Surely all are examples of carryover.
Carryover is anything that "didn't ought to be there" and has come from another specimen.
It must be difficult to monitor, and the most difficult (i.e. impossible) is the like-to-like tissue carryover, that is to say, a bit of A's endometrium appearing on B's slide.
Cut-up and water bath are the most likely origins, and can be minimised by scrupulous cleanliness.

Could you define carryover? Do you mean cells, tissue fragments, stains
from one staining dish to another?
