From the archives:

Malar - relating to the cheek. From the Latin mala, cheek. The only remaining use for the word in anatomy is seen in "malar lymph nodes". The "cheek bone" was once called the malar, but the Terminologia Anatomica now only recognizes zygomatic bone.

Mala is probably derived from malus, Latin for apple; see the photo below for some evidence as to why apples and cheeks have been linked.

Definitely derived from malus is malic acid, first isolated in apple juice in the 18th century and responsible for the tart taste of apples, grapes, and rhubarb, among other foods.
