A Series of Tattoo-associated Infections.

Mycobacterium fortuitum is a rapidly growing mycobacterium known to spread through many sources, including tap water. This organism can have variable presentation between patients which can lead to a delay in diagnosis. Here, we report a series of eight cases of tattoo-associated M. fortuitum infections that presented between December 2010 and January 2011, which were later linked to a single tattoo provider using gray tattoo ink made by diluting black ink with nonsterile tap water. In this case series, we emphasize the lack of pathognomonic features of these infections, the variability in culture and biopsy results, the importance of obtaining a culture in addition to a biopsy, and the importance of identifying the source of infection when determining management.
