1) The present status of gynecological exfoliative cytology is briefly reviewed and ten cases of cervical lesion on which cytologic examination was performed are presented. More extensive studies on the treatment of invasive cervical carcinoma should be done. But, what is more important, the detection of the pre-clinical stage of cervical carcinoma should be advocated so as to prevent invasive carcinoma. For the purpose of detecting pre-clinical carcino , cytologic examination which is highly accurate, particularly in squamous cell carcinoma (accuracy according to Brewer: 95%), should be used periodically, at´ least once a year.
2)´ Cytologic examination ´ is useful and convenient to confirm malignancy with in a few hours in comparison to paraffin preparation´ of the tissue.
3) Cytologic examination is mandatory to detect´ cervical carcinoma in incomplete vaginal atresia and cervical canal carcinoma, which is difficult to be noted by speculum examination.
4) In the case of a cervical lesion which seems to be cervical erosion in appearance and forms hard induration to the parametrium, cytologic examination is decisive in differentiating whether it is inflammatory or carcinomatous in nature.
