We had for aim to describe and illustrate the artefacts observed in biopsies of the oral mucosa, as well as the impact of sending non-representative histological material to a laboratory. This article was based on an international literature review, as well as on our experience. We analysed the problems raised, for the pathologists and the histology lab-technicians, by these artefacts as well as their impact on the pathology report patient management. We suggest simple solutions.
