This is not an easy case. In the above silver stains, there are seemingly intraluminal thrombi. But the EM photos do not demonstrate something which I can correlate with the finding at the light level.
There are many electron dense dust-like particles in the EM photos. My feeling is that they are lead contamination deposits.
