Grossing, often referred to as “cut-up”, involves a careful examination of the specimen to ensure that the proper area is chosen and the specimen is the proper thickness. Larger specimens may require further dissection to produce representative pieces from appropriate areas. For example multiple samples may be taken from the excision margins of a tumor to ensure that the tumor specimen has normal tissue surrounding it to check for infiltration. In the case of small specimens the entire specimen may be processed. The tissues selected for processing will be placed in cassettes (small perforated baskets) and batches will be loaded onto a tissue processor for processing through to wax.
