The sections show the transformation zone. The squamous epithelium has cells with an increased nuclear size, nuclear hyperchromasia, perinuclear clearing and irregularities in the nuclear membrane. The nucleus-to-cytoplasm ratio is mildly increased. Occasional binucleation is identified. Mitoses are seen in the low third of the epithelium. Nucleoli are not apparent. No columnar dysplasia is identified. | The sections show the transformation zone.
