Applying heated forceps, orientate the tissue inside the mildew to acquire the desired situation in relation With all the cutting axis; the specimen floor in contact with the base of your mould remaining the 1 that may be over the slide right after sectioning.
If margins are involved by tumor at the initial excision or for shut margins for melanomas, the original region from the lesion could be re-excised.
