Xanthoma is a skin condition in which certain fats build up under the surface of the skin.
Skin growths - fatty; Xanthelasma
Xanthomas are common, especially among older adults and people with high blood lipids (fats). Xanthomas vary in size. Some are very small. Others are bigger than 3 inches (7.5 centimeters) in diameter. They may appear anywhere on the body. But, they are most often seen on the elbows, joints, tendons, knees, hands, feet, or buttocks.
Xanthomas may be a sign of a medical condition that involves an increase in blood lipids. Such conditions include:
Xanthelasma palpebra is a common type of xanthoma that appears on the eyelids. It usually occurs without any underlying medical condition.
A xanthoma looks like a yellow to orange bump (papule) with defined borders. There may be several individual ones or they may form clusters.
If you have a disease that causes increased blood lipids, treating the condition may help reduce the development of xanthomas.
If the growth bothers you, your provider may remove it by surgery or with a laser. However, xanthomas may come back after surgery.
