Artefacts in histopathology

Histopathology is the science of slide analysis for the diagnostic and research purposes. However, sometimes the presence of certain artefacts in a microscopic section can result in misinterpretations leading to diagnostic pitfalls that can result in increased patient morbidity. This article reviews the common artefacts encountered during slide examination alongside the remedial measures which can be undertaken to differentiate between an artefact and tissue constituent.
