Gastric xanthoma.

Gastric xanthoma (GX) consists of a small yellowish lesion of the gastric mucosa, frequently of multiple occurrence; histologically, there is an accumulation of lipid-laden histiocytes in the lamina propria. Seven cases are reported. One patient also had jejunal localizations. There is no correlation with hypercholesterolemia but in four cases a slight hypertriglyceridemia was found. A control gastroscopy, performed in four cases, revealed no changes in the first patient but a decrease in size in a second and the disappearance of GX in two other patients.
