title: Histologic changes resembling the verrucous phase of incontinentia pigmenti within epidermal nevi: report of two cases.
abstract: A wide spectrum of histopathologic changes has been reported to occur within epidermal nevi. We saw two patients with warty nevoid lesions in which histopathologic features of incontinentia pigmenti, verrucous phase, were present. The diagnosis of incontinentia pigmenti was excluded because both patients were male, lacked a preceding vesicular stage, and did not demonstrate other features of the disorder.
