“Not all butterfly rashes are lupus - that’s important to note eczema is one example of a skin condition that may look like butterfly rash,” he says. One way to make that diagnosis is through a biopsy, in which a doctor takes a tissue sample and examines it under a microscope. It has a lot of mimics, or other conditions that can appear to be butterfly rash, so it needs to be distinguished from those,” says Stojan. This type of rash, as well as most lupus rashes, are generally inflamed, and so it’s edematous, it’s raised, and it's red. “About 90 percent of patients who get malar rash have systemic lupus. The rash can also occur on the arms, legs, and body, she adds.

Lupus rash and skin changes often accompany other symptoms of lupus, which can include fatigue, pain and swelling in the joints, and swollen glands.
“The immune response targets the skin cells and causes inflammation that leads to the rashes,” he says. An antigen is any substance that causes the immune system to react, often by producing antibodies to fight against it. “The UV radiation damages the cells in the skin, and that exposes antigens that the immune system recognizes, and that leads to an immune response in the skin,” says Dr. “It’s thought that the rashes occur because of exposure to sunlight,” says George Stojan, MD, an assistant professor of medicine in the division of rheumatology at the Johns Hopkins University Medical School and the codirector of the Hopkins Lupus Center in Baltimore. Approximately two out of every three people with lupus will develop some type of skin disease, known as cutaneous lupus erythematosus, according to the Lupus Foundation of America. Lupus can also affect the skin and cause a rash or other kinds of skin changes. This response creates inflammation in many parts of the body, including the joints, kidneys, brain, heart, and lungs.
