style='font-size:10.0pt;font-family:"Comic Sans MS";color:blue'>One of our
pathologists and myself have been trying to identify some
black intracellular pigmentation in a bronch lavage. We have ruled
out carbon, and bleaching the section did not work, therefore is not
melanin. It is a very fine dark black pigment and appears quite uniform
in shape and size. Our pathologist is thinking that it is lead (the
patient is a long time professional painter), but lead stains are
negative. My other thought is aluminum deposits but have not yet stained
for this.</span></font></p>
