Currently, they are worked by interdisciplinary groups seeking answer specific objectives and are associated with well-defined conducts. The cervical cytology had its first systematization with the classes of Papanicolaou, which due to the difficulty of correlating with Histopathology, was gradually abandoned. Other ways to write the reports followed it, as the World Health Organization (WHO) classification – categorized the lesions in dysplasias -, the Richart’s – intraepithelial neoplasia – and finally the Bethesda (nomenclature) System, obtained in a consensus meeting and added important topics, such as the assessment of sample satisfactoriness, atypia of undetermined significance, and the binary division of squamous lesions in low and high grade(2,5).
