Discoid lupus in children can be controlled, not cured, with standardized treatment. Discoid lupus erythematosus can be either pure cutaneous lupus erythematosus with skin involvement or systemic lupus erythematosus with skin damage. Most cases of discoid lupus erythematosus have a good prognosis if it is purely cutaneous lupus erythematosus with skin involvement; if it is systemic lupus erythematosus with skin manifestations and involvement of important organs such as nerves, kidneys and heart, the prognosis is poorer. In children, the prognosis of discoid lupus erythematosus with simple skin involvement is still good. However, if the skin is involved in SLE, the condition and treatment are generally more severe and difficult than in adults. If children have discoid lupus erythematosus, they should go to the pediatric rheumatology department of the hospital for follow-up and standardized diagnosis and treatment, and should not use medication on their own.
