[Groenblad-Strandberg syndrome. Study with scanning microscopy provided with an X rays analyzer].

Abstract

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.
