"Giant axonal neuropathy" caused by industrial chemicals: neurofilamentous axonal masses in man.

Symmetrical polyneuropathy developed in two patients after they had been in contact with acrylamide and methyl n-butyl ketone, respectively. In sural nerve biopsy material from both patients, electron microscopy showed frequent focal axonal swellings containing masses of neurofilaments. Some axons undergoing axonal degeneration also were seen. These morphologic features are identical to those produced in experimental animals after exposure to these chemicals and are similar to those found in n-hexane neuropathy and in the three reported cases of giant axonal neuropathy. Sural nerve biopsy is an important diagnostic test in identifying cases of peripheral neuropathy caused by these chemicals.
