Gastric xanthomas are tumors in which macrophages phagocytose large amounts of cholesterol and appear in clusters in the gastric mucosa. Most are associated with hereditary or acquired hypercholesterolemia. They can be removed using surgery or physical therapy. Gastric xanthomas are generally foamy and appear in clusters in the gastric mucosa as macrophages phagocytose large amounts of cholesterol, forming a tumor-like mass. Most are associated with hereditary or acquired hypercholesterolemia and can present as a swelling and bulge in the stomach. The main treatments for gastric xanthoma include medication, surgery, and physical therapy. Drug treatment can use lipid-lowering drugs such as niacin, propylbutynol, and kolestyramine for patients with hypercholesterolemia. Surgical treatment is based on surgical removal of the mass. Physical therapy has electrocoagulation, liquid nitrogen freezing, carbon dioxide laser cauterization and other methods to eliminate yellow tumors, but only for smaller yellow tumors. The appearance of gastric yellow tumor should be actively treated under the guidance of doctors to avoid aggravation or development of gastric cancer.
