As a pathologist who sees tattoo ink in lymph nodes routinely (along with other pigments), it's slightly shocking to me that this got reported as a finding.
There is, however, an interesting suggestion of correlation between certain red pigments, particularly from tattoos made in Asia it seems, that stimulate the immune system to mount a severe epidermolytic reaction. And it can be a delayed reaction. We had one where the dermatologists brought in pictures. It looked like the entire tattoo was being cut out with a cookie cutter, just totally separated from the surrounding skin. Horrible.

It is the response of the body to clean the site,” study coauthor Bernhard Hesse, a visiting scientist at the European Synchrotron Radiation Facility (ESRF) in Grenoble, France, says in a press release. “What we didn’t know is that they do it in a nano form, which implies that they may not have the same behaviour as the particles at a micro level. And that is the problem: we don’t know how nanoparticles react.”
