[Pseudoxanthoma elasticum. A X-ray microanalytic study].

We present a very typical case of pseudo-xanthoma elasticum (PXE) with very remarkable cutaneous lesions, a great number of angioid streaks and, at the moment, with no involvement of the peripheral vascular system. From a genetic standpoint, we believe it must be considered as recessive Type I. An X-ray microanalysis was performed showing intense Ca and P deposits in the affected areas as well as complete absence of Si.
