This volume in the Essentials in Cytopathology book series will focus on the cytopathology of lymph nodes. It will address the topic of fine needle aspiration of lymph nodes and fulfill the need for an easy-to-use and authoritative synopsis of lymph node cytopathology. The book with adopt an algorithmic diagnostic approach, starting from the cytomorphologic pattern of the lymph node aspirate. The focus will be on the appropriate and effective use of ancillary studies (immunohistochemistry, flow cytometry, fluorescence in situ hybridization and molecular techniques) and integration of their results into the final diagnosis. The book will present the cytopathologic features and differential diagnoses for the major cytologic patterns in lymph node fine needle aspiration. The entities typically falling within each of these patterns will be discussed with illustration of the spectrum of cytologic features, differential diagnoses and pitfalls. The book will cover the full spectrum of benign and malignant primary conditions of the lymph nodes, with emphasis on common disorders. Discussion of metastatic conditions will be restricted to those that are relevant to the differential diagnosis of primary lymphoid disorders. This book is designed as an easy to use resource that fits into the lab coat pocket, ideal for portability and quick reference. It is heavily illustrated and contains useful algorithms that guide the reader through the differential diagnosis of common and uncommon entities encountered in lymph node aspirates. The accompanying text follows an easy to use pattern-based outline. A useful resource for every pathologist, cytopathologist, fellow and trainee.

This book provides current information for a judicious use of conventional and molecular ICC markers performed in cytologic samples to help in the cost-effective diagnosis of superficial and deep-seated masses. By providing both an eminently practical information for appropriate technical preparation of cytologic samples and a systematic exposure of the immunophenotypic and biomolecular characteristics of normal and pathological cells, the reported morphological-molecular findings highlight the characteristics of different lesions that are useful for the practical solution of a particular differential diagnosis. Chapters include description of the cytomorphology followed by a practical ICC staining pattern for each entity. Cytologic materials include serous effusions, exfoliative cytology, fine needle aspiration cytology of superficial and deep-seated masses, and squash preparation from central nervous system masses. Practical Immunocytochemistry in Diagnostic Cytology serves as a valuable resource towards understanding critical differences between tests performed on tissue samples and those carried out on cytologic samples.

This text provides a comprehensive review of the cytology of disease processes of the mediastinum and mediastinal lymph nodes with emphasis in lung and gut nodal cancer staging in specimens obtained by EUS-FNA. This book also reviews the cytology of intramural masses of the gastrointestinal tract using a pattern-based diagnostic approach. The cytomorphology of lesions obtained by EUS-FNA is peculiar by the common presence in the obtained sample of normal luminal gastrointestinal contents, and the cytopathologist should be familiar with this pattern not often seen when the sampling is done by percutaneous approach. Technical considerations pertaining to the operator performing the procedure as well as to the cytopathologist, with emphasis on rapid on-site interpretation are also covered. Most lesions described in the book also have endoscopic US image correlation. Cytology of the Mediastinum and Gut is a useful and practical guide for cytological interpretation and differential diagnosis of lesions obtained by EUS-FNA of mediastinum and gut. All chapters are written by experts with many years of experience in the field and contain the cytology, immuno-profile, molecular profile, and ultrasound features of the masses described.

The Essentials in Cytopathology book series fulfills the need for an easy-to-use and authoritative synopsis of site specific topics in cytopathology. These guide books fit into the lab coat pocket and are ideal for portability and quick reference. Each volume is heavily illustrated with a full color art program, while the text follows a user-friendly outline format.

"Central Nervous System Intraoperative Cytopathology" covers the full spectrum of benign and malignant conditions of the CNS with emphasis on common disorders. The volume is heavily illustrated and contains useful algorithms that guide the reader through the differential diagnosis of common and uncommon entities encountered in the field of intraoperative neuro-cytopathology. "Central Nervous System Intraoperative Cytopathology" is a valuable quick reference for pathologists, cytopathologists, and fellows and trainees dealing with this exigent field.
