Pediatric lupus and the role of sun protection.

Systemic lupus erythematosus (SLE) is an autoimmune disease that can affect many organs of the body. The skin is commonly targeted by the inflammatory process of SLE, and exposure to sunlight is known to be a potential cause of dermatologic as well as systemic manifestations of SLE. Sun protection is a critical part of treating the disease and preventing sequelae. While other manifestations of the disease are important, discussion will be limited to ultraviolet light (UVL) and the resulting abnormal response to light exposure that may occur in lupus. Education about the importance of sun protection is an integral part of the treatment of children with lupus.
