Two Cases of Inflammatory Linear Verrucose Epidermal Nevus / 대한피부과학회지

ABSTRACT

Inflammatory linear verrucose epidermal nevus(ILVEN) is characterized by an early age of onset, predominance in females, pruritus, unresponsiveness to treatment, and a distinctive inflammatory and psoriasiform histologic appearance. We present two cases of typical ILVEN. One of them was a 16-year-old male, who had had a mild pruritic linear verrucose patch involving the right arm which grew slowly for about 8 years. The other case was a 14-year-old girl whose lesion appeared at the age of 13. This lesion was localized on the right posterior thigh and showed linear distribution and verrucose appearance. Histopathological findings of two cases showed hyperkeratosis with foci of parakeratosis, moderate to marked acanthosis, elongation of the rete ridges, and occasional slight spongiosis, and chronic inflammatory infiltration in the dermis.
