[Problems in Papanicolaou classification]

There are several reasons why Papanicolaou classification should not be used for the interpretation of cytologic findings. First, many different classification criteria are sometimes used for a single pathologic condition. Second, inflammatory change or hormonal evaluation are not included in the system. Third, the classification is not compatible for the evaluation of endometrial lesions or chorionic diseases. Fourth, mismanagement of the patient is sometimes encountered when this classification is only used. Instead of Papanicolaou classification, descriptive diagnosis should be used for cytologic interpretation.
