Extensive Primary Anetoderma Refractory to Erbium YAG Fractionally Ablative Laser
Primary anetoderma is a rare elastolytic disorder characterized by well-circumscribed flaccid, atrophic macules and patches caused by focal loss of elastic fibers. Anetoderma is divided into two forms: primary, which is idiopathic and occurs on clinically normal skin, and secondary, which follows a prior dermatosis. Although it is indolent, the lesions of anetoderma persist and may be associated with significant aesthetic changes causing potential psychosocial difficulties. Anetoderma has been successfully treated with ablative, pulsed dye and non-ablative fractionated lasers. Patients with secondary anetoderma and anetoderma limited to a relatively small body surface area may be more amenable to laser treatment than patients with extensive involvement.
