What is Xanthelasma?

Xanthelasma are yellowish fatty deposits that form under the skin, usually on or around the eyelids. They develop as a result of cholesterol buildup and can appear soft, firm, or semi-solid in structure. These cholesterol deposits beneath the skin surface create yellow patches, which may appear flat or slightly raised as soft nodules or papules. They are most commonly seen on the eyelids, inner corners of the eyes, or areas closer to the nose.

Xanthelasma often develops symmetrically around both eyes. While they may remain the same size for a long time, in some cases they gradually enlarge and merge, forming bigger lesions.

Although usually harmless, xanthelasma can be removed through surgical or non-surgical methods. They may also indicate underlying health issues such as diabetes, hyperlipidemia (high cholesterol), or thyroid disorders.

Causes of Xanthelasma

Xanthelasma can occur at any age due to genetic predisposition, high cholesterol, or certain medications. However, it is most frequently seen in middle-aged and older adults, with a higher prevalence in women.

Main factors that contribute to xanthelasma include:

Hyperlipidemia:
Excessive fat (lipid) levels in the bloodstream, especially triglycerides and cholesterol, are one of the most common causes. These fats can also accumulate in arteries, increasing the risk of heart disease and stroke.

Genetic factors:
Inherited lipid disorders, such as familial hypercholesterolemia, hypertriglyceridemia, or lipoprotein lipase deficiency, can lead to cholesterol deposits around the eyes.

Lifestyle habits:
An unhealthy diet rich in saturated and trans fats, smoking, excessive alcohol use, obesity, and lack of exercise can increase the risk of xanthelasma.

Medications:
Certain medications may trigger lipid buildup around the eyes, including tamoxifen, oral retinoids, cyclosporine (used in transplant patients), protease inhibitors (HIV/AIDS treatment), and estrogen-based drugs.

Xanthelasma patients have a higher likelihood of developing cardiovascular diseases in the future, such as heart attack, atherosclerosis (even with normal cholesterol levels), and other cholesterol-related disorders.

Symptoms of Xanthelasma

The most common symptom is the appearance of yellowish, raised patches on or around the eyelids. They may appear on one or both eyes, sometimes symmetrically.

Other features include:

• Yellow to orange patches on the eyelid skin

• Flat, nodular, or slightly elevated structure

• May be soft or firm in texture

• Usually painless and not itchy

• Well-defined edges, though in some cases they may appear less distinct

Although they do not typically cause discomfort, xanthelasma lesions that increase in size can affect eyelid movement and should be treated before becoming problematic.

Treatment Options for Xanthelasma

Most xanthelasma cases are benign and do not require urgent medical intervention unless they cause cosmetic or functional concerns. However, if the fatty deposits grow larger or interfere with vision, treatment options include:

Surgical Removal

A small excision with a fine blade to remove fatty tissue is the most common and effective treatment. In more advanced cases, tissue grafting may be necessary.

Chemical Peeling

Application of chemical agents like trichloroacetic acid directly to the lesions can help reduce or eliminate deposits.

Cryotherapy

Controlled freezing of the lesions may remove fatty deposits, though it carries a risk of swelling, scarring, and changes in eyelid tissue.

Laser Ablation

Laser treatment offers a less invasive method but may cause pigmentation changes on the skin.

Electrodessication

Often used in combination with other techniques, this method removes lesions by burning and scraping abnormal tissue growth.

Frequently Asked Questions About Xanthelasma

Is xanthelasma contagious?

No. Xanthelasma is caused by cholesterol buildup under the skin, not by viruses, bacteria, or parasites. It is not contagious.

Is xanthelasma dangerous?

Generally, xanthelasma is not harmful. Small and stable deposits are benign and often do not require treatment. However, larger or growing lesions may need removal for cosmetic or functional reasons. In some cases, they may recur after treatment, especially if caused by genetic factors.

Does xanthelasma affect vision?

While xanthelasma does not cause pain, itching, or burning, large deposits can weigh down the eyelids, limit movement, and narrow the visual field. In such cases, treatment is recommended to restore comfort and normal vision.
