- Lupus erythematosus is divided into discoid lupus erythematosus and systemic lupus erythematosus.
- In the early stage of discoid lupus erythematosus, there will be one or several bright red spots on the surface of the patient's skin.
- Patients with systemic lupus erythematosus have multiple systemic manifestations at onset, and the symptoms are complex.
