The skin is a window to your health. Such is the case with many autoimmune disorders. More common in women, this group of disorders is characterized by dysregulation of the immune system whereby it attacks your own healthy cells. The butterfly rash of systemic lupus, the scarring dark lesions of discoid lupus, the thickening of the skin in scleroderma, and the white spots in vitiligo are some examples of the cutaneous manifestation of autoimmune disorders. A dermatologist maybe the first physician who confirms your suspicion of an autoimmune disorder.
