Histological change of biopsy specimens. a Two-year exposure to lanthanum: Only a few histiocytes containing crystalline eosinophilic deposits were observed (white arrow). b Three-year exposure to lanthanum: Granular or crystalline eosinophilic deposits and infiltration of histiocytes corresponding to the inflammation increased in lamina propria (yellow arrow). c, d Four-year exposure to lanthanum: The crypt density reduced, and chronic gastritis, regenerative changes, and intestinal metaplasia were more apparent. The deposits and histiocytes that phagocytose them more increased. Panel (d) shows the high-magnification image of the area of (white square in (c))
