Successful treatment of verrucous epidermal nevus with fractional micro-plasma radio-frequency technology and photodynamic therapy.

Verrucous epidermal nevus (VEN) is a skin disorder that commonly presents at birth; it is characterized by skin-colored to brown verrucous papules in a linear distribution following Blaschko's lines. Even though it is extremely rare, VEN has been associated with malignant transformation. VEN has been treated by different treatment modalities with varying and frustrating results. We introduce a new type of treatment. The fractional micro-plasma radio-frequency (RF) technology, which uses unipolar RF technology to provoke plasma spars, creating multiple controlled micro-perforations on the skin. Photodynamic therapy (PDT) is a type of technology for disease diagnosis and treatment, in which a photosensitizer gathers within the nidus and kills the diseased cells. In this report, we present a case of VEN that was successfully treated with fractional micro-plasma RF technology and PDT without side effects or complications; a follow-up was conducted after 24 months and no signs of recurrence were observed.
