Background/Aim:
The clinical significance of gastric xanthelasmas is unknown. We conducted a case-control study in order to evaluate whether gastric xanthelasma is an indicator of advanced atrophic gastritis and intestinal metaplasia.
Material And Method:
The study was conducted among 1400 patients who underwent elective upper endoscopy. Patients with gastric xanthelasma and atrophy and/or intestinal metaplasia constituted the study group (n = 55). The control group involved patients with only atrophic gastritis and/or intestinal metaplasia (n = 50). Histopathologic findings of the groups including the distribution of atrophic gastritis and/or intestinal metaplasia, operative link on gastritis assessment score, operative link on gastritis intestinal metaplasia assessment (OLGIM) score, and presence of dysplasia and malignancy were compared. Subgroup analysis was performed in order to establish the relation between the characteristics (size, number, and localization) of xanthelasmas, atrophy, and intestinal metaplasia.
Results:
Multifocal atrophic gastritis was significantly more common in patients with a gastric xanthelasma (41.8 vs. 26.0 %, p = 0.03). Patients with multiple xanthelasmas had a significantly higher rate of intestinal metaplasia (p = 0.02) and a higher OLGIM score (p = 0.02) compared to those with a single xanthelasma. Dysplasia was detected in 8 (14.5 %) patients with a xanthelasma and 4 (8.0 %) patients without a xanthelasma (p = 0.2).
Conclusion:
Gastric xanthelasma(s) is a warning endoscopic sign for the presence of multifocal atrophic gastritis and advanced intestinal metaplasia.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
01:17Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
