Discoid Lupus: Symptoms, Management, and What You Need to Know

When you see a persistent, red, scaly patch on your face, scalp, or ears that won’t go away, it might not be just a bad rash—it could be discoid lupus, a chronic autoimmune skin disorder that causes distinct, coin-shaped lesions. Also known as cutaneous lupus erythematosus, it’s the most common form of lupus that stays limited to the skin, but it can sometimes signal a deeper issue. Unlike systemic lupus, which affects organs like the kidneys or heart, discoid lupus usually stays on the surface—but that doesn’t mean it’s harmless. Left untreated, those patches can scar, change skin color, and even cause hair loss if they appear on the scalp.

Many people confuse discoid lupus with eczema or psoriasis, but the key difference is in the texture and behavior. Discoid lesions are thick, raised, and often have a white, flaky center with dark borders. They don’t itch as much as eczema, but they burn or sting in the sun. Sun exposure is one of the biggest triggers, which is why people with this condition often notice flare-ups after outdoor activities—even on cloudy days. systemic lupus, a more widespread autoimmune disease that can involve multiple organs shares some genetic and immune triggers with discoid lupus, and about 5-10% of people with discoid lupus eventually develop systemic lupus. That’s why monitoring symptoms over time matters.

There’s no cure, but discoid lupus is highly manageable. Topical steroids, antimalarial drugs like hydroxychloroquine, and strict sun protection can keep lesions under control. Many patients see improvement within weeks if they avoid UV light and stick to their treatment plan. You’ll also want to watch for signs of infection in open sores or sudden swelling, which could mean something else is going on.
