o Cutaneous refers to the skin, and this form of lupus is limited to the skin. Although there are many types of rashes and lesions (sores) caused by cutaneous lupus, the most common rash is raised, scaly and red, but not itchy. It is commonly known as a discoid rash, because the areas of rash are shaped like disks, or circles. Another common example of cutaneous lupus is a rash over the cheeks and across the bridge of the nose, known as the butterfly rash. Other rashes or sores may appear on the face, neck, or scalp (areas of the skin that are exposed to sunlight or fluorescent light), or in the mouth, nose, or vagina. Hair loss and changes in the pigment, or color, of the skin are also symptoms of cutaneous lupus.
o Approximately 10 percent of people who have cutaneous lupus will develop systemic lupus. However, it is likely that these people already had systemic lupus, with the skin rash as their main symptom.
