A skin biopsy a 37 year old man with typical lesion of pseudoxanthoma elasticum associated with angioid striae (Groenblad-Strandberg syndrome) was examined with a scanning EM (SSM-2A) and a scanning EM provided with a X ray microanalyser. With the scanning EM (SSM-SA) it was possible to see tabular crystalline deposits with subround faces and rhombohedric tendency. The scanning EM provided with a X ray microanaliser enabled us to see crystalline deposits which in some fields adopt a star-shaped form corresponding to calcium crystals of not very well defined habit. The X ray microanalyser shows us the correspondence between the star shaped figures and a calcium salt. The potassium, sodium and magnesium analysis of the specimen permits us to verify that the pseudoxanthoma elasticum dermis is rich in K and poor in Mg.
对一名患有与血管样条纹相关的弹性假黄瘤典型病变（格伦布拉德 - 斯特兰德伯格综合征）的37岁男性进行了皮肤活检，使用扫描电子显微镜（SSM - 2A）以及配备X射线微分析仪的扫描电子显微镜进行检查。使用扫描电子显微镜（SSM - SA）可以看到具有亚圆形面和菱形倾向的板状晶体沉积物。配备X射线微分析仪的扫描电子显微镜使我们能够看到晶体沉积物，在某些区域呈现出对应于习性不太明确的钙晶体的星形形态。X射线微分析仪向我们展示了星形图形与钙盐之间的对应关系。对标本进行的钾、钠和镁分析使我们能够证实弹性假黄瘤真皮富含钾而镁含量低。
