Histopathology Artifacts Quiz



This slide was left, unprotected, on a hotplate to dry overnight. The micrograph shows fungal hyphae and conidia across the centre of the section. Mounted, unstained sections which are left uncovered, can become contaminated with a variety of airborne materials. They should therefore be stored wherever possible, in a dust-free environment before staining. So the correct answer here is fungal contamination.
