The goal of this volume in the series Foundations in Diagnostic Pathology is to offer a textbook with a novel perspective on the many aspects of gynecologic pathology as refl ected by the diversity of the contributors, who not only represent the “younger generation” in this fi eld, but also have a breadth of experience from around the world. This book is not meant to be all inclusive, but rather focuses on the most common as well as some of the most challenging entities of gynecologic pathology. In contrast to other gynecologic pathology textbooks which cover diseases of the female genital tract in a traditional manner, the most notable and defi ning feature of this book is the accompanying Clinical and Pathologic Fact Sheets, which allow quick access to the main highlights of a particular disease. This textbook is aimed primarily at pathology residents and fellows in training as well as all who would like a comprehensive, “user-friendly” overview of this discipline.
