In any histopathology department, cutaneous biopsies form the major part of the workload. In many instances these may be readily dealt with by experienced pathologists and their documentation represents an essential step in organising therapy. However, in a number of areas dramatic changes have occurred in dermatopathology. The rapidly changing incidence of pigmented lesions of the skin and the availability of diagnostic cell markers in the complex cutaneous lymphomas have meant that for many pathologists a review in these fields will be valu- able. The distribution and pattern of skin pigmentation may allow us to make important assertions and draw importantconclusions about the genetics of skin disease, but also about human variability. Cutane- ous vasculitis is a difficult problem where clinicopathological consulta- tion is vital in diagnosis and the review presented has been written with this verymuch in mind. In the same way, many diagnostic difficul- ties exist in assessing buttous lesions in the skin and for this reason a review was invited. Finally, our understanding of certain skin diseases has been radical- ly altered by knowledge of the dynamics of the changes seen, a field which has also beenstudied with advantage inother systemsin patholo- gy. This volume is intended as an aide to those many pathologists and dermatologists who, often together, are responsible for the pro- vision of clinical care in this demanding field. London C. L.

Significant progress has doubtlessly been made in the field of cere bral protection compared to earlier centuries, as recently reviewed by Elisabeth Frost (6). She cites the recommendations for treat ment of brain trauma by Areteus, a Greek physician of the second century A. D. He expressed quite modem views with regard to the need for prompt action considering complications that follow even minor symptoms. He advised burr holes for evacuation of hema toma in seizures, the use of diuretics and, most interestingly, also hypothermia. German surgeons of the 17th century had little more to offer than prescriptions of which the most effective constituent was alcohol (10). Thus, Sir Astley Cooper was probably the next surgeon to make noteworthy contributions when advising the use of leeches to the temporal artery and other means of bleeding in stead of surgical intervention in cases of raised intracranial pressure (loc. cit. 6). Although our knowledge has greatly expanded during the last two decades, extensive discussions have led to only few conclusions. Promising results from animal studies were translated to clinical sit uations only to yield controversial and sometimes confusing results. Since the observations of Brierly (5) on ischemic cell damage, im proved information on structural aspects, probably even related to concomitant biochemical studies, should allow the validity of thera peutic concepts to be verified. Investigations on cerebral ischemia have led to the differentiation of synaptic transmission failure and membrane failure."

During the past ten years numerous new findings have been documented in the field of gynecological pathology, especially in respect of neoplasms. These findings have been generated by the application of recently developed techniques of immunology and molecular biology. However, clinicopathologic examinations. are still an absolute requirement for the morphologic evaluation of neoplasms, including gynecological tumors. The International Society of Gynecological Pathologists (ISGYP) has contributed greatly to the progress within gynecological pathology. The ISGYP Nomenclature Committee has promoted the International Histological Classification of Gynecological Tumors under the auspices of the W orid Health Organization. A new edition of the classification of tumors and tumor-like conditions of trophoblastic disease, uterine corpus, cervix, vagina, and vulva is currently in press. A second volume covering the ovaries, fallopian tubes, broad ligament, and female peritoneum will be published later. Organization of scientific symposia and seminars has also been an important activity of the ISGYP. The present editor organized and chaired a symposium entitled "Recent Progress in Diagnostic Pathology of Gynecological Tumors" held in Sendai, Japan on 11 April 1986 in close cooperation with Prof. T. Okagaki, University of Minnesota Medical School, and under the joint auspices ofthe ISGYP and the Japanese Society of Pathology. The following topics were discussed at this symposium: - Immunocytochemistry of gestational trophoblastic disease (Dr. R.J."

Organ transplantation has almost disappeared from headlines in the daily press, possibly because it failed to fulfill exaggerated expectations. Transplanta tion pathology has become more and more important, not only with relation to therapeutic transplantations but even more in its fundamental theories. There is some analogy here to the development in space science where spectacular achievements were followed by sobering frustrations and where, for the time being, the effect on technology is more fruitful than the outcome of the original far-reaching projects. That transplant rejection was defined, in most of its stages, as an immunologic process, has given many new impulses to immunology in general. Transplantation assays have become a pet experiment in immunobiology and an abundant source of general information and knowledge. The implications of such a development could not be predicted when the present volume was outlined and planned. In accordance with the concept of WILLI MASSHOFF, general transplantion pathology was given a central position as a fundamental science, while the chapters on the transplantation of various tissues are of a more paradigmatic character. It was MASSHOFF who invited competent authors and who managed to balance their articles, despite some overlapping, so as to draw a comprehensive picture of contemporary transplanta tion pathology. WILLI MASSHOFF died while he was editing the first manuscripts. As co-editors we have undertaken to complete the publication that we began together."

In 1967 cardiologists in Switzerland were struck by the sudden increase in the number of cases of so-called primary pulmonary hypertensive disease (PPHD). Up untill966, the cardiology centers in Switzerland had not seen more than one or two cases a year, but this number suddenly multiplied by ten or twenty times. At the June 1968 meeting ofthe Swiss Society of Cardiology, Gurtner et al. (1968b) presented a paper which raised the question whether the vascular types of cor pulmonale had increased. They also raised the question about the possible responsibility of environmental factors, such as toxins or drugs, in causing this increase. Krrihenbuhl et al. (1968) first suggested the possible responsibility of anorexigenic drugs, but no proof was provided. Soon after this, the cardiology team in Bem (Gurtner et al., 1968a) published their report, which resumed and completed the above-mentioned prelim inary communication; 31 cases of PPHD, among which 17 had taken an anorexigenic drug, aminorex fumarate (Menocil, Cilag), were reported. The importance of this work was soon recognized and it was followed by several meetings (in Vienna, Hannover, and Burgenstock) and two round tables sponsored by the Swiss Society of Cardiology (in Montreux and Basel)."

Human teratocarcinoma has long held a fascination to the pathologist be- cause of the diversity of the seemingly benign differentiated tissues asso- ciated with the tumor. An understanding of this diversity came with the demonstration of the pluripotent nature of the embryonal carcinoma cell, the stem cell of the tumor, in experimental animals. Single cell clones of murine embryonal carcinomas were derived and the resultant cell lines injected into immunosuppressed hosts, where the embryonal carcinoma stem cell itself gave rise to the wealth of differentiated tissues seen in teratocarcinomas. It was also shown that teratocarcinomas could be pro- duced experimentally by transplantation of staged early mouse embryo to extrauterine sites; subsequent experiments suggested that the embryonal carcinoma stem cell was, in fact, comparable to a normal cell of the em- bryonic ectoderm. Many elegant experiments have since been built on this early work; murine embryonal carcinoma cells are providing the ex- perimental material for a first biochemical evaluation of the earliest dif- ferentiation events in mammalian embryogenesis. In this volume, we relate the beginnings of experimental research on human teratoma. The human embryonal carcinoma cells have been char- acterized and established in vitro, providing an experimental model to study the unique biology of these cells. Monoclonal antibodies, estab- lished from work with these in vitro cultures, provide cell surface probes that define populations of embryonal cells and their derivatives in tumor sections.

Flow cytometry has rapidly evolved into a technique for rapid analysis of DNA content, cellular marker expression and electronic sorting of cells of interest for further investigations. Flow cytometers are being extensively used for monitoring of cellular DNA content, phenotype expression, drug transport, calcium flux, proliferation and apoptosis. Phenotypic analysis of marker expression in leukemic cells has become an important tool for diagnostic and therapeutic monitoring of patients. Recent studies have explored the use of flow cytometry for monitoring hormone receptor expression in human solid tumors and for studies in human genomics. Contributions in the current volume are based on presentations made at the First Indo-US workshop on Flow Cytometry in which experts from USA, UK and India discussed applications of flow cytometry in biological and medical research. This book will be of interest to post graduates and researchers in the fields of pathology, cytology, cell biology and molecular biology.

One would rarely have the opportunity to augment his medical library with a more exhaustive examination of the subject matter than is contained herein. Would only that all areas of one's professional responsibilities be available in such a complete, didactic, written form. Having a decided interest in the subject of head and neck paragangliomas for the past decade, I have had the opportunity to explore the subject through published medical literature and personal investi gation, and feel qualified to commend Doctors Zak and Lawson on their dedica tion, accuracy, and thoroughness in this presentation. One seeking any particular aspect of knowledge from historical to an up-to-date concept on the subject of paragangliomas will find his answer here. Vincent J. Hyams CAPT MC USN Chairman, Otolaryngic Pathology Department Armed Forces Institute of Pathology Washington, D.C. Preface One of us (F.G.Z.) initially became interested in the paraganglionic system when as a resident in pathology at The Mount Sinai Hospital, he performed an autopsy on an elderly woman with an intracranial tumor of the posterior fossa, which extended through the jugular foramen into the neck in a dumbbell fashion."

Hairy cell Leukaemia (HCL) has always attracted an interest out of all proportion to its frequency and continues to do so. There are two reasons for this. The first is that the disease is unusually responsive to therapy and second is that it has provided a number of important insights into B-cell biology. This monograph is a comprehensive account of hairy cell leukaemia and aims to provide a more detailed account than is available in the existing literature. The work is timely because a consensus has now emerged concerning accurate differential diagnosis a nd curative treatment. These aspects therefore form the focus of the book and are considered in detail. The basic advances in the laboratory that encourage the belief that elucidation of the underlying oncogenic event in the disease may be within reach. The background to this belief is extensively renewed. As a result the monograph will be of interest and practical value to both clinicians and researchers in this and related fields.

Patients with advanced breast or prostate cancers usually develop bone metastases. The principal complications resulting from metastatic bone disease are pain, spinal cord compression, pathologic fractures and bone marrow suppression. Improving the management of bone metastases is crucial to quality of life for patients with breast and prostate cancer.

Advances in understanding of the molecular mechanisms underlying the pathophysiology of bone metastasis are driving the development of new therapeutic strategies.

This book describes all human leukemia-lymphoma cell lines that have been established and that grow continuously under standardised in vitro conditions. These lines are derived from cells belonging to all the major hematopoietic cell lineages, i.e. B- and T-lymphocytes, natural killer cells, granulocytic cells and megakaryocytic cells. The clinical data, the culture conditions and the major phenotypic features of the cell lines are described with citations. This book is the first book describing human leukemia-lymphoma cell lines and will be of interest to scientists involved in the areas of hematology, oncology, immunology, molecular biology and cytogenetics. Cancer Cell Lines, Volumes 1-3: These 3 volumes provide a comprehensive text on the culture of established cell lines from every type of human cancer. The volumes provide a basic manual and reference resource for every cancer research scientist using human cancer cells.

Complement has long been regarded as a pivotal effector arm of the innate immune response, eliciting important immunoregulatory functions in the context of inflammation and also serving as a vital link between the innate and adaptive immune response. In the post-genomic era, our knowledge of the innate immune system is enriched by findings that point to novel functions that do not strictly correlate with immunological defense and surveillance, immune modulation or Inflammation. Several studies indicate that complement proteins exert functions that are either more complex than previously thought, or go well beyond the innate immune character of the system. The advent of high-throughput platforms for genome and proteome-wide profiling, together with the enormous amount of raw genetic information that has accumulated in the databases, have stirred new expectations in biomedical research. They have led complementologists to revisit established biological systems, such as the complement system, from a global and integrative perspective. Complement research is now faced with the challenge of trying to integrate isolated biochemical pathways into complex gene and protein regulatory circuits. In this respect, scientists from around the world convened at the Fourth Aegean Conferences Workshop on Complement Associated Diseases, Animal Models, and Therapeutics (June 10-15, 2007), to discuss recent advances in this fast evolving field. This volume represents a collection of topics on the "novel" functions of complement, patho-physiology, protein structures, design of complement inhibitors, and complement assays discussed during the conference.

by CDs, but we continue to utilize the same general format of morning didactics and afternoon glass slide review and small group interactions. One of our biggest successes was in the ever-expanding set of didactic lecture notes and radiologic, gross, microscopic, ultrastructural, and other images that course participants received, so it wasn't much of a surprise when we were approached by the publisher to consider creating an updated compilation of some of the best talks and packaging them in a monograph available to a broader population of physicians and scientists. With the extraordinary attention to detail that he is known for, my co-editor David Chhieng has been both the brains and the brawn of this project, resulting in the bringing together of such a collection while trying to be sensitive and representative of the various branches of pathology reflected in the actual course. From surgical pathology, chapters cover select topics in endocrine, gynecologic, GU, and GI pathology with contributions from Walter Bell, Michael Conner, Katrin Klemm, and Audrey Lazenby, respectively. Tom Winokur has begun to prepare us for the near future with a treatise on molecular markers in breast cancer. The interactive nature of cytopathology and surgical pathology are brought together by Claudia Castro [now at the U. T. Medical Branch at Galveston] and David Chhieng in three chapters covering mediastinal, pleural, and pulmonary pathology.

The annual research conference for 1996 of the American Institute for Cancer Re search was again held at the Loews L'Enfant Plaza Hotel in Washington, DC, August 29 and 30. The topic for this, the seventh in the series, was "Dietary Fat and Cancer: Genetic and Molecular Mechanisms. " Two separate presentations were given as the conference overview. "Fat and Cancer: The Epidemiologic Evidence in Perspective" noted that die tary fat can be saturated, largely from animal or dairy sources, or mono- or polyunsatu rated, mostly from plant sources. Unlike animal fats, fish contain relatively high levels of protective omega-3 fatty acids. Although the hypothesis that dietary fat is associated with cancer is plausible, the mechanisms involved are reasonable, and many animal studies support the hypothesis, there are many obstacles in any direct extrapolation to humans, in cluding imprecise measures of dietary fat intake, variability in individual diets, and spe cies variations. Despite these limitations, there is a weak positive correlation between colon cancer and dietary fat intake, but with substantial differences for various ethnic groups. In the case of breast cancer, there is substantial variation among countries and eth nic groups, but the overall evidence indicated an association with fat in the diet. Epidemiologic studies of dietary fat and prostate cancer are more consistent and most show a positive relationship. However, it was not clear which types of dietary fat were im plicated in the effect."

Essentials of Autopsy Practice updates the modern pathologist on issues related to the autopsy. This volume contains topical chapters on the pathology of shock, religious attitudes to death, incised wounds, radiological investigations, metabolic disorders in childhood, maternal deaths, body alterations and piercings which are comprehensive, unique and educational. It brings the literature together into a modern, up-to-date review of the subject, each authored by experts in their field. It comprises the most recent developments in current autopsy practice making the book unique and exceptional - a valuable aid for the bench top, autopsy suite, laboratory or library. A hands-on reference book, Essentials of Autopsy Practice is of interest to both trainees and consultants in all sub-branches of pathology including forensic pathology. It can also be used by non-medical staff involved in the dead, such as nurses, police, lawyers and bereavement officers.

Decoding the significance of proteinuria as an indicator of severity or prognosis in kidney disease is a stimulating challenge to students and practitioners of nephrology. Sir Richard Bright in 1827 associated pro with the disease that bears his name. In the subsequent more teinuria than a century and a half, however, the meaning of the linkage between proteinuria and renal disease remains elusive. Proteinuria is discovered on routine urinalysis in about 10 million Americans, most of whom express no symptoms of kidney disease, each year. From the studies of Robinson (updated in these pages), we know that proteinuria, per se, can be present for 20 years without change in re nal function, as described in orthostatic proteinuria. By contrast, pro teinuria may be the harbinger of swift kidney destruction, rarely cul minating in clinical collapse, a syndrome typifying "malignant proteinuria" as detailed herein by Avram. Although proteinuria is ubiquitous, an orderly management strategy for rational handling of proteinuria of less than nephrotic range is lack ing. Separation of tubular proteinuria and transient proteinuria of fever is now possible routinely. This book provides a record of the contribu tions of investigators and clinicians whose work forms the substrate for production of understanding and, ultimately, marching orders for prac titioners seeking optimized management for their proteinuric patients."

Over the last few decades new data on the distribution, pathogenicity, diagnosis, treatment and control of trematode infections and diseases in man and animals, including zoonotic trematodiasis, have emerged from various geographical regions. These new data are compiled in this book together with existing information to fulfil the present need. Seven major trematode-induced disease groups, namely, schistosomiasis, paragonimiasis, fascioliasis and fasciolopsiasis, dicrocoeliasis and eurytremiasis, clonorchiasis and opisthorchiasis, paramphistomiasis, and diseases due to intestinal trematode infections are dealt with in this book. These diseases still rank as a major cause of morbidity and mortality - both in man and in livestock - mainly in the tropics, and contribute to the socio-economic problems. Many of these diseases are also zoonoses, some major and others potential. The intended readership of this treatise include postgraduate students of medical and veterinary parasitology, research workers as well as medical practitioners, veterinarians, tropical diseases specialists, veterinary public health specialists and teachers concerned with trematode infections and trematodiasis of man and animals.

Dr. Peter S. Conti is a Professor of Radiology and the Director of the PET Imaging Science Center at the University of Southern California, and is a Fellow of both the American College of Radiology and American College of Nuclear Physicians. He is a pioneer in the development of the clinical applications of PET and more recently PET-CT. He and one of his fellows, Dr. Daniel Cham, have published this groundbreaking PET-CT case-based book, which reveals how PET-CT can be applied in routine clinical scenarios. Leading authorities in the field examine a wealth of heavily-illustrated original PET-CT cases that showcase both common and uncommon cancers, and the latest PET-CT applications for neurological and cardiovascular disorders. Correlative three-dimensional cross-sectional PET and CT images highlight pathological findings. Each of the clinical applications is accompanied by a concise explanation of the patient history and interpretation of the PET-CT study. Insightful discussions and "pearls and pitfalls" are included to assist in a better understanding of pathology, diagnosis, and imaging approaches. Readers also find important coverage of pathophysiology and technical artifacts. This unique book is ideal for nuclear medicine practitioners, radiologists, and residents, as well as referring clinicians interested in learning more about how this new medical imaging technology can be applied in their patient populations.This unique book is ideal for nuclear medicine practitioners, nuclear medicine residents, and clinicians interested in medical imaging for tumor patients.

In "Inflammation in the Pathogenesis of Chronic Diseases: The COX-2 Controversy," a worldwide panel of leading experts discusses the role of inflammation in the pathogenesis of major chronic diseases and the current controversy regarding risk versus benefit of selective cyclooxygenase-2 (COX-2) inhibitors. This volume is intended for scientists in medicine, epidemiology, pharmacology, molecular biology, and related fields. The authors provide exciting and enlightening perspectives on COX-2 and related molecular targets in the future of medicine, including historical perspectives on the discovery and development of aspirin, ibuprofen, and compounds that selectively inhibit COX-2, and the potential for development of new compounds with better efficacy and safety in the 21st century. Specfic chapters illuminate the role of inflammatory mechanisms in the pathogenesis of arthritis, cardiovascular disease, cancer, neurodegenerative disease, diabetes mellitus, obesity, and other life-threatening and debilitating conditions. Experts in cardiovascular medicine explore the "COX-2 controversy" regarding adverse effects of some (not all) selective COX-2 inhibitors on the cardiovasculature. Recent findings suggest that cardiovascular risk associated with some COX-2 inhibitors may not be due to a class effect, but rather depends upon the molecular structure of specific compounds. Important findings are documented in cancer research showing that selective COX-2 inhibitors have powerful antineoplastic effects against major forms of cancer. A special section explores the current evidence supporting the role of COX-2 and inflammation in the development of Alzheimer s disease and other neurodegenerative conditions and the potential benefit of compounds that modulate COX-2 and other inflammatory cytokines. The final section addresses nutritional modulation of inflammation and the chemopreventive value of anti-inflammatory nutraceutical agents. "

With the growing global fear of a major pandemic, avian influenza (AI) virus research has greatly increased in importance. In Avian Influenza Virus, an expert team of researchers and diagnosticians examine the fundamental, yet essential, virological methods for AI virus research and diagnostics as well as some of the newest molecular procedures currently used for basic and applied research. They present exciting, cutting-edge new methods that focus both on studying the virus itself and on work with avian hosts, an area greatly lacking in research.

In this new volume of the globally recognized Forensic Pathology Reviews, Dr. Michael Tsokos has gathered chapters from the top experts in the field to reveal both the applied and scientific areas of expertise along the broad spectrum of forensics studies. Volume 5 piques the mind as leading forensic pathologists from the United States and around the world offer advanced insight into death caused environmental conditions, trauma, neuropathology, natural causes, and ballistics. The authors of this volume further their exploration as they impart research related to identification, serial murder, histopathology, and age estimation. While unveiling unsurpassed and cutting-edge knowledge, Forensic Pathology Reviews, Volume 5 will also inspire emerging forensic scientists to immerse themselves in innovative research.

In recent years, a series of excellent textbooks have been published dealing with pathology of the thyroid gland. The present volume of CURRENT TOPICS IN PATHOLOGY provides further information for both pathologists and clinicians interested in the thyroid gland. The contributions deal with surgical pathology of the thyroid as well as with basic aspects of thyroid metabolism, hormone transport, and growth factors in thyroid cells. The topics covered in this book should mainly be considered as adjuncts to common textbooks on thyroid pathology. The contributions should help pathologists in their routine diagnosis and should stimulate further thyroid research.

Definition of the barrier The interstitial fluid (rSF) of the brain is separated from the blood by the blood-brain barrier (BBB). This barrier must not be thought of as a single entity or as an absolute restriction to all molecules, but as a multiple structure located at several sites within the brain. The first of these interfaces is located at the endothelium of the brain capillaries. Secondly there is a potential site for interchange on the outer linings of the brain between the dura and the arachnoid membranes. Thirdly, there are the choroid plexuses and the cerebrospinal fluid (CSF) which is in contact with the very permeable internal ependymal lining of the brain (Figure 1. 1). Finally there are areas of the brain which lack a blood-brain barrier. These areas constitute the circumventricu lar organs and have leaky capillaries with a barrier at the ependyma which limits the spread of molecules from those regions (Figure 1. 2). Each of these BBB sites has its own characteristic permeability and transport functions. We will now consider the properties of each of these barrier sites between the blood and the brain. THE CEREBRAL CAPILLARY ENDOTHELIUM Morphology This interface has both the largest surface area and the shortest path length between the blood and the brain rSF. The cerebral capillaries, which at first sight seem little different from the rest of the systemic circulation, are in fact unique to the brain."

Seymour Glagov The last meeting, devoted exclusively to an examination of the atherosclerotic plaque, took place in Chicago 25 years ago under the joint auspices of the Council on Arteriosclerosis of the American Heart Association and the Chicago Heart Association. The proceedings were published subsequently in a volume entitled "Evolution of the Atherosclerotic Plaque", edited by Richard J. Jones (1). Both experimental and human lesions were considered and several provocative new approaches to the disorder were discussed. The electron microscope was being applied systematically to the study of blood vessels at that time, so that details of the infrastructure and cellular composition of the artery wall and of atherosclerotic lesions were presented in some detail. There was, as one result of these explorations, considerable discussion of morphologic evidence suggesting that the principal cell involved in the atherogenic process was neither the fibroblast nor the macrophage, as had been supposed, but the smooth muscle cell. In particular, the findings indicated that this cell could incorporate lipid and become a foam cell.
