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.

Recent Advances in Histopathology: 25 features a collection of in depth reviews of the latest developments in the field. Written in an accessible and easy to read format supplemented by a wealth of colour microphotographs, the book is authored by leading recognised experts. Much of Volume 25 focuses on COVID-19, describing its histopathologic manifestations in various organs and the mechanisms involved in the pathogenesis of the virosis. Other chapters discuss topics such as endocervical adenocarcinoma, cystic kidney tumours, and interstitial diseases of the lung. Each article provides a comprehensive overview, and emphasises the salient points of interest, with a ‘key clinical points for practice’ section concluding the chapter. This latest volume in the series is an invaluable resource for busy clinicians and those sitting FRCPath examinations.

Rubin and Damjanov's latest volume of Pathology Reviews highlights the latest progress in the interface of biology and disease. Forefront techniques and experimental models that were once considered exotic or esoteric, are explored here in the context of understanding more fully the processes involved in human disease. Topics include: regulation of liver growth * contractile cells in lungs * mineral formation in bone * folate metabolism * the "riddle of the mast cell" * HLA antigens * interleukin 6 * IgA nephropathy * Goodpasture syndrome * anti-basement membrane glomerulonephropathy * molecular mechanisms of oncogenesis * molecular diagnosis of cancer * inhibition of intercellular communication in carcinogenesis * DNA repair and its pathogenetic implications * human and rat mammary tumorigenesis. Pathology Reviews * 1990 is essential reading for everyone concerned with the mechanisms of disease.

Pathobiology of Human Germ Cell Neoplasia is a state-of-the-art compendium on a very recent branch of tumor biology. It offers an awareness and understanding of germ cell tumors: from the earliest stages to their va- rious differentiations. Original data for this volume was supplied by experts in the fields of pathology, developmental biology, genetics, molecular biology and other related fields. This compilation of knowledge provides information necessary to persons working in clinical and preclinical areas.

New methods in immunocytochemistry and hybridization techniques enable the pathologist active in diagnosis to clarify more effectively problems in the classification and prognosis of tumors. By adopting these methods into his diagnostic repertoire it will be possible to create a closer, more productive connection between morphological diagnosis and clinical work. This volume gives the reader an up-to-date general survey from international experts of the method, technique and practical application of these new procedures.

Rather, until The concept that human disease is a specialized branch of biology is universally accepted today, but in the mid-20th century, the accretion of individual historical perspective, is actually of recent origin.

This is the second edition of a practice-oriented, well-illustrated manual on the microscopic grading of tumors. After an introduction on the history and basic tenets of tumor grading, subsequent chapters focus on specific organ systems. In each case, the most widely used system for grading common tumors is presented and discussed. Throughout, careful attention is paid to the principles of microscopic tumor grading, ancillary methods to improve grading, and the latest techniques used in evaluating tumors and formulating prognosis. Since the first edition, all chapters have been updated to reflect revisions in the clinical practice of pathology and to explain the role of novel immunohistochemistry and molecular biology techniques. In addition, a new chapter is devoted to the latest trends in cancer grading, and further illustrations have been included. Cancer Grading Manual is a superb resource for both diagnostic surgical pathologists and pathology residents.

This book is a review of gynaecologic and breast pathology for clinicians and trainees. Divided into seven sections, topics are presented in question and answer format, covering both common and less common pathologies that may be encountered in female genital and reproductive organs and the breast. The final section of the book covers immunohistochemistry and cytogenetics of tumours in these organs. Questions and answers are both textual and visual, based on microphotographs illustrating key pathologic entities. Authored by recognised pathologists led by Prof Ivan Damjanov from University of Kansas School of Medicine, the text is enhanced by colour microphotographs and figures.
