This text describes a system of reporting breast fine needle aspiration biopsy that uses five clearly defined categories, each described by a specific term and each with a specific risk of malignancy. The five categories are insufficient/inadequate, benign, atypical, suspicious of malignancy and malignant. Each category has a risk of malignancy and is linked to management recommendations, which include several options because it is recognized that diagnostic infrastructure, such as the availability of core needle biopsy and ultrasound guidance, vary between developed and low and middle income countries. This text includes key diagnostic cytological criteria for each of the many lesions and tumors found in the breast. The cytopathology of specific lesions is illustrated with high quality photomicrographs with clear figure descriptions. Chapters also discuss current and potential future ancillary tests, liquid based cytology, nipple cytology and management. An additional chapter provides an overview of an approach to the diagnosis of direct smears of breast fine needle aspiration biopsies. The International Academy of Cytology Yokohama System for Reporting Breast Fine Needle Aspiration Biopsy Cytopathology provides a clear logical approach to the diagnosis and categorization of breast lesions by FNAB cytology, and aims to facilitate communication with breast clinicians, further research into breast cytopathology and related molecular pathology, and improve patient care.

This atlas is the offspring of the “The National Cancer Institute (NCI) Thyroid Fine Needle Aspiration (FNA) State of the Science Conference,” hosted by the NCI and organized by Dr. Andrea Abati. Preparations for the conference began 18 months earlier with the designation of a steering committee and the establishment of a dedicated, p- manent web site. The meeting took place on October 22 and 23, 2007 in Bethesda, Maryland and was co-moderated by Susan J. Mandel and Edmund S. Cibas. The discussions and conclusions regarding terminology and morphologic criteria 1, 2 from the meeting were summarized in publications by Baloch et al. and form the framework for this atlas. The atlas is organized by the general categories of “Nondiagnostic,” “Benign,” “Follicular Neoplasm/Suspicious for a Follicular Neoplasm”, “Suspicious for Malignancy,” and “Malignant,” and it includes the defi- tions and morphologic criteria of these categories as set forth by Baloch et al. The majority of the conference participants also agreed on a category of “undetermined significance,” which is incorporated in this atlas (Chap. 4). It is critical that the cytopathologist communicate thyroid FNA interpretations to the referring physician in terms that are succinct, unambiguous, and helpful clinically. We recognize that the terminology used here is a flexible framework that can be modified by individual laboratories to meet the needs of their providers and the patients they serve.

In the era of precision medicine, physicians are increasingly in need of more definitive diagnostic, prognostic, and predictive information derived from small biopsy specimens such as cytology samples in order to guide effective patient care. Cytopathology is well poised to meet this challenge. Whilst the traditional cytomorphologic component of cytology practice is still valid, enormous advances have been made in the field of cytopathology thanks to transformative technology and innovative individuals that have augmented the cytologists' ability to meet the demands of modern medicine. The purpose of this book is to describe, illustrate, and review many of the most recent developments regarding modern techniques employed in cytopathology. This latest monograph is intended for all cytologists including cytopathologists, cytotechnologists, cytology lab assistants, trainees, research scientists, and anyone who is interested in the field of cytopathology. We have invited pioneering experts in their respective fields to author these chapters. This book is not only the culmination of their groundbreaking work and effort but also presents a critical review of the current literature. We have attempted to provide readers with an informative and comprehensive aid so that they may better appreciate how emerging technology has been applied to cytology. Each chapter in this book presents a stand-alone contemporary review of emerging topics in cytopathology. We hope that you will find this monograph thought-provoking and a valuable reference for your practice.

The Second Edition of The Milan System for Reporting Salivary Gland Cytopathology, like the First Edition, represents a collaborative effort by a multidisciplinary group of cytopathologists, surgical pathologists, molecular pathologists, radiologists, and head and neck surgeons. This international group shares the goal of creating a practical and uniform reporting system for salivary gland fine needle aspiration (FNA). This book is organized into six general diagnostic categories: “Non-Diagnostic,” “Non-Neoplastic,” “Atypia of Undetermined Significance (AUS),” “Neoplasm: Benign,” “Neoplasm: Salivary Gland Neoplasm of Uncertain Malignant Potential (SUMP),” “Suspicious for Malignancy,” and “Malignant.” It includes definitions, morphologic criteria, and explanations for each of the diagnostic categories. Specific chapters are dedicated to the application of the latest available ancillary studies, radiologic features of salivary gland lesions, clinical management, and histological considerations including updates from the most recent 5th Edition WHO blue book. The Milan System for Reporting Salivary Gland Cytopathology 2nd Edition represents an essential step towards increasing the overall effectiveness of salivary gland FNA and fostering better communication between clinicians and between institutions to improve overall patient care.

This book introduces basic ROSE techniques and resources required to set up ROSE service. It reviews the cytomorphologic features that are recognizable during ROSE, including those important for sample adequacy, specimen triage, preliminary interpretation, and potential diagnostic pitfalls. Economic and regulatory aspects are discussed as well as the pros and cons of telecytology. The book is formatted for clinical settings, simulating the ROSE process that occurs in the ultrasound room, CT room, bronchoscopy suite, and endoscopy suite. Each chapter focuses on the cytomorphologic clues and pitfalls of the entities specific to that clinical setting. Rapid On-Site Evaluation: A Practical Guide will be a valuable resource for pathologists, cytotechnologists, physicians who perform biopsies and/or ROSE evaluation, and trainees for utilizing ROSE and improving diagnostic performance of biopsies.

This book is the culmination of an international effort to bring consistency and diagnostic efficiency to effusion cytology for the sake of patient care. The authors recognize special challenges in serous fluid cytopathology, such as reporting the presence of Mullerian epithelium in peritoneal fluids. What is an appropriate serous fluid volume to ensure adequacy? How should mesothelial proliferations be reported and is it appropriate to make an interpretation of malignant mesothelioma? How specific should a report be regarding the origin and subtyping of tumors found in serous fluids? What are the appropriate quality monitors for this specimen type? Special chapters on considerations for peritoneal washings, cytopreparatory techniques, mesothelioma and quality management are included to address these issues. The text contains literature reviews that elucidate existing evidence in support of current practices and recommendations. Expert opinions on where evidence was lacking, the most common practices were adopted by consensus, and where there was no commonality, are employed. Written by experts in the field, The International System for Serous Fluid Cytopathology serves as a collaborative effort between the International Academy of Cytology and the American Society for Cytopathology and calls upon participation of the international cytopathology and oncology communities to contribute to the development of a truly international system for reporting serous fluid cytology

Breast cytopathology is a field characterized by practicality and diagnostic efficacy. This book focuses mainly on morphology, with helpful hints for recognizing benign lesions and the main features of malignancy. It reviews specific features of various lesions and the consequences of the diagnosis for the management of the patient. Each chapter contains high-quality cytology images accompanying the descriptions, including comparison images to distinguish the most important morphological features and to help in the differential diagnosis. Fine needle aspiration cytology (FNAC) sampling and preparation technique, fixation, staining, and principles of its interpretation are covered. Immunocytochemistry and ancillary techniques are outlined, as well as the main clinical and radiological features of breast lesions, and the cytological diagnostics of axillary lymph nodes. This publication will be of great use to medical practitioners in their first approach to breast cytopathology, as well as to pathologists and cytotechnicians with little to moderate experience in the field.
