Summary
A 72-year-old woman developed generalized argyria after prolonged intranasal application of a colloidal silver solution. The brain parenchyma, including several infarcts, was free of silver, but the choroid plexus showed silver deposited in the basal lamina, the stroma including calcified bodies, and occasionally within a mesenchymal cell of the choroid plexus stroma. The basal lamina beneath the choroidal epithelium was most affected. The silver granules appeared solid and free of any limiting membrane.
