Discoid lupus, a type of cutaneous lupus, gets its name from the round, “coin-like” rash it causes. While lupus rashes can occur anywhere on the body, most people with the condition develop them on the face or scalp.

Managing discoid lupus can be challenging, especially when symptoms appear on visible areas of the skin. There’s no specific cure, but there are things you can do to make living with the condition easier.

In this article, we deep dive into everything you need to know about discoid lupus, covering what it is, the most common symptoms, and effective ways to manage it.

Let’s get into it.

Understanding the different types of lupus

The most common and well-known type of lupus is systemic lupus erythematosus (SLE). It causes symptoms and inflammation throughout the body.

Smaller subtypes cause different symptoms. Cutaneous lupus is one of the more well-known subtypes, and it primarily impacts the skin.

Within the category of cutaneous lupus, there are additional subtypes:

Subacute cutaneous lupus

Subacute cutaneous lupus (SCLE) is characterized by a red, ring-like rash that appears on areas of the body that are exposed to the sun, like the back, chest, and arms. It can also impact the face or scalp, but this is rare.

This subtype doesn’t usually leave permanent scars, but it can cause skin discoloration.

Sun exposure is a common trigger, but SCLE can also be associated with certain medications. In some cases, symptoms may appear months or years after starting a drug, so it can be useful to track new or changing skin symptoms alongside medication changes.

Acute cutaneous lupus

Acute cutaneous lupus is characterized by a rash, which develops alongside systemic lupus symptoms.

It typically comes on quickly and doesn’t last for long. It doesn’t usually leave permanent scarring, although it can cause skin discoloration.

Acute cutaneous lupus can be either localized or generalized. The malar “butterfly” rash is a localized form that appears on the face (across the cheeks and bridge of the nose). Generalized forms can cause raised red rashes across the body.

Chronic cutaneous lupus

Two characteristics of chronic cutaneous lupus set it apart:

• It can last for long periods.
• It can leave permanent scarring.

Discoid lupus is the most common type of chronic cutaneous lupus. The rest of this article dives deeper into this subtype.

What is discoid lupus?

Discoid lupus is also known as chronic cutaneous (skin) lupus or discoid lupus erythematosus. It’s the most common type of cutaneous lupus and causes a very specific type of skin rash.

Like other autoimmune conditions, discoid lupus symptoms often fall into “flare” patterns. When a flare occurs, the immune system becomes overactive and attacks the skin, causing symptoms.

Flares can last anywhere from a few days to months. When a flare finishes, a period of remission begins. During a period of remission, you might not experience symptoms. If you do, they may be mild.

Discoid lupus symptoms

Discoid lupus primarily impacts the skin, causing a rash with the following typical characteristics:

• Round or coin-shaped
• Well-defined edges
• Thickened skin
• Red-to-purple in color, depending on skin tone

Most people with discoid lupus notice the rash on their face and scalp. Over time, it can result in scarring, changes in skin color, and permanent hair loss if hair follicles are damaged.

Symptoms can vary. Some people experience little to no discomfort, while others may notice itching, tenderness, or sensitivity in affected areas.

Diagnosing discoid lupus

The diagnostic process usually starts with your doctor examining an active rash and asking some screening questions (such as “How long have you had this rash?” or “Does it feel itchy or painful?”).

Your doctor will determine whether you need to see a dermatologist, who will likely perform a skin biopsy. During a skin biopsy, the doctor will:

• Remove a small section of your skin affected by the rash (under local anesthesia)
• Send the sample to the lab for analysis
• Determine if the sample shows signs of discoid lupus

How to manage discoid lupus

Currently, there is no cure for discoid lupus. As a result, the primary goal of treatment is to manage and reduce the severity and frequency of flares.

Below are some of the most common medications for discoid lupus.

Topical treatments

Corticosteroids: A first-line treatment option for discoid lupus applied directly to the affected areas to help reduce inflammation and decrease swelling during a flare.

Examples include:

• Fluocinonide 0.05% ointment
• Hydrocortisone 1% cream

Calcineurin inhibitors: Effective for managing discoid lupus symptoms, especially if the skin is damaged by ongoing corticosteroid use.

Examples include:

• Pimecrolimus 1% cream
• Tacrolimus 0.03% ointment
• Tacrolimus 0.1% ointment

Antimalarials

Antimalarials are first-line therapy for cutaneous lupus, including discoid lupus. They work by modulating the immune system and reducing inflammation.

Hydroxychloroquine is generally preferred due to its lower risk of side effects compared to alternatives such as chloroquine.

These medications take time to work. It can take several weeks before you notice improvements, and your doctor will likely assess how your body is responding after a period of continued use.

NSAIDs

During periods of remission and flares, taking oral non-steroidal anti-inflammatory drugs (NSAIDs) can help reduce inflammation and pain associated with discoid lupus.

Examples include: 

• Ibuprofen Advil®, Motrin®)
• Naproxen (Aleve®, Naprosyn®)
• Indomethacin (Indocin®)
• Nabumetone (Relafen®)
• Celecoxib (Celebrex®)
• Aspirin

Important note: While many NSAIDs are available over the counter, you should not start taking them for your discoid lupus symptoms without consulting your doctor first.

Preventing discoid lupus flares

Reducing your risk of flares is essential for improving your quality of life while living with discoid lupus.

Sun exposure can play a role in the development or worsening of some rashes, although not everyone will notice a clear link. Over time, repeated skin damage in affected areas can increase the risk of complications, including skin cancer.

While there’s no definitive list of discoid lupus triggers, your doctor may recommend:

• Avoiding direct UV exposure
• Wearing a minimum of SPF 30 sunscreen every day, reapplying every four hours
• Avoiding outdoor activities during peak UV times (10 am to 4 pm)
• Not using indoor tanning beds
• Wearing sun-protecting clothing

Smoking can make discoid lupus symptoms harder to manage and may affect how well treatments work. Cutting down or stopping, if you’re able to, can help make living with the condition easier.

Important note: Discoid lupus affects people differently. Keeping a symptom journal of your flares, sun exposure, and medication use can help create a comprehensive health map to share with your provider.

Track your skin symptoms

While discoid lupus is generally not life-threatening, living with any visible skin condition can be difficult, especially when rashes affect areas like the face or scalp. Symptoms can change over time, and flares are not always predictable.

Using the Human Health app, you can log rash severity, location, and possible triggers over time, giving you a clearer picture of your health. It’s an effective way to investigate and manage your own condition, creating a health map you can share with your doctor to get the best possible care.

Frequently asked questions

How serious is discoid lupus?

Discoid lupus is not considered life-threatening, and people with this condition have a low risk of developing potentially dangerous complications. However, the effects, like permanent scarring and hair loss, can be challenging. That’s why careful management and tracking are so important.

What does discoid lupus look like?

Discoid lupus gets its name from the “disc-like” patches of skin it causes.

In most people, areas affected by discoid lupus present with red-to-purple patches of thick, scaly skin. For some, sun exposure can trigger or worsen discoid lupus rashes.

Does discoid lupus cause hair loss?

Discoid lupus can cause hair loss in some cases. Because discoid lupus can cause patches of thick purplish-red skin on the scalp, it can temporarily or permanently impact hair growth.

Early diagnosis and effective management are the best ways to reduce serious unwanted side effects, including hair loss.
