Histological Typing Of Endocrine Tumours

This second edition updates the "WHO Classification of Endocrine Tumours" proposed in 1980 and incorporates many new tumour entities and pertinent concepts that have developed since that time. It is the result of a collaborative effort between 9 pathologists from different countries, in addition to informal contributions and discussions by many other colleagues. In particular, efforts have been made to integrate into the fundamental backbone of the histologic classification a number of prognostic and functional parameters now essential for appropriate diagnosis and clinicopathologic evaluation of endocrine tumours.

This classification represents a project aimed at bringing together the variety of ways thymic epithelial neoplasms have been classified. It focuses on their growth characteristics, and cytoarchitectural features . The classification, though restricted to the thymic region rather than the mediastinum in general, also covers neuroendocrine, germ cell, lymphoid, and stromal tumours, as well as tumour-like lesions and the neck tumours of thymic or related branchial pouch derivation.

The WHO Classification of Tumours of Endocrine Organs is the 10th volume in the 4th Edition of the WHO series on histological and genetic typing of human tumours. This authoritative, concise reference provides an international standard for oncologists and pathologists and will serve as an indispensable guide for use in the design of studies evaluating response to therapy and clinical outcome. Diagnostic criteria, pathological features, and associated genetic alterations are described in a disease-oriented manner. Sections on all recognized neoplasms and their variants include new ICD-O codes, epidemiology, clinical features, pathology, genetics, prognosis, and predictive factors. The book, prepared by 166 authors from 25 countries, contains more than 700 color images and tables and more than 3100 references.

This is the revised edition of the WHO histological classification of oesophageal and gastric tumours. It reflects the important changes that haveoccurred since the first edition in the fields of lymphomas, endocrine tumours and the dysplasias as well as adding a number of newly describedentities. it sets the international standard for the next decade.

Although the histological typing of ovarian tumours is the focus of this volume, other aspects of investigation of a specimen of ovarian tumour are also important. Some of these aspects are mentioned in the text or illustrated. They include tumour grading, which is impor­ tantprognostically and therapeutically for certain types ofovarian tu­ mour, quantification ofcomponents in mixed tumours and evaluation of the stroma of certain tumours that are associated with endocrine function. Grading methodologies have varied from one tumour type to another and from one group of investigators to another for the same type of tumour. Because a standard internationally recognized grading methodology has not been established, no specific guidance is presented in this volume. Nevertheless, grading by any generally acceptable method should be incorporated in the diagnosis whenever appropriate. The clinical and pathological classification of the extent of tu­ mour growth (staging) should be taken into account for the purposes of treatment and prognosis. The TNlV1/FIGO system is therefore in­ cluded (p. 45).

Neuroendocrine neoplasms comprise a large family of proliferative lesions that involve almost every part of the body. Our understanding of their cells of origin as well as the pathology, pathophysiology and genetics of these neoplasms has made tremendous advances in the last few decades. While they are often discussed as separate entities in textbooks of gastroenteropancreatic pathology and pulmonary pathology, their scope is much broader. The book conveys the similarities and differences of these fascinating tumors that may be found from the hypothalamus and pituitary to the rectum, and in soft tissue as well as in many organs. Written by experts in the field, the authors emphasize their structural, functional, predictive and prognostic features and attempt to provide the clinical context that allows improved diagnosis and therapy while building on the genetics that clarifies patterns of inheritance and predisposition to tumor development through precursor lesions. The Spectrum of Neuroendocrine Neoplasia provides a broad overview of neuroendocrine neoplasms using a practical approach to diagnosis, histological classification and therapy, and presents the most important and significant developments of the technologies used to diagnose, classify and treat them.
