title: Epidermal naevi treated with pulsed erbium:YAG laser.
abstract: Epidermal naevi are common and can cause marked cosmetic disability. Ablative laser treatment may be successful in their removal, but may result in significant scarring. Surprisingly the erbium:YAG laser is rarely reported for this indication even though it produces minimal tissue damage. We report our experience using this laser to treat six patients with epidermal naevi. Patients (five female, one male; aged 4-41 years) underwent treatment with pulsed 2940 nm erbium:YAG laser at 0.4-0.45 J/cm(2), 2 mm spot size at 4 pulses/s. All six patients had excellent cosmetic results at follow up ranging from 6 to 60 months. The favourable results were dependent on selection of cases with superficial or small, discrete lesions which could be ablated accurately. The erbium:YAG laser is therefore an effective treatment for relatively nonverrucous or papular epidermal naevi.
