[Pseudoxanthoma elasticum. Morphological and biomechanical study of dominant type 1 and recessive type 2 forms].

A study of two genetically distinct types of pseudoxanthoma elasticum was performed by optical microscopy, scanning electron microscopy and by tonometry. No difference was recognized and measured between the two groups of patients because interindividual variability of the dermal alteration is so large in each of the groups.
