Malar flush is a plum-red discolouration of the high cheeks.[1]
It is classically associated with mitral valve stenosis due to the resulting CO2 retention and its vasodilatory effects.[1] It can also be associated with lupus, polycythemia vera and homocystinuria.
Definition
Malar flush is a plum-red discolouration of the high cheeks.[1]
Pathophysiology
Mitral valve stenosis may cause malar flush due to CO2 retention, which causes vasodilation of arterioles in the cheeks.[1]
It can also be associated with other conditions, such as lupus,[2] polycythemia vera[3] and homocystinuria.[4]
