Nevus Vacuolization of keratinocytes : epidermolytic hyperkeratosis
1). Linear verrucous plaque at birth: Epidermal nevus
2). Incontinenta pigmenti: do not see vauolisation
3). Inflammatory linear verrucous epidermal nevus (ILVEN) presents as erythematous and verrucous papules, which are arranged in a linear array.
4). The lesions are characteristically pruritic. ILVEN is usually unilateral and is frequently located on an extremity.
5). Children are most commonly affected (girls more often than boys), often prior to the age 2). Clinically, ILVEN must be distinguished from other epidermal nevi, linear psoriasis, and lichen striatus.
6). Unlike linear epidermal nevus, ILVEN is characteristically erythematous and pruritic.
7). Unlike linear psoriasis, ILVEN is often difficult to treat and presents in early childhood.
8). ILVEN is pruritic and does not spontaneously regress, which often occurs in lichen striatus
