==Prolapse==
=====Micro=====
*Pieces of vagina are often submitted in the context of uterine prolapse.
The sections show squamous epithelium with compact keratin, parakeratosis and
hypergranulosis. The nuclei mature normally to the surface.  No significant nuclear atypia is identified. Mitotic activity is not readily apparent. Minimal intracellular edema is present.  No significant inflammation is identified.  A very small amount of fibrous subepithelial tissue is present.
===Microscopic===
*Squamous epithelium - may be keratinized.
