Picture of Acute Systemic Lupus
Acute systemic lupus erythematosus is an autoimmune condition that often causes a characteristic, butterfly pattern rash on the face. The red to purple rash appears across the cheeks and over the bridge of the nose. This malar rash, as it is called, may be blotchy or completely cover the face.
