Navigating Lupus Skin Symptoms: From Rash to Lesions

Mirari Doctor

Lupus of the skin, also known as cutaneous lupus, is an autoimmune condition that causes various skin problems. When most people hear "lupus," they think of systemic lupus erythematosus (SLE), an autoimmune disease that can affect the whole body. But cutaneous lupus solely affects the skin. What is Cutaneous Lupus? Cutaneous lupus is a form of lupus that only affects the skin. With cutaneous lupus, the immune system mistakenly attacks healthy skin cells and tissues. This leads to skin rashes, lesions, and other problems. There are several main types of cutaneous lupus: Chronic cutaneous lupus: Long-lasting skin lesions in areas exposed to the sunSubacute cutaneous lupus: A bumpy, red rash on the upper body, arms, and faceAcute cutaneous lupus: A butterfly-shaped rash across the cheeks and noseDrug-induced cutaneous lupus: A lupus-like rash caused by certain medicationsAround 30% of people with SLE also develop some form of cutaneous lupus. But cutaneous lupus can occur on its own without systemic symptoms. Common Skin Problems in Cutaneous Lupus The most characteristic sign of lupus of the skin is a red, scaly rash on sun-exposed areas. Specific skin problems may include: Skin lesions: Red or purple raised patchesLupus rash: Butterfly rash on the face, disk-shaped facial rash, red bumpsPhotosensitivity: Increased reaction to UV light, easily sunburnedHair loss, mouth soresRaynaud's phenomenon: Fingers/toes turning white or blue in the coldVasculitis: Inflammation of blood vessels under the skinThe rashes and lesions of cutaneous lupus can cause itching, pain, scarring, and discoloration. Skin symptoms tend to flare periodically and improve at times. Cutaneous Lupus vs. SLE Rash Many people confuse cutaneous lupus with the malar rash of SLE. The "butterfly" rash across the cheeks and nose bridge is classic in SLE yet also occurs in some types of cutaneous lupus. Those with just cutaneous lupus typically don't progress to SLE's systemic symptoms. Read more: https://miraridoctor.com/blog/skin-lupus/
