[Histonet] Liver Core Biopsies

[Merry Lewis]

Hello there!

We are having some issues with our liver biopsies and can't seem to find any solutions.  The biopsies are sent to us from IR already in formalin, we bake them in a 65* C oven for 30 minutes (to ensure fixation) and then we microwave process them.  The microwave process is reagent alcohol, 5 mins, isopropanol, 5 mins, and finally paraffin, 2 min at 65* C and 5 min at 70* C.  Worth noting: this is our procedure for all our biopsies - liver, heart, kidney, GI - and liver is the only one we are having problems with.  The livers section well and don't appear to be over processed; however, without exception, they have a drying artifact on the outer edges.  I have spoken to IR and they confirmed that they do not leave the biopsies out to dry for any amount of time.  If they can't put them directly into formalin, the liver cores are held on saline soaked pads for no longer than a minute.  I have seen suggestions about local anesthesia causing problems, but as we have no control over that and it's a necessary evil, I'd like to see if anyone has a suggestion to help minimize the artifact.

Thanks!
