[Anatomical study of Peyronie's disease].

An electron microscope study in the course of post-mortem examinations demonstrates the normal structure of the penis as a function of age. Twenty patients presenting with Peyronie's disease were examined in accordance with the same protocol. The lesions consisted of changes in the collagen fibers with inflammation, later followed by fibrosis, giving an idea of the stage of evolution of the disease. None of the etiopathological theories put forward to date provides a really satisfactory explanation of this mysterious disease.
