Malar Rash
Type: Symptom
Definition
A distinct, red, butterfly-shaped rash that spreads across the bridge of the nose and the cheeks.
Clinical Details
Immune complexes deposit directly into the dermal-epidermal junction of the skin, triggering severe localized inflammation. This characteristic rash frequently appears or significantly worsens following exposure to ultraviolet light from the sun. It is a classic visible diagnostic marker for this specific autoimmune condition.
