Cutaneous lupus refers to a group of autoimmune skin conditions marked by redness, inflammation, and photosensitive rashes or plaques. It may occur as an isolated disorder or alongside systemic lupus.
The condition presents in several patterns:
- Acute cutaneous lupus: Best known for the classic “butterfly” rash across the cheeks and nose.
- Subacute cutaneous lupus: Appears as red, ring-shaped or scaly plaques, most often on the trunk and limbs.
- Chronic discoid lupus: Produces thickened, indented red-and-white patches, usually affecting the scalp, face, or neck.
Genetic susceptibility, environmental influences—especially ultraviolet (UV) light—and certain medications can all play a role in triggering or worsening symptoms. The disease often follows a relapsing course, with alternating periods of flares and remission.
Management emphasizes accurate diagnosis, sun protection, identification of potential triggers, and individualized therapies aimed at reducing inflammation and maintaining long-term skin health.
Signs & Symptoms
- From a butterfly-pattern facial rash to ring-shaped plaques or thickened discoid patches that may scar or alter pigment if untreated.
- Sun-exposed areas (face, scalp, neck, chest, arms) are the most common areas affected by lupus.
- May be asymptomatic or cause itching, tenderness, or stinging; sunlight typically worsens activity.
- Flares can be triggered by UV exposure, illness, stress, or medications. Activity may wax and wane over time.
Causes & Risk Factors
- Autoimmune activity targeting skin structures
- UV exposure and photosensitivity
- Genetic predisposition or family history of autoimmune disease
- Medication triggers in select cases
Treatment Options
- Topical prescriptions to reduce inflammation (e.g., steroid or non-steroidal anti-inflammatory creams/ointments).
- Oral therapies for more extensive disease (such as immunomodulating or anti-inflammatory medications).
- Photoprotection & trigger management: daily broad-spectrum SPF, UV-protective clothing, and review of potential medication or lifestyle triggers.
