Malar rash
Malar Rash
Malar rash (pronunciation: /ˈmeɪlər ˈræʃ/), also known as the butterfly rash, is a medical symptom characterized by a red, flat, or raised area that covers the cheekbones and the bridge of the nose. The term "malar" comes from the Latin word "mala" which means "cheekbone".
Etymology
The term "malar" is derived from the Latin word "mala", which translates to "cheekbone". The term "rash" is derived from the Old French "rasche", meaning "eruption" or "scabies".
Symptoms
The primary symptom of a malar rash is a red or purplish skin discoloration that spreads across the cheeks and the bridge of the nose in a butterfly pattern. The rash may be flat or slightly raised and may feel warm to the touch. It can be painless or cause mild discomfort.
Causes
Malar rash is often associated with autoimmune diseases such as lupus, rosacea, and dermatomyositis. It can also be caused by certain infections, such as Lyme disease, or exposure to sunlight.
Diagnosis
Diagnosis of a malar rash is typically based on the characteristic appearance of the rash and the presence of other symptoms. Additional tests, such as blood tests or skin biopsies, may be performed to confirm the diagnosis and identify the underlying cause.
Treatment
Treatment for a malar rash depends on the underlying cause. This may include medications to reduce inflammation and manage the symptoms of the associated disease, as well as lifestyle changes to avoid triggers such as sunlight exposure.
