| Abstrakt: | Abstract: Localized cutaneous argyria is a rare condition caused by the accumulation of silver particles in the skin, leading to blue-gray discoloration. Argyria may mimic melanoma and lead to misdiagnosis. We present a patient with a history of melanoma that developed a blue-gray nodule at a prior melanoma graft. The diagnosis was confirmed using scanning electron microscopy and energy dispersive x-ray analysis. These techniques differentiate argyria from melanoma and can be performed on formalin-fixed, paraffin-embedded, tissue sections. Health care providers should be alert that argyria may mimic recurrent melanoma in patients unaware of silver exposure. Competing Interests: The authors declare no conflicts of interest.
