A 16-year-old man, with no similar cases in the family, consulted for brown wart lesions that appeared at the age of two years with an extensive tendency for 4 years (Fig. 1a and 1b). Clinical and histological examination was in favor of an inflammatory linear verrucous epidermal nevus (ILVEN). Retinoids were tested without any improvement and laser was indicated but the patient was lost to follow-up. ILVEN is a rare condition corresponding to benign epidermal hyperplasia, which present clinically in the form of unilateral hyperkeratotic linear lesions resulting from a phenomenon of genomic mosaicism. Evolution is chronic with exudative and pruritic flare-ups. A secondary extension of the lesions is also possible as in our patient. Various anomalies may be associated such as aplasia of a limb part. Distinction with linear psoriasis can be difficult histologically. Retinoids and local corticosteroids are not very effective, surgical excision is sometimes practiced and CO2 laser finds its place in this indication with satisfactory results [13].
