Lupus erythematosus is a disease in which the immune system mistakenly attacks the body's normal tissues and organs, causing inflammation and damage. It is a spectrum disorder that may affect one or multiple organs and systems. Lupus erythematosus can cause skin rashes, such as discoid lesions and butterfly-shaped facial rashes; it may also lead to systemic damage involving organs including the kidneys, heart, liver, brain, and lungs. The disease course is chronic and recurrent, ranging from the relatively benign chronic form—discoid lupus erythematosus—to subacute cutaneous lupus erythematosus, and severe systemic lupus erythematosus affecting multiple organs and systems. Various autoantibodies are typically detectable in the blood. Under medical supervision, medications such as hydroxychloroquine sulfate tablets, azathioprine tablets, methotrexate tablets, and mycophenolate mofetil capsules may be used to control the disease and alleviate symptoms.

Patients are advised to actively cooperate with their doctor's treatment plan to improve their condition and quality of life. Additionally, maintaining a positive mindset, avoiding exposure to ultraviolet radiation, and following a light, healthy diet can support recovery.
