Which symptom is associated with skin involvement in SLE?

Discoid lesions are a hallmark manifestation of skin involvement in systemic lupus erythematosus (SLE). These lesions are circular, red, and scaly patches that can appear on various areas of the skin, particularly on the face and scalp. They are characterized by their raised edges and a central clearing, which can lead to scarring in some cases. Discoid lupus erythematosus, specifically, is a form of cutaneous lupus that can occur independently or as part of the systemic disease.

In contrast, the other options do not specifically relate to SLE. Acne is primarily a dermatological condition caused by factors such as hormonal changes and is not associated with autoimmune processes. Skin tags are benign growths that can occur for various reasons, often linked to friction and skin conditions but not specifically with SLE. Wrinkles are a natural part of aging and skin changes over time and do not serve as a symptom or manifestation of SLE. Thus, discoid lesions are the correct answer when identifying a symptom specifically associated with skin involvement in systemic lupus erythematosus.
