Criteria for their diagnosis, in particular for the evaluation of extraovarian disease (implants) are not well defined and not consistently applied. Accordingly, pathologists in practice find this an extremely difficult area. Hence this topic was selected. Borderline ovarian tumors have not been the subject of a symposium for over ten years. The objective is to review the current understanding of the pathogenesis and behavior of borderline ovarian tumors and to review criteris for diagnosis of the primary ovarian tumor and the implants.
