====Koilocytes versus benign squamous====
Koilocytes:
*Perinuclear clearing.
*Nuclear changes.
**Size similar (or larger) to those in the basal layer of the epithelium.
**Nuclear enlargement should be evident on low power, i.e. 25x. <ref>V. Dube 2008.</ref>
**Central location - nucleus should be smack in the middle of the cell.
Notes:
# Both perinuclear clearing and nuclear changes are essential.
# Benign cells have a small nucleus that is peripheral.
