Acrosclerosis Associated with Vibration: an Electron Microscopic Study.

A case of typical vibration-induced acrosclerosis was studied with the electron microscope. In addition to increased collagenization of the dermis, vascular wall and perivascular spaces, a severe vacuolization and an increased number of lysosomes in the vascular endothelial cells were observed. In many peripheral nerves, axonal degeneration, demyelination and an extensive collagenization of peri- and endoneurium were observed. These changes appeared to be the organic basis for sclerosis and neuropathies of this condition. [ABSTRACT FROM AUTHOR]
