A Case of Argyria / 대한피부과학회지

ABSTRACT

Argyria is a rare skin discoloration caused by the deposition of silver granules in the skin. We report a case of argyria occurring in a 46-year-old woman due to ingestion of colloidal silver solution over 2 years. She had a diffuse, slate gray discoloration on her face and hands. The biopsy specimen from the face revealed melanin hyperpigmentation in the epidermal basal layer. Numerous, round, tiny brown-black granules were deposited in the basement membrane surrounding eccrine glands. Silver solution is being advertised as a cure for a variety of diseases and is commercially available as a 'food supplement'. This case report highlights the potential risk of adverse effects following the use of food supplements.
