===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. | |||
