Cutaneous Lupus (CLE) – Consultant Dermatologist Diagnosis & Treatment in London

Understanding cutaneous lupus

Cutaneous lupus erythematosus (CLE) is a form of lupus that primarily affects the skin. Unlike systemic lupus erythematosus (SLE), which can affect multiple organs, CLE manifests with rashes, scaling, or pigment changes confined to the skin. It occurs when the immune system mistakenly attacks the body’s own tissues, particularly after exposure to sunlight.

Types of cutaneous lupus

CLE can be classified into several subtypes:

• Discoid lupus erythematosus (DLE): Localised scaly plaques that may scar or cause hair loss if on the scalp.
• Subacute cutaneous lupus erythematosus (SCLE): Annular or psoriasiform rashes on sun-exposed areas.
• Acute cutaneous lupus: Butterfly-shaped rash across the cheeks and nose, often linked to systemic lupus.

Cutaneous Lupus Causes and risk factors

The exact cause is not fully understood, but genetic predisposition, immune dysregulation, and environmental triggers such as ultraviolet (UV) light play a role. Certain medications may also induce lupus-like rashes. Women, particularly those between 20 and 50, are more commonly affected.

Cutaneous Lupus Symptoms and signs

Typical features include:

• Red or purple patches on the face, scalp, or body.
• Rashes that worsen with sun exposure (photosensitivity).
• Scaling plaques that may scar after healing.
• Pigmentation changes, often more pronounced in darker skin tones.
• Hair loss if scalp lesions are present.

Cutaneous Lupus Diagnosis

Diagnosis involves a careful history, clinical examination, and sometimes skin biopsy. Blood tests may be carried out to check for systemic involvement. It is important to distinguish CLE from other inflammatory rashes such as psoriasis or eczema.

Cutaneous Lupus Treatment and management

Treatment is aimed at controlling inflammation, preventing flares, and minimising long-term skin damage. Options include:

• Sun protection: Daily use of broad-spectrum sunscreen and protective clothing.
• Topical corticosteroids or calcineurin inhibitors: To reduce inflammation.
• Antimalarial drugs: Hydroxychloroquine is often prescribed for persistent disease.
• Systemic immunosuppressants: Such as methotrexate or mycophenolate for resistant cases.
• Laser and scar management: For pigment changes or scarring.

Living with cutaneous lupus

CLE is a chronic condition with flares and remissions. Patient education and lifestyle adjustments are vital. Avoiding sun exposure, monitoring medications, and maintaining regular follow-up with a dermatologist help keep symptoms under control.

Special considerations

In patients with skin of colour, lupus lesions may heal with significant pigmentation changes, either darker or lighter than surrounding skin. Early diagnosis and treatment are crucial to prevent scarring alopecia when scalp involvement occurs.
