Inflammatory linear verrucous epidermal naevi: a review of 23 cases.

Twenty-three patients diagnosed with inflammatory linear verrucous epidermal naevi (ILVEN) over a 13 year period are reviewed retrospectively. These ILVEN showed a predilection for the buttock and legs and were usually unilateral. Onset of the lesions was usually within the first 6 months of life and extension beyond the original margins occurred in 26% of cases. Sixteen of the 23 patients were male. Ten patients had ILVEN predominantly involving the left side, 12 were on the right side and, in one case, the side involved was not recorded.
