Electron microscopy of ultra-thin sections of lepromatous peripheral nerves.

The submicroscopic structure of peripheral nerves are now being revealed by many investigators (1 , 2, 3, 8) using the high resolving power of the electron microscope. Stimulated by this recent progress in neurology, we have made an electron microscope study of ultra-thin sections of leprous peripheral nerves. In the present article we report on such a study of sections of great auricular nerves taken from two cases of lepromatous leprosy. In this investigation we were able to elucidate some aspects of the leprous nerve lesions which cannot be observed by the light microscope.
