What skin condition is associated with cutaneous lupus erythematosus?

The association of cutaneous lupus erythematosus with discoid lupus is well-established. Discoid lupus erythematosus is a specific form of cutaneous lupus characterized by round, disc-shaped lesions on the skin, often presenting with a red, scaly appearance. These lesions commonly occur on sun-exposed areas such as the face, scalp, and ears.

Discoid lupus can lead to scarring and pigmentation changes in the skin, which distinguishes it from other skin conditions. The presence of these distinctive lesions indicates an autoimmune process specifically linked to lupus. In contrast, the other options listed do not share this specific relationship with systemic lupus erythematosus or cutaneous lupus, as they represent separate dermatological conditions with different causes and manifestations.
