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.

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.

This book presents the basic concepts for understanding and practicing breast pathology in routine practice. It explains how to tackle the diagnosis, emphasizing diagnostic clues for each entity as well as pitfalls and mimickers. Each chapter has concise, relevant text illustrated by numerous high-quality pictures highlighting the pearls and challenges in the diagnosis of breast lesions. Experts from around the world describe common and rarer conditions affecting the breast. Histology, immunohistochemistry, cytology, radiology and key morphologic criteria are covered. The book includes a chapter dedicated to breast normal histology, which is very important for understanding breast pathology, and a separate chapter for breast radiology, which is essential in understanding and diagnosing the breast lesions especially in a multidisciplinary team. Also, there is a chapter with the latest TNM staging system as well as the recently revised World Health Organization classification of breast tumors. Since in many breast units the cytology is still used to diagnose breast lesions there is a chapter dedicated to this technique. This book is aimed at trainees and practicing pathologists in surgical pathology, particularly those with an interest in breast pathology and those tackling the daily sign-out.

This book is the culmination of approximately 15 years of experience in breast cytology, which includes the reporting of over 30,000 breast cytology specimens. The cytology of all aspects of the breast is covered, from normal breast with its variations, through benign lesions, both non-neoplastic and neoplastic, to the various types of malignancy, and including male breast. As the primary purpose of any diagnostic procedure on the breast is to detect or rule out malignancy, detailed discussion of breast carcinoma is included. Fine-needle aspiration cytology is dealt with in great detail, from procurement of specimen to preparation and staining of samples. Reporting categories are discussed in depth, with examples of the types of lesion that may be found in each category. Lavish illustrations in full color are included for almost all lesions as pictures illustrate cytologic features much more clearly than do verbose descriptions. Knowing the incidence of a particular entity does not necessarily help in its diagnosis, whereas seeing the morphological features usually leaves a lasting impression. A summary of the cytologic features is included under each topic. Pitfalls that may be encountered are also detailed. The detection of breast cancer is a multidisciplinary endeavor, therefore mammographic and ultrasound images as well as histologic counterparts of the lesions are included, giving the reader a comprehensive view of breast disease.

This book provides a detailed update on all aspects of fine-needle aspiration cytology of breast lesions. It will serve readers as an up-to-date reference and atlas on both new entities in breast pathology, including borderline lesions such as flat epithelial atypia, and the classic benign and malignant lesions. Throughout, emphasis is placed on the characteristic diagnostic features as well as the common pitfalls faced by cytologists. As cytologic features can be highly variable, corresponding cytology and histology images are displayed together, enabling readers to gain a good understanding of the morphologic features of various lesions. Core-needle biopsy and fine-needle aspiration cytology are compared in depth, with attention to their relative strengths and weaknesses and indications. In addition, the impact of molecular classification of breast cancers on cytologic diagnosis is explored, and the use of molecular techniques in diagnostic cytology is discussed.

Catch all the nuances of how pathological lesions present through over 400 full-color illustrations. Practice with confidence and overcome your toughest challenges with advice from the top minds in breast pathology. Apply the latest molecular diagnostic techniques to recognize newly identified classifications in breast disease. Get more of the information you need from new and expanded chapters covering a broad range of diseases and topics including fine needle aspiration cytology and the physical handling of core biopsy specimens; handling and evaluation of sentinel lymph nodes; diseases of the male breast; and state-of-the-art coverage of molecular advances in malignant breast disease. Prepare for the future of breast pathology with a new chapter dedicated to gene profiling and stem cell diagnostic techniques.

Advances in molecular and genetics based diagnostics are driving an increased interest in cytopathology as cytological specimens are the ideal substrate for this new technology. This book fulfills the need for an easy-to-use and authoritative synopsis of breast cytopathology. The volume fits into the lab coat pocket and is ideal for portability and quick reference. Each volume in the series is heavily illustrated with a full color art program, while the text follows a user-friendly outline format.
