Study on the morphology and reproducibility of the diagnosis of endometrial lesions utilizing liquid-based cytology.

Background: The objective of the current study was to determine the diagnostic cytomorphologic criteria for liquid-based cytology and to evaluate the reproducibility and usefulness of the cytologic diagnosis in endometrial lesions.

Methods: A total of 162 direct endometrial samplings taken from postmenopausal women were evaluated by 2 skilled cytopathologists in endometrial cytology. The cytologic diagnosis was made according to the 1994 classification scheme of the World Health Organization.
