ABSTRACT

Inflammatory linear verrueous epidermal nevus (ILVEN) first mentioned by Unna in 1896 is a rare variant of epidermal nevus characterized clinically by early onset in childhood, moderate to marked pruritus and persistent clinical course and histopathologically by predominant features of a chronic dermatitis or psoriasis. We present tbe first recorded case of a typical ILVEN developed in a 20-year-old Korean male, who has had an intensely pruritic linear verrucous patch, involving the entire length of the posterior aspeet of right upper extremity, volar aspect of right thumb and nails of ind.ex and ring finger since 5 years. Microscopic examination of the skin, biopsy specimens from the lesion on the right elbow joint area and the palm showed hyperkeratosis witb focal parakeratosis, moderate to marked acanthosis and elongation of rete ridges and papilla with mild exocytosis and moderate perivascular lymphocytic infiltration. Literature were reviewed.
