Malar rash
Malar Rash[edit | edit source]
Overview[edit | edit source]
Malar rash, also known as "butterfly rash," is a medical condition characterized by an erythematous (red) eruption on the central face. This rash typically covers the cheeks and the bridge of the nose, often sparing the nasolabial folds. It is associated with a variety of conditions, ranging from skin disorders to systemic diseases.
Causes[edit | edit source]
Malar rash can be caused by several factors and conditions, including:
- Lupus erythematosus, particularly systemic lupus erythematosus (SLE)
- Rosacea
- Dermatomyositis
- Sun exposure
- Certain medications
- Infections
Symptoms and Characteristics[edit | edit source]
The rash is typically:
- Red or purplish
- Slightly raised
- Painful or itchy in some cases
- Symmetrical over the cheeks and nose
Diagnosis[edit | edit source]
Diagnosis of malar rash involves:
- Clinical examination of the facial skin
- Patient history analysis
- Laboratory tests if systemic lupus erythematosus or other connective tissue diseases are suspected
- Skin biopsy in uncertain cases
Treatment[edit | edit source]
Treatment depends on the underlying cause:
- For lupus-related rash: Corticosteroids or antimalarial medications like hydroxychloroquine
- For rosacea: Topical treatments and avoiding triggers
- For dermatomyositis: Corticosteroids and immunosuppressants
Prevention and Management[edit | edit source]
Preventive measures include:
- Sun protection with broad-spectrum sunscreen
- Avoiding known triggers
- Regular dermatological check-ups for those with chronic conditions
Prognosis[edit | edit source]
The prognosis of malar rash varies greatly depending on its underlying cause. Management of the primary disease often leads to improvement in the rash.
