Since the first edition of Histological Typing of Tumours of the Eye and Its Adnexa, published in 1980, immunohistochemistry and find ings in molecular biology have contributed to our knowledge of the histogenesis of many tumours. These findings have been incorporat ed in this current text. The classification has been confined largely to true neoplasms. Tumour-like lesions (e.g. reactive lymphoid hyper plasia, pterygium, telangiectasia) are grouped with the benign tumours. Changes in nomenclature reflect an update in knowledge of morphological identification of cell types, behavioural...

This classification is based primarily on the presence of morpho logically identifiable cell types and growth patterns that can be correlated with the clinical behaviour of the tumour and, in some cases, with tumour markers in the serum. Although some of the histological terms and definitions have histogenetic impli cations, this classification is not meant to be histogenetic. The terminology adopted for individual tumours is based on their general acceptance and world-wide usage. Synonyms are includ ed only if they have been widely used in the literature or if they are considered helpful in...

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...

This is a classification of tumours and tumour-like lesions of the liver. It is based primarily on the microscopic characteristics of the tumours, and is therefore concerned with morphologically identi fiable cell types and histological patterns. The haematoxylin- and eosin-stained section remains the mainstay of morphological diag nosis, but special histochemical stains are often helpful and have been referred to in the explanatory notes. Readers interested in specific special stains mentioned in the text should consult Labora tory Methods in Histotechnology of the Armed Forces Institute of...
