== | =====Micro===== | ||
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. | |||
