Butterfly Rash: Causes, Symptoms and Diagnosis
The butterfly rash, a distinctive facial rash, is often associated with systemic lupus erythematosus (SLE), an autoimmune disease. This rash, also known as a malar rash, can be an indicator of underlying health issues, necessitating a comprehensive understanding of its causes, symptoms, and treatment options.
Here, we will delve into the complexities of the butterfly rash or malar rash, differentiating it from other dermatological conditions like rosacea, exploring its connection with lupus, and discussing the diagnostic and management strategies crucial for patients and healthcare providers.
What is a Butterfly Rash?
The butterfly rash is characterized by a red, inflamed, and often slightly raised rash that spans the bridge of the nose and extends symmetrically onto the cheeks, resembling a butterfly's wings. This distinct pattern makes it a telltale sign for diagnosing lupus, although it can also appear in other conditions.
Butterfly Rash vs. Rosacea
Understanding the differences between a malar rash and rosacea is vital for accurate diagnosis and treatment. While both conditions can present with facial redness, their underlying causes and presentations differ significantly.
- Butterfly Rash: Typically associated with lupus, it is often accompanied by other systemic symptoms such as joint pain, fatigue, and fever. The rash may be photosensitive, worsening with sun exposure.
- Rosacea: A chronic skin condition characterized by facial redness, visible blood vessels, and sometimes acne-like bumps. Unlike the butterfly rash, rosacea is not associated with systemic symptoms and primarily affects the skin.
Proper differentiation is essential as the management and treatment strategies for these conditions vary considerably.

Get Second OpinionKey Facts About the Butterfly Rash
The butterfly rash, also called a malar rash, is a distinctive skin condition that appears as a red or pink rash across the cheeks and nose, resembling the shape of a butterfly. This rash is most commonly associated with systemic lupus erythematosus (SLE), an autoimmune disease.
- Appearance: The rash spreads symmetrically across the bridge of the nose and cheeks. It may be flat or slightly raised and can sometimes be itchy or painful.
- Causes: The rash often flares up due to sun exposure, stress, or certain medications. In people with lupus, it is caused by the immune system attacking healthy skin cells.
- Who Gets It?: While anyone can develop a butterfly rash, it’s more common in individuals diagnosed with SLE butterfly rash and is often one of the early signs of lupus.
- The lupus butterfly rash is a hallmark symptom of SLE, helping in its diagnosis.
- It’s important to seek medical advice if you notice this rash, especially if it’s accompanied by other lupus symptoms like joint pain, fatigue, or fever.
Stages of Butterfly Rash
Early Stage
The early stage butterfly rash appears as mild redness or discoloration across the cheeks and the bridge of the nose.
- Rash is faint and may be mistaken for general skin irritation.
- Triggered by sun exposure or mild environmental factors.
- Usually painless and not accompanied by other symptoms.
Moderate Stage
In the moderate stage, the rash becomes more pronounced and may spread slightly.
- Redness intensifies, and the rash may feel warm or tender.
- Skin may appear slightly raised or flaky.
- More noticeable and harder to cover with makeup.
Severe Stage
The severe stage is characterized by significant inflammation and potential skin damage.
- Deep, persistent redness or darkened discoloration.
- Rash may crack, peel, or scar if untreated.
- Often associated with underlying conditions like lupus or thyroid issues.
Causes of Butterfly Rash
The butterfly rash primarily results from underlying autoimmune activity, most commonly linked to systemic lupus erythematosus. However, understanding the pathophysiological mechanisms can provide insight into its development and guide treatment options.
Lupus and Autoimmunity
Lupus is a chronic autoimmune disease where the immune system mistakenly attacks healthy tissues, leading to inflammation and damage. The precise cause of lupus is unknown, but it is believed to involve a combination of genetic, environmental, and hormonal factors. The butterfly rash emerges as a direct result of this autoimmune response, manifesting on the skin as the body mistakenly targets its own cells.
Environmental Triggers
While genetics play a significant role, environmental factors can trigger or exacerbate the appearance of the butterfly rash. Common triggers include:
- Sunlight Exposure: Ultraviolet (UV) light is a well-known trigger for lupus rashes, including the malar rash. Patients often notice a flare-up of symptoms following sun exposure.
- Stress: Both physical and emotional stress can exacerbate lupus symptoms, including skin manifestations.
- Infections: Certain infections can trigger or worsen lupus symptoms, contributing to the onset of a malar rash.
Symptoms of Butterfly Rash
Common Malar Rash of Butterfly Rash Symptoms
- A butterfly-shaped rash across the cheeks and nose.
- Redness, inflammation, or discoloration.
- Skin sensitivity, particularly to sunlight.
Early Stage Malar Rash Symptoms
- Faint redness or pinkish discoloration.
- Slight warmth or tenderness on the affected area.
- Minimal or no itching.
Advanced Stage Malar Rash Symptoms
- Intense redness, often scaly or flaky.
- Burning, itching, or pain in the rash area.
- Potential scarring or discoloration after healing.
If symptoms worsen or involve a butterfly rash on a child’s face, or if linked to conditions like thyroid butterfly rash, seek medical advice promptly.
Diagnosing Butterfly Rash
Accurate diagnosis of a butterfly rash requires a comprehensive evaluation by healthcare professionals, taking into account the patient's medical history, clinical presentation, and laboratory findings.
Clinical Examination
A thorough clinical examination is crucial for distinguishing a malar rash from other skin conditions. Dermatologists and rheumatologists often work in tandem to assess the rash's characteristics, distribution, and associated symptoms.
Laboratory Tests
Laboratory tests are integral to confirming a diagnosis of lupus in patients presenting with a butterfly rash. Common tests include:
- Antinuclear Antibody (ANA) Test: Detects the presence of antibodies that attack the body's own tissues, a hallmark of autoimmune activity in lupus.
- Complete Blood Count (CBC): Evaluates overall health and detects a range of disorders, including anemia and infection, which can accompany lupus.
- Erythrocyte Sedimentation Rate (ESR): Measures inflammation levels in the body, often elevated in lupus patients.
Skin Biopsy
In some cases, a skin biopsy may be performed to rule out other dermatological conditions and confirm a diagnosis of lupus. The biopsy involves taking a small sample of skin tissue for microscopic examination.
Butterfly Rash Treatment
Butterflies rash treatment involves treating the underlying cause, e.g. lupus or some other autoimmune condition, and managing symptoms. Treatment will depend on the severity of your rash, but doctors often prescribe a combination of medications, skincare changes, and preventative care.
Medical Treatments for Butterfly Rash
- Topical Medications: Corticosteroid creams may help lessen inflammation and redness. If necessary, your doctor might prescribe more potent creams.
- Medications by mouth: In more extreme situations, medication for butterfly rash like hydroxychloroquine (generally used for lupus) can help restrain the immunological response and extreme incidences.
- Antihistamines: These may be helpful for relief if the rash is itchy or is the result of an allergic reaction.
Lifestyle and Prevention Tips
- Saving Your Skin: Use sunscreen with SPF 30 or higher every day to prevent sun-induced flare-ups.
- Gentle Skin Care Routine: Skip harsh soaps and exfoliants that can irritate sensitive skin.
- Diet: Eat an anti-inflammatory diet, rich in foods like leafy greens, fish, and berries, to reduce inflammation and support skin health.
- Monitor Triggers: You can keep a diary to look for and avoid specific triggers, like stress or certain medications.
