Comparison of treatment modalities for epidermal nevus: a case report and review.

For the past 2 years, we have been treating a teenage girl for a disfiguring, extensive, inflammatory linear verrucous epidermal nevus (ILVEN). In this one patient, we examined the efficacy of numerous treatment modalities and compared our results with those reported in the literature. In our experience, cryotherapy using liquid nitrogen proved to be the most successful therapy, and we have subsequently used it to treat almost all of this patient's lesions. Although cryotherapy does not provide an easy or dramatic cure, we believe it does produce reasonably good cosmetic results.
