Spinal changes in the neuropathy of thallium poisoning. A case with neuropathological studies.

Thallium poisoning in a man of 32 years resulted in typical peripheral neuropathy, skin rash and alopecia. Post-mortem studies showed widespread loss of peripheral nerve fibres and chromatolysis in spinal neurones. The distal nature of the nerve fibre degeneration in thallium poisoning and the sensitivity of long fibres is emphasized in this case.
