A Short, Clear Introduction To The Yellow Spot Found In The Stomach Lining: What It Is, What It’s Linked With, And What Happens Next
Gastric xanthelasma, also called gastric xanthoma, is a small yellow-white patch of fat-filled cells in the stomach lining, usually found by chance during an endoscopy. It isn’t cancer and causes no symptoms, but it’s linked with stomach changes such as H. pylori infection, atrophic gastritis and intestinal metaplasia, so doctors use it as a reason to look more closely.
Gastric xanthelasma is a small, flat or slightly raised yellow-white spot of fat-filled immune cells in the stomach lining, usually 1 to 10 mm across. It’s found in roughly 2% to 7% of endoscopies and causes no symptoms. It isn’t cancer, but it’s linked with H. pylori, atrophic gastritis, intestinal metaplasia and, in some studies, early gastric cancer, so follow-up matters.

What Is Gastric Xanthelasma?
Gastric xanthelasma is a small, yellow-white, flat or slightly raised patch in the stomach lining made of fat-filled immune cells. It’s benign, causes no symptoms, and is usually found by chance during an upper endoscopy.
A large study of 69,071 endoscopies described these lesions as yellow-white, flat or slightly raised and 1 to 10 mm in size.[1] Under the microscope they’re made of foamy histiocytes, immune cells packed with fat, sitting in the lamina propria, the layer just beneath the stomach’s surface lining.[5] The names gastric xanthelasma and gastric xanthoma are used for the same thing; the condition was first named in 1929.[4]
This page is a short introduction. For the full medical guide, see xanthoma gastric. For the wider family of fatty deposits, see our xanthomas guide.
How Common Is Gastric Xanthelasma?
Fairly uncommon but not rare: studies have found it in about 1.8% to 7% of people having an upper endoscopy, depending on who was examined. It’s seen in both men and women, and more often with age.
The 69,071-endoscopy study found it in 1.77% of people, with no difference between the sexes and an average age of 53 compared with 46 in people without it.[1] A study of 771 endoscopies found 7%,[4] and a study of 1,823 health checkup patients found 5.9%, more often in people aged 65 or over, men and people with diabetes.[2] The differences reflect who was being examined and why.
Who Is More Likely To Have Gastric Xanthelasma?
Older adults, people with long-standing H. pylori infection or atrophic gastritis, and, in one study, men and people with diabetes. The chance of having it rises steadily with age.
- Age. Each extra year of age raised the odds by about 4% in the 69,071-endoscopy study, and the average age was 53 versus 46.[1]
- Age 65 or over. Linked with gastric xanthelasma in the 1,823-patient checkup study.[2]
- Men. More common in men in that checkup study,[2] though the larger study found no difference between the sexes.[1]
- Diabetes. Linked with gastric xanthelasma in the checkup study.[2]
- Open-type atrophy. More extensive thinning of the stomach lining was also linked.[2]
None of these means you’ll develop it, and many people with these risk factors never do. They simply describe who it tends to be found in. For the condition in full, see xanthoma gastric.
What Does Gastric Xanthelasma Look Like?
A well-defined yellow-white spot or plaque, usually single, usually under 10 mm, most often in the lower part of the stomach (the antrum). Some people have several.
- Color. Yellow-white, standing out against the pink stomach lining.[1]
- Shape. Flat or slightly raised, with clear edges.[1]
- Size. Average about 7 mm; none over 10 mm in one study.[4]
- Number. Single in about 65% of people; multiple in the rest.[4]
- Location. Antrum in 53.7%, body in 35.2% and fundus in 11.1%.[4]
Only an endoscopy can see it; it can’t be felt or noticed from outside.
What Is Gastric Xanthelasma Made Of?
Foamy histiocytes: immune cells that have swallowed fat, sitting in the lining’s lamina propria. Special stains show they’re immune cells (CD68 positive) rather than gland or surface cells.
A pathology report described the cells as CD68 positive and negative for mucin and cytokeratin, and noted that gastric xanthelasma can mimic signet ring cell carcinoma, a type of stomach cancer, under the microscope, which is why staining matters. Material from H. pylori bacteria has also been found inside the foam cells.[5] The same kind of fat-filled immune cell, the foam cell, makes up xanthomas elsewhere in the body; see what is xanthoma.
Why Does Gastric Xanthelasma Form?
It seems to form as a response to damage or ageing of the stomach lining, often from long-term H. pylori infection and the inflammation it causes. Immune cells clear fats from damaged cells and become foam cells.
Researchers following patients after early gastric cancer removal describe foam cells forming in response to mucosal damage or ageing, and note that gastric xanthelasma persists even after H. pylori has been cleared.[3] That fits the finding of H. pylori material inside the foam cells.[5] In other words, gastric xanthelasma is a footprint of past or present lining damage, which is why it’s useful to doctors. Our guide on xanthomatosis covers fatty deposits more broadly.
Does Gastric Xanthelasma Cause Symptoms?
No. Gastric xanthelasma itself causes no pain, indigestion or other symptoms. Any symptoms you have come from whatever led to the endoscopy, or from linked conditions such as gastritis.
People usually learn they have it from an endoscopy report after being investigated for reflux, indigestion, anemia, screening or another reason. If you have warning symptoms such as weight loss you can’t explain, trouble swallowing, vomiting, black stools or persistent upper abdominal pain, tell your doctor promptly, whatever the report says.
What Is Gastric Xanthelasma Linked With?
H. pylori infection, atrophic gastritis (thinning of the stomach lining) and intestinal metaplasia (lining changes that look like intestine). These are the conditions doctors look for when gastric xanthelasma is found.
In the 69,071-endoscopy study, after adjusting for other factors, gastric xanthelasma was linked with 1.83 times the odds of atrophic gastritis, 2.42 times the odds of intestinal metaplasia and 1.32 times the odds of H. pylori. Intestinal metaplasia was found in 51.9% of people with gastric xanthelasma versus 19.3% without, atrophic gastritis in 42.9% versus 14.3%, and H. pylori in 34.6% versus 27.0%.[1] The authors call it a warning sign for these conditions.
Is Gastric Xanthelasma Linked With Stomach Cancer?
It isn’t cancer and doesn’t turn into cancer, but some studies have found early gastric cancer more often in people who have it, probably because both grow from the same damaged lining. The link is a reason for follow-up, not a diagnosis.
In the 1,823-patient checkup study, early gastric cancer was found in 14.0% of people with gastric xanthelasma versus 0.8% without, with odds 5.85 times higher after adjustment.[2] In 115 patients followed for a median of 55 months after early cancer removal, new cancers developed in 27.1% of those with gastric xanthelasma versus 8.9% without.[3] The large 69,071 study found cancer in 1.5% versus 0.9%, but the difference wasn’t independent of the other lining changes.[1]
So the lesion itself isn’t the danger: it flags a stomach lining that’s worth watching. Your doctor will decide whether you need follow-up endoscopy.
What Studies Have Found About Gastric Xanthelasma
| Study | People | How Common | Key Finding |
|---|---|---|---|
| Feng 2023 | 69,071 endoscopies | 1.77% | Linked with atrophic gastritis, intestinal metaplasia and H. pylori |
| Sekikawa 2016 | 1,823 checkup patients | 5.9% | Early gastric cancer 14.0% vs 0.8% |
| Fukushima 2022 | 115 after early cancer removal | n/a | New cancer 27.1% vs 8.9% over a median 55 months |
| Yi 2007 | 771 endoscopies | 7% | Higher LDL, lower HDL; atrophic gastritis 44.4% vs 14.8% |
| Andrejic 2012 | 2 case reports | n/a | Can mimic signet ring cell carcinoma; H. pylori material in foam cells |
Is Gastric Xanthelasma Linked With Cholesterol?
Possibly. One study found people with gastric xanthelasma had higher LDL and lower HDL cholesterol than people without it, though the link with stomach lining changes is much stronger.
In the 771-endoscopy study, average LDL was 112.9 mg/dL in people with gastric xanthelasma versus 95.9 without, and HDL was 48.8 versus 62.9; atrophic gastritis was present in 44.4% versus 14.8%.[4] That’s one study, so it isn’t a reason to assume your cholesterol is high, but if you haven’t had a lipid check recently, it’s reasonable to ask. Our guide to the causes of xanthelasma covers the cholesterol link for the eyelid form.
How Is Gastric Xanthelasma Diagnosed?
During an upper endoscopy, the doctor sees the yellow-white spot and may take a small biopsy. The pathologist confirms the foam cells and checks the surrounding lining for gastritis, metaplasia and H. pylori.
- Endoscopy. A thin camera passed through the mouth into the stomach.
- Recording. The size, number and position of any lesions.
- Biopsy. Small samples of the spot and, often, the surrounding lining.
- Staining. Confirms the cells are fat-filled immune cells, not cancer cells.[5]
- H. pylori testing. On the biopsy or by breath or stool test.
What Happens After Gastric Xanthelasma Is Found?
The spot itself is usually left alone. Care focuses on the stomach lining: clearing H. pylori with antibiotics if it’s present, managing gastritis, and follow-up endoscopy if the lining shows atrophy or metaplasia.
Because gastric xanthelasma tends to persist even after H. pylori has been cleared,[3] seeing it again on a later endoscopy doesn’t by itself mean something has gone wrong. What matters is the state of the surrounding lining. Your gastroenterologist will set the plan based on your biopsy results, age and family history.
- Follow the surveillance plan you’re given.
- Complete any course of antibiotics for H. pylori, and have the follow-up test to confirm it’s gone.
- Don’t smoke, and keep alcohol moderate.
- Report new or warning symptoms promptly.
Is Gastric Xanthelasma Related To Eyelid Xanthelasma?
They share a name and the same kind of fat-filled cell, but they’re different conditions in different places with different causes. Having one doesn’t mean you have, or will get, the other.
Eyelid xanthelasma is a skin condition linked with blood fats and heart health; gastric xanthelasma is a stomach lining finding linked mainly with H. pylori and lining damage. If you also have yellow patches on your eyelids, our main xanthelasma guide and eyelid xanthomas explain that condition. For the meaning of the word, see what we mean by xanthelasma, and for the name itself, how to pronounce xanthelasma.
Fat-filled foam cells can collect in other parts of the body too, each with its own causes and its own name: flat patches in the skin, firm lumps on tendons, or crops of small bumps. Our guides to xanthoma, skin xanthomas, plane xanthoma and tendon xanthomas explain those forms. None of them is caused by gastric xanthelasma, and finding one doesn’t mean you have the others.
What Should You Ask Your Doctor About Gastric Xanthelasma?
Ask what the biopsies showed around the spot, whether you have H. pylori, whether there’s atrophic gastritis or intestinal metaplasia, and whether and when you need another endoscopy.
- “Was a biopsy taken, and what did it show?”
- “Do I have H. pylori, and how will we clear it?”
- “Is there atrophic gastritis or intestinal metaplasia?”
- “Do I need follow-up endoscopy, and when?”
- “Does my family history change anything?”
- “Which symptoms should make me call sooner?”
Our full guide to xanthoma gastric goes into each of these in more depth.
What’s The Bottom Line On Gastric Xanthelasma?
Gastric xanthelasma is a small, benign yellow-white patch of fat-filled cells in the stomach lining, found by chance on endoscopy. It causes no symptoms itself, but it’s linked with H. pylori, atrophic gastritis, intestinal metaplasia and, in some studies, early gastric cancer, so follow your doctor’s plan.
