Abstract
|
|
|
|
Localized cutaneous argyria is a rare condition in which the skin changes into blue-grey spots due to the absorption of silver. The lesions need to be differentiated from other pigmentary disorders and require radiographic and histological examination for more accurate diagnosis. Scanning electron microscopy and energy dispersive x-ray spectroscopy can be a confirmatory tool in the evaluation of silver elements in biopsy tissue. This report shows the localized cutaneous argyria in earlobe of a 21-year-old woman who wears silver earrings for 10 years.
