Serous tumors of the ovary: ultrastructural observations.
One borderline primary serous ovarian tumor and six carcinomas were studied by means of electron microscopy. Borderline malignant tumor evidenced concomitant presence of both benign and malign serous epithelium. Ultrastructural observations revealed differentiation characteristics which involved complex architecture of cell arrangement and polarity in the distribution of the organelle and intercellular junctions. The cilia believed to be more frequent in benign tumors were also reported in poorly differentiated carcinomas and so may not be considered as reliable prognostic markers.
