Abstract
Objective : The cytological characteristics of ovarian cancer cells found in endometrial cytology were evaluated.
Study Design : Clinicopathological data from 9 ovarian cancer cases with positive endometrial cytology were summarized and the cytological features were compared with primary endometrial cancer cases.
Results : The cell clusters of ovarian cancer found in endometrial cytology were recognized as small spherical clusters with normal endometrial cells regardless of the histological type. The maximum diameters and sizes of cell clusters in ovarian cancer were distinctly smaller than the clusters in primary endometrial cancer.
Conclusions : In endometrial cytology, ovarian cancer cell clusters were significantly smaller than endometrial cancer cell clusters.
