A Case Study of Argyria of the Nails Secondary to Colloidal Silver Ingestion

This case report documents the rare finding of argyria limited to the nails secondary to colloidal silver ingestion. We highlight the significance of early detection of argyria secondary to colloidal silver ingestion and offer photos of the subtle changes in the nails that indicate the development of argyria. With the popularity of over-the-counter supplementation, it is important for medical providers to be aware of early signs of argyria, prior to progressive, permanent pigmentary changes.
