Borderline ovarian tumors: Diverse contemporary viewpoints on terminology and diagnostic criteria with illustrative images

The National Cancer Institute sponsored a Borderline Ovarian Tumor Workshop held in August 2003 in Bethesda, MD. This report was developed from discussions at the Workshop. The participants acknowledged several areas of disagreement on basic terminology issues and agreed that a glossary with example images would help clarify many commonly misunderstood issues. This report defines terminology used in the pathological description of borderline tumors and their variants, and illustrates examples of each of the most common entities. It also addresses controversial aspects of the definitions and issues involving specimen handling and reporting. For those issues where there is disagreement, the terminology and diagnostic approaches reflecting the differing views are presented. (C) 2004 Elsevier Inc. All rights reserved.
