Sign 3. Skin Rashes: The Telltale Butterfly Rash
Lupus is known for its characteristic skin manifestations, with the butterfly rash being one of the most iconic. This facial rash, medically known as malar rash, spreads across the cheeks and bridge of the nose, mimicking the shape of a butterfly in flight. It’s a visual clue that helps clinicians diagnose this autoimmune disease.
The butterfly rash, also known as acute cutaneous lupus, is a common early sign of lupus and affects approximately 50% of people with the condition. It can range in appearance from a faint blush to a more prominent, raised rash. The rash may be itchy or painful, but it’s crucial not to scratch it, as this can lead to scarring and skin infections.
The butterfly rash is more than just an unusual skin blemish. For many, it’s an alarming sign that something’s not right. It can appear suddenly or develop slowly over time, often accompanied by a general feeling of illness. This rash is usually flat or slightly raised, presenting as red or purple in color. It’s worth noting that the intensity of the rash can vary significantly from person to person, and it might worsen with exposure to sunlight, a symptom known as photosensitivity. (3)
