Histopathology Artifacts Quiz



This micrograph shows three circular, darkly stained areas with pale centres and surrounding radial cracks. After flotation and mounting on a slide these areas contained air bubbles which collapsed during drying leaving zones which are cracked and have not adhered properly to the slide. The poor adherence produces altered staining. The answer therefore is collapsed bubbles under the section.
