Foreword
Only once in a while does a pathology book arrive on the scene that all diagnostic pathologists should own. Color Atlas of Pulmonary Cytopathology, by Sudha R. Kini, MD, is such a book. It can best be described as concise yet detailed. There is more useful information packed into its 15 chapters than seen in most books three times its size. Thus it gives me a great pleasure to contribute this foreword.
As I reviewed the manuscript prior to writing this Foreword, I was impressed by many unique features that I would like to share with you. The chapter covering the standard cytopreparatory techniques, specimen procurement methodology, and staining techniques contains detailed information that many pathologists once knew but have forgotten. It is a good refresher course and reference resource. Near the beginning of this chapter, Dr. Kini states a fact weil known to experienced diagnostic pathologists, namely that communication between pathologists and clinicians is essential. It is akin to a favorite saying of one of my partners that the best special stain in pathology is a telephone call to the appropriate clinician. This chapter also contains especially useful information on the expected diagnostic yield from various specimen types, for example, FNA, BAL, and wh ich type of specimen is most useful for making a specific diagnosis.
Another chapter discusses tli.e anatomy, histology, and cytology of the normal components of the lower respiratory tract. The tables in this chapter are representative of the superb tables throughout this book. They are packed with detailed useful information and are easy to refer to.
One of my favorite chapters discusses nonneoplastic lesions. Perhaps this is because as the longer one practices diagnostic pathology, the more one realizes the difficulties in differentiating reactive nonneoplastic cells and tissue process from malignant ones. This chapter should be required reading for all pathology residents and pathologists. It also illustrates the extensive experience of Dr. Kini has and her exceptional understanding of the morphogenesis of disease processes as weil as clinical features associated with such diseases. This chapter contains many pearls.
Several chapters dealing with the cytopathology of common and uncommon lung neoplasms have a standard format consisting of an introduction of the gross and histologie features of a given tumor followed by a detailed discussion of the cytopathologic findings. Specimens most likely to obtain diagnostic cells are discussed.
The seetion on differentiating adenocarcinoma from epithelial mesothelioma is especially straightforward, detailed and honest. It provides the reader with a background and puts the cytopathology aspects in perspective. There is extremely useful information in all these chapters about specificity and sensitivity of cytologic findings and differential diagnoses.
There is useful immunohistochemical and ultrastructural information throughout the book. The book contains detailed chapters on the histology and cytopathology

of Iymphoproliferative lesions of the lung and an unusual amount of detail on metastatic neoplasms to lung.
This book contains so mush useful information that it could have been written without a single illustration. That is not the case however and, in fact, the color photographs are numerous and the quality is the best I have seen in any pathology book. As a result, this book will serve as a companion volume to another SpringerVerlag publication, Pulmonary Pathology, where due to size constraints, the chapter on pulmonary cytopathology had to be eliminated in current edition.
A Color Atlas of Pulmonary Cytopatholgy is a book that should not only be on the desk of all cytotechnologists/cytopathologists, but also on the desk of all pathologists/surgical pathologists and pulmonologists. This atlas reveals what many diagnostic pathologists already know, namely that cytopathology provides a superb insight into the morphology of neoplastic and nonneoplastic lung disease.

Foreword
Preface
The purpose of this atlas is to provide a comprehensive, pictorial resource of pulmonary cytopathology. Although pulmonary cytopathology is enriched with myriad of individual case reports, review articles, seminars, and monographs on an individual topic or topics, there is not currently a single text devoted entirely to all of its fractions with adequate illustrations. More than two decades have passed since the book Diagnostic Respiratory Cytology, by W.W. Johnston and W.J. Frable, was published, and more than one decade since D.L. Rosenthal's monograph, Cytopathology of Pulmonary Diseases. Both are still excellent references. The last few years have seen several publications of atlases; however, they encompass only aspiration cytopathology of lungs and other thoracic organs. The chapters on pulmonary cytopathology in some of the newer textbooks are excellent but limited by the small number of illustrations. With major advances in our understanding of lung cancers, the addition of newer diagnostic entities, revised classifications of lung tumors, and newer diagnostic techniques, there appeared to be a need for all of this information to be under one cover.
I have compiled this atlas with that in mind by including the current information in both exfoliative and aspiration cytopathology, both of malignant neoplasms as weIl as of nonneoplastic lesions, infections, and pulmonary involvement in immunodeficient and immunosuppressed patients, as weIl as pulmonary cytopathology in neonatal and pediatric age group. I have tried to provide liberal illustrations of common lung malignancies as weIl as of unusual and uncommon ones, so that the reader does not have to search the literature when confronted with an unusual case. Because I did not have many of these unusual cases in our files, I am immensely grateful to my professional colleagues-Iocally, within the United States, and globally-who readily responded to my request for glass slides or images. I have also focused on nonneoplastic entities, including noninfectious and infectious disease processes, that often demonstrate cytologic changes in respiratory specimens. Bronchoalveolar lavage has gained tremendous popularity because of its success in the detection of infectious agents, especially in immunocompromised patients. Many of the nonneoplastic disease processes described in this text mandate that the final diagnoses be established by means other than cytology, and rightfully so. The cytologic changes, however, can often provide clues for further investigations.
I have opted to discuss only primary intrapulmonary malignancies in this atlas, thereby excluding pleural diseases and tumors, specifically malignant mesotheliomas. The decision was made because malignant mesothelioma could not be discussed alone without devoting an entire chapter to pleuraliesions. I feIt this to be beyond the scope of the atlas; however, diffuse malignant mesothelioma has been discussed and illustrated in considerable detail in the differential diagnoses of ade-
ix
x
nocarcinomas. The sarcomatous variant is also discussed, along with spindie celllesions of the lung. I do hope that omission of a chapter devoted to mesothelial lesions will not detract from the completeness of this atlas.
No publication in pathology is complete without discussions on diagnostic accuracy and pitfalls. I have tried to emphasize the differential diagnoses in every chapter and attempted to highlight the cytologic differences in tables and in illustrations.
The chapter on cytopreparatory techniques is rather comprehensive. No one will disagree with the fact that proper cytologic evaluation and diagnostic interpretation is directly proportional to the quality of the prepared and stained smears. The illustrations in this atlas can attest to it. I hope that the information provided in that chapter will help those who are facing difficulties in cytopreparation. As far as choice of fixation and staining is concerned, Papanicolaou is fortunately the standard method for exfoliative cytology and will not cause any debate. The preferred staining method for fine needle aspiration biopsies is a different issue. I have always been a proponent of Papanicolaou stain, which explains why most of the images presented in this atlas are wet-fixed and stained by Papanicolaou method.
The value of any atlas depends on the quality of its color images. The credit for these goes entirely to Ms. Jane Purslow for her excellence in photomicrography. Her enthusiasm knows no bounds. I will always be indebted to Jane for her encouragement, support, and relentless energy, and for taking hundreds of photomicrographs. I am very pro ud of my cytopathology technical staff, both cytotechnologists and medicallaboratory technicians, for the excellent quality of cytopreparation. Their dedication is unsurpassed. I am very grateful to Dr. Irving Dardick of Pathology Images, Toronto, Canada, for the superb reproduction and color balance of the images. Working with Dr. Dardick is always a very pleasant experience. The art and photography department staff at Henry Ford Hospital has been very gracious, helpful, and cooperative in taking several of the photographs related to cytopreparation. I am truly appreciative of their services. I gratefully acknowledge the secretarial assistance provided by Ms. Laure Porzondek and Ms. Linda Brandt. Ms. Susan Dingler, the education coordinator of Henry Ford School of Cytotechology, was always willing to review the manuscript and offer helpful advice, especially in reference to students' needs. I have always kept the interest of cytotechology students in the back of my mind, and for that reason the text in some chapters is rather quite detailed.
It is my hope that this atlas will be a welcome addition to the field of cytopathology and be useful both to those who practice cytopathology as weil as to those practicing pulmonary medicine.
