Argyria and cyanotic heart disease.

A case report in which argyria is mistaken for cyanotic heart disease is described. A discussion of argyria, a benign cosmetic condition resulting from either ingestion or the local application of silver salts or colloidal silver, is presented. It is suggested that by obtaining comprehensive drug histories, maintaining patient profiles, and through patient counseling, pharmacists are in a position to identify and advise on known cases of argyria.
