What Is Xanthelasma Palpebrarum?

Xanthelasma palpebrarum, also called xanthelasma palpebrae, is a build-up of cholesterol-rich fat just under the skin of the eyelids. It shows up as soft, flat or slightly raised yellow patches, most often near the inner corner of the eye. It’s common, harmless in itself and not catching, but because it can be linked to raised cholesterol, it’s worth a check with your GP. Nothing you did caused it, and nothing about it can be passed on to anyone else.

Most patches start small, about the size of a grain of rice, on the upper eyelid near the nose. Over months or years they can slowly lengthen along the lid, thicken a little, or appear on the lower eyelid too. Some people only ever have one small patch; others find new ones forming nearby. They rarely grow fast, but they seldom shrink by themselves either.

You’ll also see them called eyelid plaques, xanthelasmata or cholesterol deposits on the eyelids. If you’re wondering why do I have xanthelasma, our guide explains the usual reasons calmly.

What Does Xanthelasma Mean?

The word comes from Greek: xanthos means yellow and elasma means a plate or sheet, so xanthelasma simply means a yellow plate. Palpebrae is Latin for the eyelids, which is why doctors say xanthelasma palpebrarum, “of the eyelids”. One patch is a xanthelasma; several are xanthelasmata. It’s often misspelt xanthlesma, too.

Around one person in a hundred has xanthelasma. It’s most often noticed between the ages of 30 and 60, slightly more often in women, and it can run in families. Many people with it have perfectly normal cholesterol, so having patches doesn’t mean you’ve done anything wrong.

Is Xanthelasma A Type Of Xanthoma?

Yes. Xanthoma is the umbrella name for fatty deposits in the skin, and xanthelasma is by far the most common kind. Other xanthomas appear on the elbows, knees, tendons or buttocks and look different, as you’ll see further down. If you’d like the bigger picture, our guide on what is xanthoma sets out how the two compare and which ones need a doctor.

Eyelid xanthelasma doesn’t usually itch, hurt or affect your eyesight. The trouble is mostly how it looks, and the questions it raises. Patches don’t usually fade with time, and they can become larger or more numerous, which is why people ask will xanthelasma go away on its own. The honest answer is: rarely.

Eyelid Xanthelasma And Cholesterol

Everyone with xanthelasma palpebrae should have their blood fats checked, usually with a simple cholesterol blood test from their GP. About half of people with patches have raised cholesterol or triglycerides, often without knowing it; the other half have normal results. Our guide to eye cholesterol explains what the results can and can’t tell you.

What Doctors Look For

Most doctors recognise xanthelasma palpebral patches at a glance: soft, yellow, flat or gently raised, and on the eyelids near the nose. What they’re more interested in is what might sit behind them. Medical reviews such as StatPearls describe the usual checks.

First comes your cholesterol and triglycerides. Raised levels can run in families, as in familial hypercholesterolaemia, where cholesterol is high from a young age. Your doctor may also check your thyroid, blood sugar, liver and kidneys, because an underactive thyroid, diabetes, some liver conditions and some kidney conditions can all push blood fats up. Very rarely, eyelid patches are part of an inherited condition such as cerebrotendinous xanthomatosis, which affects how the body handles cholesterol and usually shows other signs too. For most people, though, the tests are reassuring.

If a patch were looked at under a microscope, it would show clusters of foam cells in the upper layer of the skin. These are the body’s clean-up cells, called macrophages, that have filled up with tiny droplets of fat until they look bubbly, a bit like foam. They tend to gather around small blood vessels just beneath the surface, and it’s this fat-filled layer that gives the patch its yellow colour.

Image B: a much closer view of the same cells. Each one is packed with fat droplets, which is what makes them look foamy and pale, and why the patch looks yellow from the outside.

Can Xanthelasma Come Back?

It can. Removing a patch, by any method, deals with the fat that’s there now. It can’t change what made it form, so new patches can appear later, especially if cholesterol stays raised.

Tests Your Doctor May Suggest

Usually a quick look at your eyelids is enough, followed by a blood test rather than a skin sample.

That blood test normally covers cholesterol, triglycerides, blood sugar, thyroid and liver function. Because research has linked xanthelasma with heart health, your doctor may also ask about blood pressure, smoking and family history to build a full picture.

Is It Definitely Xanthelasma?

Some eyelid bumps look similar, such as milia or syringoma, which are skin-coloured or white rather than yellow. Our guide to xanthelasma vs syringoma helps you tell them apart.
