Xanthelasma

WHAT YOU SHOULD KNOW

A xanthelasma is a flat, yellowish growth on the outside of the eyelid, usually close to the nose. These noncancerous blemishes are composed of fatty material, and are usually a warning sign of high cholesterol levels.

Causes

We don't know what triggers these growths. However, they are typically associated with an elevated cholesterol level, especially when they are seen in teenagers and young adults.

Signs/Symptoms

Xanthelasmas are easy to spot, but cause no pain.

Care

Although some xanthelasmas disappear on their own, others persist and require removal by a physician. This is done by freezing the growths with liquid nitrogen, an extremely cold fluid that kills the fatty tissues. The procedure is usually performed in the office, and can be done by either a primary care physician or a dermatologist.

After the tissue has been removed, the doctor may send a sample to the lab for tests. If the xanthelasma proves to be evidence of an elevated cholesterol level, you will need to begin taking steps to lower your cholesterol immediately---among them, losing any excess weight and reducing the total amount of fat and cholesterol in your diet. If necessary, your physician may also prescribe a lipid-lowering drug such as Mevacor, Pravachol, or Zocor.

Risks

Although an underlying cholesterol problem can lead to heart disease if left unchecked, the xanthelasma itself poses no danger. It is typically removed only for cosmetic reasons. Even after removal, however, the growth may reappear.

WHAT YOU SHOULD DO

• Do NOT attempt to remove the growths with over-the-counter medications. Contact your physician to determine the exact nature of the growths and arrange for their removal. Your doctor can also check for the dangerously high cholesterol levels that the growths may signal.
• If you have the growths removed, follow your doctor's instructions for taking care of the area afterwards. Keep the area clean with soap and water and avoid applying make-up, creams, or lotions to the area.

Call Your Doctor If...

• The growths become red, swollen, or painful.
• After removal, the area begins to bleed.
