Cutaneous Lupus Erythematosus (CLE)
Cutaneous Lupus Erythematosus (CLE) is a form of lupus that primarily affects the skin. It is an autoimmune condition where the immune system mistakenly attacks healthy skin cells, leading to inflammation, rashes, and potential scarring. Unlike Systemic Lupus Erythematosus (SLE), which can affect multiple organs, CLE is generally confined to the skin, though some cases may be associated with systemic involvement.

Types of Cutaneous Lupus Erythematosus
CLE is categorized into three main subtypes:
Chronic Cutaneous Lupus Erythematosus (CCLE) – Discoid Lupus Erythematosus (DLE)
The most common form of CLE, DLE manifests as round, red, scaly patches that often appear on the face, scalp, and ears.
Over time, lesions may lead to scarring and permanent hair loss if they occur on the scalp.
These lesions can be photosensitive, worsening with sun exposure.
Subacute Cutaneous Lupus Erythematosus (SCLE)
SCLE is characterized by red, ring-shaped or scaly skin lesions that typically appear on sun-exposed areas such as the arms, shoulders, and neck.
Unlike DLE, SCLE lesions usually do not cause scarring but may leave skin discoloration.
This form is strongly linked to sun exposure and can be triggered by certain medications.
Acute Cutaneous Lupus Erythematosus (ACLE)
Often associated with systemic lupus, ACLE presents as a distinctive butterfly-shaped rash across the cheeks and nose (malar rash).
This rash can appear after sun exposure and is a common symptom in patients with SLE.
Causes and Risk Factors
The exact cause of CLE is unknown, but several factors contribute to its development, including:
Genetic predisposition – A family history of lupus increases the likelihood of developing CLE.
Sun exposure – Ultraviolet (UV) light is a major trigger for CLE flare-ups.
Hormonal factors – Women, especially of childbearing age, are more prone to developing CLE.
Certain medications – Some drugs, such as antihypertensives and antifungals, have been linked to CLE-like reactions.
Diagnosis
A dermatologist or rheumatologist may diagnose CLE through:
Physical examination – Evaluating skin lesions and their distribution.
Skin biopsy – A small sample of affected skin is examined under a microscope to confirm CLE.
Blood tests – Checking for autoantibodies, such as antinuclear antibodies (ANA), which may indicate lupus involvement.

Treatment and Management
Although there is no cure for CLE, treatments focus on controlling symptoms and preventing flare-ups:
Topical corticosteroids – Reduce inflammation and help heal lesions.
Antimalarial drugs (e.g., hydroxychloroquine) – Often used to manage CLE, particularly SCLE and DLE.
Immunosuppressive medications – Used in severe cases to control immune system overactivity.
Sun protection – Avoiding sun exposure, wearing protective clothing, and using high-SPF sunscreen can help prevent flare-ups.
Living with Cutaneous Lupus
Managing CLE requires a proactive approach, including regular dermatological checkups, lifestyle adjustments, and adherence to treatment plans. By taking necessary precautions, individuals with CLE can effectively control symptoms and improve their quality of life.
Conclusion
Cutaneous Lupus Erythematosus is a complex autoimmune skin disorder with different subtypes, each requiring specific management strategies. Early diagnosis and treatment are key to preventing complications and ensuring optimal skin health. With the right care and preventive measures, many people with CLE can lead fulfilling lives while managing their condition effectively.
