What type of lupus is primarily characterized by skin symptoms?

Discoid lupus is primarily characterized by skin symptoms. This form of lupus, also known as discoid lupus erythematosus, manifests mainly through chronic skin lesions that can appear as disc-shaped, raised, red patches with scaling, which can lead to scarring or changes in skin pigmentation if not treated effectively. While systemic lupus erythematosus involves various organ systems and presents with a broader range of symptoms beyond the skin, discoid lupus is localized to the integumentary system, making it distinct for those focusing specifically on dermatological manifestations.

In cases of drug-induced lupus, symptoms may also include skin rashes, but this type of lupus is associated with specific medications and typically resolves after discontinuation of the drug, rather than being primarily a skin condition. Neonatal lupus is a condition affecting infants born to mothers with lupus, characterized by skin rashes and other symptoms but is not a form of lupus that primarily presents with skin symptoms in the same manner as discoid lupus. Therefore, discoid lupus stands out as the correct answer due to its specific focus on skin-related issues.
