Although the purpose and scope of this monograph remain unchanged, I have been obliged to revise and rewrite many sections to keep pace with the recent growth in knowledge of endometrial pathology and physiology. New knowledge emanates from every quarter, engendered by improved meth ods of study in virtually every subspecialty, by exemplary cooperation between disciplines, and especially by the exchange of ideas internationally. On the other hand, the catalogue of diseases is everchanging. Some, once common, become rare or even disappear. Others suddenly appear, unique and previously unknown. Increased longevity, modern ways of living and new methods of treat ment have modified or augmented the clinical and diagnostic problems confront ing us. Accordingly, therapy with hormones and intrauterine contraception re ceive special attention, commensurate with the importance afforded them today. Under the precept "nil nocere," the almost unlimited uses for these agents warrant that their effects be carefully monitored by precise morphological stud ies, a prerequisite that succeeds only when clinician and pathologist cooperate closely. The sections on procedures for obtaining endometrial tissue, on steroid receptors, on functional disturbances, and on spontaneous abortion have been changed or expanded to incorporate new facts from recent discoveries that now appear significant. Only time, however, will prove their true value. Much of historical interest in the text has been left intact, for "who wants to read into the future, must consult the past" (Andre Malraux).

The great advances in knowledge of endometrial physiology and pathology made since the first edition of this monograph have compelled me to revise it. Although I have maintained the general plan in this second edition, many sections, especially those dealing with endometrial tumors and with endometrial changes caused by hormonal treatment, contraceptive agents and devices have been in large part rewritten. The sections on procedures for obtaining endometrial tissue, on functional disturbances and spontaneous abortion have been changed or expanded to incorporate new facts from recent discoveries that now appear to be significant. Only time, however, will prove their true value. All chapters have been scrutinized to insure they comprise only precise and up-to-date information. To complement the revisions and to replace previous illustrations 36 new photographs have been added. In accordance with all these improvements, the bibliography has been amended, with pertinent new references included and those deemed obsolete omitted. The author acknowledges with gratitude the help from thoughtful correspon dents who have suggested valuable changes or brought to her attention omissions or errors that inadvertently appeared in the first edition. Every effort has been made to rectify such mistakes. Again, the Springer Verlag has earned my hearty thanks for their patience and proficiency in preparing this new edition.

The 1st Edition of Histopathology of Non-Hodgkin's Lymphomas, written in col laboration with Professor H. STEIN and published in 1981, was received well and is now out of print. In the meantime, there has been an explosion of data that not only have made the definitions of various entities more precise but, above all, have confirmed the main entities originally delineated in the Kiel classification. The development of monoclonal antibodies and molecular cytogenetics has also made it possible to identify T-cell lymphomas more accurately. For example, many of the malignant lymphomas that were previously considered to be unclas sifiable can now be included in a classification scheme that places the T-cell lymphomas alongside of the list of B-cell lymphomas. In 1988 the European Lymphoma Club published an "updated Kiel classification" (STANSFELD et al. 1988) based on this new knowledge. It includes a number of previously undefined types of T-cell lymphoma. Studies done in Japan (T. SUCH! et al.) and China (L. Y Tu) have contributed to the understanding of these lymphoma types.

A comprehensive description of macroscopic, microscopic, and radiological methods for the diagnosis of bone diseases. The book presents all the procedures involved in diagnosis, using not only radiological and histological techniques, but also modern immunohistochemical and scintigraphic methods. Succinct and well-structured therapeutic recommendations are provided for an array of bone diseases, making this a practice-oriented reference work for pathologists, radiologists, rheumatologists, and orthopedists.
