[Histonet] tissue array

[Henry, Charlene]

We have made multiple tissue array blocks for research projects and many
of the tissue blocks are from cases 28 years ago. Over the years the
paraffin has changed from the old harder paraffins to the softer
paraffins we use today. I prefer to re-embed my older paraffin blocks
and then obtain a new H&E slide for the pathologist to select desired
area to be punched. After the blocks have been re-embedded, they work as
well as the current blocks.
