Malar rash, also called butterfly rash, is a medical sign consisting of a characteristic form of facial rash. It is often seen in Lupus erythematosus. Malar is the Latin for "cheek".

The malar rash of lupus is red or purplish and mildly scaly. Characteristically, it has the shape of a butterfly and involves the bridge of the nose.

Epidemiology and Demographics

A malar rash is present in approximately 46-65% of lupus sufferers and varies between different populations.^[1]^[2]^[3]

Diagnosis

Common Causes

There are numerous other conditions which can cause rashes with a similar appearance. Where lupus is suspected further medical tests (usually an ANA) and a detailed history are necessary to differentiate it from other conditions.
