Gastric yellow tumor, also known as reticuloendothelial cell tumor or lipid island, refers to a tumor-like proliferative lesion in which lipid-like macrophages are focally aggregated, which is a pseudotumor and a proliferative response of tissue cells to plasma lipid changes:
When the tissue is focally damaged or repaired, many residual lipid-containing cell fragments are taken up by phagocytes and eventually form foam cells. The foam cells are the important histopathological basis of yellow tumor, so it is believed that mucosal damage is its main causative factor. 2, Gastric mucosa damage affects lipid transport, causing lipids to accumulate in the cells and forming lipid crystals. It indicates that there is a local disorder of lipid metabolism in the lesion. 3, gastric mucosa intestinal epithelial metaplasia, the literature reports that the incidence of this disease in patients with intestinal metaplasia is three times that of those without intestinal metaplasia, indicating that the occurrence of this disease is related to gastric mucosa intestinal metaplasia. Gastric yellow tumors can occur anywhere in the stomach, most commonly in the lesser curvature of the gastric sinus, followed by the antrum. The lesions may be solitary or multiple, with multiple lesions being common. Gastric yellow tumors often have no specific symptoms or signs, but are only detected during gastroscopy and diagnosed by gastroscopy, pathology and PAS histochemical staining.
It is yellow or yellow-white in color, with clear border and slightly rough surface. Gastric yellow tumors have been considered as precancerous lesions and early coagulation is advocated. Argon ion coagulation (APC) treatment of gastric yellow tumor can make it turn white, coagulate, vaporize, necrotize and fall off, which is helpful to improve or restore the normal physiological function of gastric mucosal epithelium and has positive significance to prevent the occurrence of early gastric cancer and relieve the patients’ fear of cancer. Gastroscopic argon knife treatment of gastric yellow tumor is effective, simple, convenient and safe, and is worthy of clinical promotion.
