This text provides a comprehensive review of the most frequently encountered diagnostic pitfalls in thyroid cytopathology. Written in a case study format, the text provides the most current and complete information on both non-neoplastic and neoplastic thyroid conditions. Each chapter focuses on a specific diagnostic challenge and/or pitfalls that help in the differential diagnosis as well as the judicious use of ancillary studies when necessary. A review of the current literature as it relates to each disease entity is also incorporated into respective chapters. Highly illustrated with ample illustration of microscopic features to tackle common and uncommon diagnostic challenge in everyday routine practice. This book provides a concise yet comprehensive summary of the common cytologic features needed to resolve the diagnostic pitfalls. Common Diagnostic Pitfalls in Thyroid Cytopathology serve as a very useful resource for pathologists and physicians dealing with, and interested in the thyroid.

This book offers a comprehensive guide to thyroid fine needle aspiration (FNA) cytology. Borderline/precursor tumors, which were introduced in the 4th edition of the WHO classification of thyroid tumors, are also incorporated. In this second edition, prominent international experts discuss the different approaches to thyroid FNA cytology employed in various countries such as Australia, Canada, China, Korea, Portugal, Switzerland, Taiwan, Thailand, Turkey, Ukraine, the USA, UK, Italy and Japan. The book not only covers key principles of thyroid cytopathology but also addresses technical aspects such as procedural complications, liquid-based cytology, immunocytochemistry, staining procedures, and potential pitfalls. Case-based descriptions and clinical findings, radiologic imaging, cytology, and histopathologic diagnosis – all complemented by a wealth of detailed photographs – will help reader understand and overcome many common dilemmas in daily practice. As such, the book represents an indispensable reference work for all cytopathologists, especially those practicing thyroid cytopathology.

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.

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 updated edition remains the essential text for pathologists seeking to make accurate diagnoses from the vast number of differentials.

This practical text and color atlas tells the story of 350 patients, covering a wide range of thyroid lesions with high quality composite images that correlate cytology with histology, and radiology with pathology. Each case includes clinical presentation and final pathology. Concise, easy-to-read text enables readers to quickly find the information they need for accurate diagnosis. 'Lookalike' lesions are grouped together so the subtle cytological differences can be appreciated. The author's practical approach explains mistakes made and lessons learned, so diagnostic pitfalls can be avoided. Triage algorithms and over 2000 printed photomicrographs are provided. The print book is accompanied by a CD-ROM offering images in downloadable format. Written by a leading cytopathologist who has performed onsite assessment for over 10,000 ultrasound-guided thyroid fine needle aspirations, this is an important resource for all healthcare professionals dealing with thyroid patients, including cytopathologists, surgical pathologists, cytotechnologists, sonographers, radiologists, endocrinologists and surgeons.

This book provides cytopathologists a succinct but comprehensive reference covering common diagnostic dilemmas caused by normal, iatrogenic, inflammatory and reactive/reparative changes in cytology samples. This book will provide immediate access to these confounders, clearly illustrating key features and detailing the pitfalls these cells engender in all cytologically accessible body sites. The text is organized in chapters corresponding to cytologically accessible body sites/organ systems. Each chapter’s discussions are further organized by general categories of confounders (i.e., normal contaminants, inflammatory, infectious and iatrogenic), with special attention to site specific confounders. Pitfalls in Diagnostic Cytopathology With Key Differentiating Cytologic Features will be of great value to practicing pathologists, pathology residents, cytopathology fellows, cytotechnology technologists and students.
