Abstract

Inflammatory linear verrucous epidermal nevus is an uncommon subtype of epidermal nevus. It is characterized by linear hyperpigmented verrucous plaques along the lines of Blaschko. We report a 52 year-old Thai female presented with unilateral inflamed linear verrucous plaques distributed on left forearm along the lines of Blaschko since birth. Histologic findings revealed focal marked vacuolation with basophilic keratohyalin granules at granular cell layer coexisting with papillomatosis with alternated focal parakeratosis. The overall findings are compatible with ILVEN with unusual histopathologic pattern of epidermolytic hyperkeratosis.
