The foam cell of xanthelasma of the stomach is lipid laden histiocyte having a number of microvilli measuring approximately 0.1 μ in width and 2–3μ in length. In the cytoplasm, a number of lipid particles of vacuolar type and osmophilic type were seen but the former type was more numerous. Lipid particles were also observed in the plasma cells, pericytes and smooth muscle cells of the lesion and all these particles were of vacuolar type. It was estimated that the lipid accumulation in the cytoplasm in case of xanthelasma of the stomach is not entirely caused by phagocytosis but by localized change in metabolic pathway of lipid. It is most likely that lipid consists of various constituents including from neutral fat to fatty acids. ACTA PATH. JAP. 20: 357–363, 1970.
