Q. Is a rash a symptom of lupus?

My Sister has lupus for several years now. I recently developed a rash on my face. Is this a symptom of lupus? Could I have also been infected with this disease?
A1Lupus has not been proven to be hereditary. Therefore, the fact your sister has lupus shouldn't cause you to beleive you too will develop it. Also a rash is not enough to diagnose lupus. Physicians have to gather information from a variety of sources: past medical history, lab tests and current symptoms. They use a list of 11 criteria to help diagnose SLE. A person needs to satisfy at least 4 out of the 11 criteria before the diagnosis can be pinpointed. Some criteria, such as a biopsy diagnosis of kidney lupus, can carry more weight.
A2A rash could be a symptom of cutaneous lupus. The symptoms of cutaneous lupus may include a variety of different looking skin rashes, photosensitivity (where exposure to ultra-violet light triggers a rash), and sometimes ulcers on the inside of the nose or mouth. There are a variety of ways that cutaneous lupus rashes can appear. The distinctive rash is called the "butterfly rash," which is a rash that extends across the cheeks of the face and the bridge of the nose.
