melanocytes. Somewhat surprisingly, this also applies to those with dysplastic nevi. Clinically, epidermal nevi are similar to seborrheic keratoses in appearance. Dysplastic nevi are more likely than ordinary moles to become cancerous. NAME refers to nevi, atrial myxoma, myxoid neurofibromas, and ephelides. Epidermal nevi are usually present at or near birth. Repigmentation after laser treatment of congenital nevi or superficial curettage supports this concern. The disease is characterized by basal cell nevi, jaw keratocysts and skeletal abnormalities. Some individuals advocate the use of hair removal laser for the treatment of congenital nevi. These nevi represent excess growth of blood vessels, including capillaries. The cause of Spitz nevi is not yet known.
