What Is Discoid Lupus?

Discoid lupus erythematosus (also called chronic cutaneous lupus), is a disease that affects the skin. It’s an autoimmune condition that occurs when your immune system malfunctions and mistakenly attacks your body.

The specific cause of discoid lupus is unknown. However, genetics, infections, and environmental factors are suspected for playing a role in autoimmune conditions.

Discoid Lupus Symptoms

The most common symptom of discoid lupus is red or purple round lesions (sores) on the skin, and these scaly lesions may cause pain or itching.

The most common locations for these lesions are your face, ears, and scalp, but they aren’t contagious. Like other forms of lupus, women of childbearing age are most commonly affected.

How a Dermatologist Can Help with Discoid Lupus

While discoid lupus isn’t curable, a dermatologist or rheumatologist can help you manage the condition with appropriate treatment. Medication therapy may include topical steroids as well as anti-inflammatory and immune-suppressing drugs.

Prompt treatment of this condition will help to minimize skin scarring, hair loss due to scalp scarring, and changes to the pigment of your skin. Quitting smoking can also help to minimize discoid flares since smoking can reduce the effectiveness of lupus medications.

How Sun Exposure Affects Discoid Lupus

Sun exposure can trigger lesions to erupt on the skin or cause existing lesions to worsen. Tanning beds and some indoor UV lighting can also contribute to skin eruptions.

In addition, some medications prescribed for treating discoid lupus may contribute to a more severe UV response. Avoiding UV radiation can help to minimize discoid lupus flares.

Discoid lupus lesions can raise your risk of skin cancer, and lip lesions require special attention due to a higher risk of squamous cell cancer. But you can help minimize your risk of discoid skin flares and skin cancer by significantly limiting your sun exposure.
