What landmarks should be identified during dissection?
Anatomic landmarks (e.g., an axillary tail on a mastectomy) or surgically designated orientation marks (e.g., sutures) must be identified. These landmarks should not be obscured or removed during dissection if they are necessary for orientation. If a landmark must be removed, its location should be identified by colored inks, sutures added by the pathologist, or nicks in the attached skin.
