Dear all,

One of my pathologists has a very difficult case.  He is almost
certain he has the pigment cinanbar(mercury based), which is used as
the red in tatoos, in macrophages.
We are wondering what is the simplest way to identify this pigment if
it is mercury.  We have only on Cytology smear containing this
material and do not want to destroy the slide!!!!

Thank you.
