Xanthoma is defined as a skin condition in which certain fats pile up under the surface of your skin.
From small growths to ones bigger than three inches, xanthomas can vary in size, The Mount Sinai Health System reports.
When it comes to the location of these growths, they might pop up anywhere on your body.
But they are “most often” seen on the elbows, joints, tendons, knees, hands, feet, or buttocks.
