We receive bone marrow specimens collected by oncologists in their
office.

The bone marrow CLOT is immediately put in Bouin's fixative, fixed
overnight

and processed in a paraffin block.

We are having a very difficult time cutting sections from the clot
specimen.

We have no problem cutting the bone biopsy.

I have been told the difficulty might be caused by the oncologist using
heparanized syringes.

Does anyone have any suggestions that might help us prepare acceptable
slides from the clot?

Thanks.
