Scleroderma is a chronic disease of connective tissue characterized by deposition of large amounts of collagen. Localized scleroderma affects only the skin, whereas systemic disease, systemic sclerosis, may affect the lungs, gastrointestinal tract, kidneys, and heart in addition to the skin. Although the various forms of localized scleroderma are not life threatening, they result in considerable morbidity owing to joint contracture, loss of flexibility, and disfigurement. Although many different treatments have been attempted, until now none has proven to be effective. Accumulating evidence indicates that UVA irradiation offers a genuine opportunity to ameliorate localized scleroderma and the cutaneous manifestations of systemic sclerosis.
