Abstract

Gastric xanthoma which is not a true neoplasm and clinically insignificant consists of the small yellowish lesion of the gastric mucosa, frequently of multiple occurrence. Histologically the lesion shows chronic superficial gastritis with intestinal metaplasia and occasional collections of foam cells within the lamina propria. Electron microscopically. the xanthoma, cells are composed of. lipid-laden histiocytes with. many autophagocytic Iysosomes surrounding the cytoplasmic lipid vacuoles. Many residual bodies are also noted. The pathogenesis of the gastric xanthoma is obscure, however it is thought that a previous focal lesion of the gastric mucosa may have been a factor. One case of gastric xanthoma is reported here and a brief review of literature is also made.
