Quick Answer
Discoid lupus is the most common type of cutaneous (skin) lupus, causing round, coin-shaped sores, usually on the face and scalp, that may be scaly or red and can scar. [1] Women aged 15–44, especially Black women, are at highest risk. [1] There is no cure, but treatment helps about 60% of people, [1] and daily sun protection prevents flare-ups.
What the research says
Progression to severe systemic lupus is uncommon and can be predicted. In a registry-based cohort of 164 people with discoid lupus (30 later developed severe systemic lupus), three factors were linked to progression: age under 25 at diagnosis (odds ratio 2.8), darker skin phototype V to VI (odds ratio 2.7) and antinuclear antibody titers of 1:320 or higher (odds ratio 15). None of the 54 patients with a baseline score of 0 progressed, while a score of 6 or more carried a risk of about 40%; the study was retrospective (Fredeau et al., Journal of the American Academy of Dermatology, 2023) [4].
Treatment evidence is moderate, and high-quality trials are scarce. A systematic review of 107 studies covering 7,343 patients found moderate evidence for topical calcineurin inhibitors (especially on facial skin, as a steroid-sparing option) and for hydroxychloroquine, moderate evidence for thalidomide but with significant toxicity risk, and moderate data for belimumab. It also recommended general measures such as sun protection, smoking cessation and optimizing vitamin D levels (Fairley et al., Seminars in Arthritis and Rheumatism, 2020) [5].
Photosensitivity is common, and many patients don't know how to protect themselves. In an international survey of 600 people with lupus erythematosus (cutaneous lupus and systemic lupus) from 50 countries, 64.8% reported a history of photosensitivity. Although 93% knew UV exposure is harmful, 33.3% (160 of 480) were unaware of the importance of photoprotective measures (Battesti et al., Rheumatology, 2024) [6].
What is discoid lupus?
Discoid lupus erythematosus (DLE) is a type of cutaneous lupus erythematosus (CLE). Cutaneous refers to skin. CLE includes types of lupus that affect your skin. People with discoid lupus get round sores, usually on their face or scalp. Another name for discoid lupus is chronic cutaneous lupus. [1]
What is lupus?
What most people call lupus is systemic lupus erythematosus (SLE). SLE is the most common type of lupus: about 70% of people who have lupus have SLE. [1] SLE causes widespread inflammation in your body.
People with lupus often have chest pain, fatigue, fever, joint pain or swelling, rashes or other skin symptoms, and sensitivity to light (photosensitivity).
What are the types of cutaneous lupus erythematosus?
There are three types of CLE, and each type causes a different skin rash.
Type | The rash it causes | Typical locations |
Discoid lupus | Circular patches of thick, inflamed skin | Ears, cheeks or nose (round sores usually on face or scalp) |
Subacute cutaneous lupus | Ring-shaped or scaly rashes | Back, chest or neck |
Acute cutaneous lupus | “Butterfly rash” that looks like a sunburn | Across the cheeks and nose |
Can you have more than one kind of lupus?
Some people only have SLE, CLE or another type of lupus. Others have multiple types of lupus. Most people who have discoid lupus do not have another type of lupus.
Only about 5% of people with discoid lupus also develop SLE. [1] About one in four people with SLE develop lesions that look like discoid lesions. [1]
How common is discoid lupus?
About two out of every three people who have systemic lupus also have symptoms of cutaneous lupus. [1] Discoid lupus is the most common type of CLE. [1]
What causes discoid lupus?
Experts don't know what causes lupus, including discoid lupus. Lupus and other autoimmune diseases tend to run in families. [1]
Who is most likely to have discoid lupus?
You have a higher risk for developing chronic cutaneous lupus if you are female; age 15 to 44, with women in their 30s and 40s most commonly affected; or Black (with risk up to four times higher in Black women than in white women), Asian American, Hispanic/Latino or Native American. [1]
Risk factor | Detail |
Sex | Female |
Age | 15 to 44; women in their 30s and 40s most commonly affected |
Race/ethnicity | Black (up to four times higher risk in Black women than white women), Asian American, Hispanic/Latino or Native American |
Family history | Lupus and other autoimmune diseases tend to run in families |
What are the symptoms of discoid lupus?
Discoid lupus causes round, coin-shaped lesions (sores). The sores most commonly develop on your scalp and face, but they may show up on other parts of your body. Discoid lesions typically do not hurt or itch. They may be scaly, thick or red. When the lesions go away, they may leave scars or skin discoloration. [1]
Symptom feature | What you will see or feel |
Shape | Round, coin-shaped lesions (sores) |
Location | Most commonly scalp and face; may appear on other body parts |
Texture | May be scaly, thick or red |
Pain/itch | Typically do not hurt or itch |
After healing | May leave scars or skin discoloration |
What are the complications of discoid lupus?
If a discoid lupus rash occurs on your scalp, it may cause hair loss. If a scar forms on your scalp, the hair loss may be permanent. [1] Having a discoid rash that lasts a long time may increase your risk for skin cancer. Discoid sores inside your mouth can increase your risk for a type of skin cancer called squamous cell carcinoma. [1]
Rarely, people may develop chilblain lupus erythematosus. Chilblain lupus causes purple skin patches or lesions that worsen after exposure to cold temperatures. [1] These lesions are often very painful.
Complication | What it means |
Scalp hair loss | A scalp rash may cause hair loss; scarring can make it permanent |
Skin cancer risk | A long-lasting discoid rash increases skin cancer risk |
Mouth sores | Discoid sores inside the mouth increase the risk of squamous cell carcinoma |
Chilblain lupus (rare) | Purple patches or lesions that worsen after cold exposure; often very painful |
How is discoid lupus diagnosed?
A dermatologist (skin care doctor) may diagnose discoid lupus. Usually, the dermatologist uses a test called a biopsy. [1] During a biopsy, your dermatologist takes a small skin sample. The provider sends the skin sample to a laboratory, where specialists examine it under a microscope. Looking at the skin sample under a microscope can tell healthcare providers whether skin sores are due to discoid lupus or another condition.
How is discoid lupus treated?
Depending on how severe your symptoms are, your healthcare provider may recommend medications. These medications can reduce discoid lupus symptoms. Some research suggests that medications are helpful for about 60% of people with cutaneous lupus. [1]
Medication class | Examples | What it does |
Steroid ointments | Fluocinolone acetonide (topical steroid cream) or hydrocortisone butyrate (topical steroid cream) | Lower inflammation and decrease swelling |
Anti-inflammatory drugs | Dapsone or low-dose methotrexate | Reduce pain and swelling |
Antimalarial drugs | Hydroxychloroquine | Fight fatigue, reduce rashes and decrease joint pain |
Calcineurin inhibitors | Tacrolimus or pimecrolimus (topical) | Decrease inflammation by suppressing your immune system |
How can I prevent discoid lupus symptom flare-ups?
In up to 70% of people who have CLE, their symptoms worsen after exposure to ultraviolet (UV) light. [1] If you have lupus, you need to take extra caution around UV rays.
UV protection step | Detail |
Sunscreen | Apply broad-spectrum sunscreen with at least SPF 30 daily; reapply every four hours |
Timing | Avoid sunlight when rays are strongest, between 10 a.m. and 4 p.m. |
Indoor light | Limit your time under indoor fluorescent lights |
Tanning beds | Don't use them at all |
Clothing | Wear sun-protective clothing, such as long sleeves and wide-brimmed hats |
What is the outlook for people with discoid lupus?
Lupus is a lifelong condition. With treatment, many people with discoid lupus experience symptom relief. Taking precautions around UV rays can keep symptoms from worsening.
How can I prevent discoid lupus?
There is no way to prevent lupus. If you have discoid lupus, you can manage symptoms by avoiding sun exposure. To reduce chances of infection and scarring, you should avoid scratching or picking at sores. [1]
What else should I ask my doctor?
You may also want to ask your healthcare provider how you can avoid developing discoid rashes, what you should do to treat a discoid rash, what the warning signs are that discoid lupus is not well-controlled, and what the early warning signs of skin cancer are.
“Discoid lupus is the most common type of lupus that affects your skin. People with discoid lupus typically develop round skin lesions. These lesions usually are not painful, but they can increase your risk for skin cancer. To prevent discoid lupus lesions, limit your exposure to ultraviolet (UV) light. There is no cure for discoid lupus, but treatment can help you manage symptoms and avoid flare-ups.” — Cleveland Clinic
When should I see my healthcare provider?
See your provider if you develop round, coin-shaped sores on your face or scalp; if a lesion leaves scarring or permanent hair loss on your scalp; if sores appear inside your mouth; or to learn the early warning signs of skin cancer so you can be monitored for the increased risk that long-lasting discoid sores create.
The Bottom Line: What You Need to Know About Discoid Lupus
Discoid lupus is the most common form of lupus that affects the skin. It produces round, coin-shaped sores that usually appear on the face and scalp. They typically don't hurt or itch but can be scaly, thick or red, and may leave scars or discoloration once they heal. The cause is unknown, though it runs in families, and women between 15 and 44, especially Black women, who face up to four times the risk of white women, are most often affected.
The most important fact for daily life is UV light. In up to 70% of people with cutaneous lupus, symptoms worsen after UV exposure. [1] That makes SPF 30+ sunscreen reapplied every four hours, avoiding the 10 a.m.–4 p.m. sun, no tanning beds, and protective clothing the daily toolkit for preventing flare-ups.
Treatment helps about 60% of people with cutaneous lupus, using steroid ointments, anti-inflammatory drugs, antimalarial drugs and calcineurin inhibitors. There is no cure, but many people achieve symptom relief, and only about 5% of people with discoid lupus ever develop the systemic form. [1] The serious caveat is skin cancer risk: long-lasting sores, especially inside the mouth, raise the risk of squamous cell carcinoma, and scalp sores can scar and cause permanent hair loss. Protect your skin, don't pick at sores, and see your provider for monitoring.
Take the first step. Start wearing SPF 30+ sunscreen every day, avoid peak sun hours and tanning beds, treat rashes early rather than waiting, and ask your dermatologist about biopsy confirmation and the early warning signs of skin cancer.
