Two cases of unilateral verrucous nevus.

We report two patients with epidermal nevus: one with linear verrucous nevus and one with inflammatory linear verrucous epidermal nevus. The patients first showed manifestations of nevus at different ages (soon after birth and at the age of seven), and the findings progressed differently. In both cases, warty plaques were located unilaterally, strictly following Blaschko's lines.
