The condition had been asymptomatic for its entire duration (5 years). He reported past intranasal application of 10% Silver Vitellinate. A skin biopsy was performed and histology corroborated the clinical diagnosis of Argyria. This case represents a currently rare dermatological curiosity. Although silver colloids and salts have been withdrawn and\/or banned by some drug surveillance agencies, they continue to be freely sold and unregulated as food supplements and as ingredients in alternative medicines, thereby risking the emergence of new cases of silver poisoning.<\/jats:p>","DOI":"10.1590\/abd1806-4841.20131864","type":"journal-article","created":{"date-parts":[[2013,7,11]],"date-time":"2013-07-11T14:28:58Z","timestamp":1373552938000},"page":"413-416","source":"Crossref","is-referenced-by-count":13,"title":["Argyria - Case report"],"prefix":"10.1590","volume":"88","author":[{"given":"Andre","family":"Lencastre","sequence":"first","affiliation":[{"name":"Central Lisbon Hospital Center,  Portugal"}]},{"given":"Maria","family":"Lobo","sequence":"additional","affiliation":[{"name":"Central Lisbon Hospital Center,  Portugal"}]},{"given":"Alexandre","family":"Joao","sequence":"additional","affiliation":[{"name":"Central Lisbon Hospital Center,  Portugal"}]}],"member":"530","reference":[{"key":"ref1","doi-asserted-by":"crossref","DOI":"10.1155\/2010\/910686","article-title":"A pharmacological and toxicological profile of silver as an antimicrobial agent in medical devices","author":"Lansdown A","year":"2010","journal-title":"Adv Pharmacol Sci"},{"key":"ref2","first-page":"832","article-title":"Rapid onset of Argyria induced by a silver-containing dietary supplement","volume":"38","author":"Bowden L","year":"2011","journal-title":"J Cutan Pathol"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"308","DOI":"10.5021\/ad.2009.21.3.308","article-title":"A Case of Argyria following colloidal silver ingestion","volume":"21","author":"Kwon H","year":"2009","journal-title":"Ann Dermatol"},{"key":"ref4","doi-asserted-by":"crossref","first-page":"730","DOI":"10.1067\/S0190-9622(02)61574-9","article-title":"Scar-localized Argyria secondary to silver sulfadiazine cream","volume":"49","author":"Fisher N","year":"2003","journal-title":"J Am Acad Dermatol"},{"key":"ref5","doi-asserted-by":"crossref","DOI":"10.1136\/bcr.08.2008.0606","article-title":"Argyria: permanent skin discoloration following protracted colloid silver ingestion","author":"Thompson R","year":"2009","journal-title":"BMJ Case Reports"},{"key":"ref6","doi-asserted-by":"crossref","first-page":"556","DOI":"10.1136\/jcp.47.6.556","article-title":"Systemic argyria","volume":"47","author":"Prescott R","year":"1994","journal-title":"J Clin Pathol"},{"key":"ref7","doi-asserted-by":"crossref","first-page":"1408","DOI":"10.1212\/01.WNL.0000120671.73335.EC","article-title":"Myoclonic status epiplepticus following repeated oral ingestion of colloidal silver","volume":"62","author":"Mirsattari S","year":"2004","journal-title":"Neurology"},{"key":"ref8","first-page":"751","article-title":"Successful treatment of Argyria using a lowfluence Q-switched 106-nm Nd:YAG laser","volume":"50","author":"Han TY","year":"2011","journal-title":"Int J Dermatol"},{"key":"ref9","doi-asserted-by":"crossref","first-page":"253","DOI":"10.2165\/00128071-200102040-00006","article-title":"Drug induced skin pigmentation.
