Persistent Mercury in Nerve Cells 16 Years After Metallic Mercury Poisoning

Neuropathol Appl Neurobiol. Nov-Dec 1988;14(6):443-52. doi: 10.1111/j.1365-2990.1988.tb01336.x.

Abstract

A male subject, after exposure to mercury metal at work in 1968, developed classical signs of mercurialism from which he made a slow clinical recovery. He subsequently developed psychoneurotic symptoms and became an alcoholic; he never returned to work and died in 1984. No histological changes relevant to mercury intoxication were found in the brain, but staining by Danscher & Schroeder's method for mercury showed many positively staining lysosomal dense bodies in a large proportion of nerve cells, and the presence of mercury was confirmed by elemental X-ray analysis. The mercury content of the brain was increased, much of it being present in colloidal form.
