The Bethesda System for Reporting Cervical Cytology

Definitions, Criteria, and Explanatory Notes
It has been over 10 years since The Bethesda System (TBS) has been updated and revised.  The American Society of Cytopathology (ASC) has taken the lead in developing the third Bethesda Atlas which will (1) expand the breadth of images (particularly for liquid based preparations); (2) address several clinicocytopathologic issues that have arisen in clinical practice; and (3) incorporate the concept of risk-based management which served as the basis for the most recent American Society for Colposcopy and Cervical Pathology management guidelines.  These updates, while important, will not result in major changes to the terminology and do not warrant a full Bethesda Workshop. Under the leadership of Drs. David Wilbur and Ritu Nayar, each atlas section will be updated with new references and images.
