What is a malar rash?
A malar rash is described as a skin rash that covers the bridge of the nose and some parts of the cheeks. It is also called as a butterfly rash and considered highly photosensitive and tends to turn dark red in color under sunlight.

This skin rash is also present in some arthritic conditions that have been triggered by viruses.
A petechial rash usually starts as flat and become elevated and then develops small-sized pinpoints of hemorrhage.
