[Inflammatory verrucous epidermal nevus (IVEN)].

From the original description of Altman and Mehregan (1971) a new clinical type of linear nevus is known as inflammatory linear verrucous epidermal nevus (ILVEN). Two girls of 5 and 4 years of age are reported. One of them had good therapeutical results with the use of trichloroacetic acid. The clinical and histopathological aspects of this nevus are reviewed and the differential diagnosis should be done with: lichen planus, lichen striatus, linear psoriasis, zoniform dermatitis, naevus unius lateris.
