It presents as a group of verrucous, closely grouped, skin-colored to brown papules often in a linear arrangement following the Lines of Blaschko (Fig. 43.1). It develops primarily in childhood. There are several variations of EN including localized nevus unius lateris, systematized EN, EN syndrome, and inflammatory verrucous epidermal nevus (ILVEN) (Fig. 43.2).
