A case of NSOC syndrome revealed by cervical smear screening in mass surveys was presented. The patient was a 50-year-old woman who had not complained of any problem. In cytology, tumor cells could be seen as a cohesive and overlapping cluster in a clean background and papillary adenocarcinoma originating from ovary or Fallopian tube was considered. We would like to emphasize that the rare NSOC syndrome always should be considered in the examination of cervical smears.
