Just curious; why do you keep placenta blocks longer than any other tissue
blocks?

We keep our blocks for twenty years and all of our placenta blocks for 25
years (we file them separately).  The blocks are disposed of as regular
trash.  We keep our wet tissue for 6 weeks after the accession date - just
to be sure the case is signed out.  We also keep our empty spec containers
for 2 weeks (in case of a labeling problem).  All our slides are kept for 20
years.  It certainly amounts to a large area for storage...........By the
way, we use "Pizza Hut" boxes to store our blocks in - we get them free from
the local Pizza Hut and the blocks fit perfectly.  The boxes are fairly
heavy duty cardboard and the price is certainly right!!
