How is discoid lupus diagnosed?
The diagnosis of discoid lupus is based on your symptoms and physical examination. Your doctor may also recommend a biopsy, which is a procedure to remove a small piece of skin to be examined under a microscope. A biopsy can help confirm the diagnosis of discoid lupus.
How is discoid lupus treated?
There is no cure for discoid lupus, but treatment can help reduce inflammation and improve symptoms. Treatment for discoid lupus may include:
- topical and oral corticosteroids
- antimalarial medication
- immunosuppressive drugs
Most people with discoid lupus have a good prognosis and go into remission after treatment. However, discoid lupus can come back, and some people may develop systemic lupus erythematosus (SLE), which is a more serious form of the disease. If you have discoid lupus, it is important to see your doctor for regular checkups and to report any new symptoms.
