Gastric xanthoma, also known as gastric macular tumor or gastric lipid island, is a benign lesion that occurs in the gastric mucosa as a result of fatty deposits. Its etiology and pathogenesis are not yet clear, and may be related to gastric mucosal damage and repair, intestinal metaplasia, and abnormal lipid metabolism. Gastric xanthoma can be seen in any part of the stomach, usually in gastric antrum and pylorus region. Gastric xanthoma is reported to be associated with increased risk of early gastric cancer. This article reviewed the progress of research on correlation between gastric xanthoma and gastric cancer and precancerous lesions.
