Detailed explanation-1: -Lupus causes various rashes on your face and body. A butterfly-shaped (malar) face rash is a common sign of the disease. Discoid lupus, a type of cutaneous lupus, causes circular red rashes on your body.

Detailed explanation-2: -What Causes a Malar Rash? Of the malar rash causes, the most common is rosacea, a skin condition that is not connected with a systemic disease. A rash from rosacea is red with small bumps and tiny broken blood vessels. It is most common in fair-skinned people.

Detailed explanation-3: -Malar rash, also named a butterfly rash, is a common facial presentation of multiple disorders. It is characterized by an erythematous flat or raised rash across the bridge of the nose and cheeks, which usually spares nasolabial folds. It may be transient or progress to involve other areas of facial skin.

Detailed explanation-4: -Is a butterfly rash a definite indicator of lupus or can you have a butterfly rash and not have lupus? While the butterfly rash (also called a malar rash or lupus rash) is one of the most commonly known symptoms people associate with lupus, it does not need to be present to be diagnosed with lupus.
