Linear verrucous epidermal nevus with oral manifestations: report of two cases.

Linear verrucous epidermal nevi (LVEN) are characterized by verrucous papules often coalescing into well-demarcated skin-colored or brown plaques following the lines of Blaschko. We present two new cases of LVEN with oral mucosa involvement and briefly discuss this very rare finding. In both cases, oral biopsies showed hyperkeratosis, acanthosis, and papillomatosis. Although several treatment modalities have been reported for the cutaneous lesions, there is no consensus for the management of oral lesions so far.
