24 cases of amalgam pigmentation were analyzed by light microscope. 16 cases were amalgam debris, 8 cases were amalgam fragments and debris mixed. The amalgam distributed mainly along basement membrane of the epithelium, wall of blood vessels, nerve fibers, reticular fibers and endomysiums. In case where amalgam entered the bone, bone cells disappeared, lacuna emptied and microfracture of bony trabecullae occurred. In 8 cases pathologic calcification were found and in 18 cases there were inflammatory responses. 2 cases were analyzed by energy dispersive X-ray. It was found that in the different sites of tissues there were different content of Ag, Hg, Sn and Ca.
对24例汞合金色素沉着病例进行了光镜分析。其中16例为汞合金碎屑，8例为汞合金碎片与碎屑混合。汞合金主要沿上皮基底膜、血管壁、神经纤维、网状纤维和肌内膜分布。当汞合金进入骨组织时，骨细胞消失，骨陷窝空虚，骨小梁出现微骨折。8例发现病理钙化，18例有炎症反应。对2例进行了能量色散X射线分析，发现在组织的不同部位，银、汞、锡和钙的含量不同。
