Localized cutaneous argyria: a report of 2 cases

Clinical and Forensic Aspects of the Different Subtypes of Argyria

Argyria encompasses the different cosmetic alterations that can develop if enough silver particles deposit in a specific tissue, typically in the skin, ranging from localized dark-blue macules to a generalized slate-gray/bluish tinge following systemic absorption. This work aims to fully review the state of the art regarding pathophysiology, diagnosis, treatment, and relevant clinical and forensic features of argyria. Argyria has been diagnosed in a wide range of ages, both sexes and varied ethnicities, with no known individual predisposing factors. Ultraviolet radiation with subsequence increases of melanin production aggravates the discoloration due to a reduction in the silver deposits. Physical examination and silver exposure in the anamnesis can be highly suggestive of the diagnosis, but a histopathological analysis with Energy-Dispersive X-ray Spectroscopy is required to unequivocally determine the discoloration etiology. Safe and effective treatment has only been accomplished with laser techniques, though only a few cases have been reported and with limited follow-up time. In conclusion, argyria typically has an occupational or iatrogenic etiology. It should be suspected when a patient presents with typical skin or eye lesions. A seemingly viable treatment modality, with laser technology, is finally within the horizon.

Localized Cutaneous Argyria Mimicking Blue Nevus after Wearing Earrings

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.
