This classification is based primarily on the microscopic characteris tics of tumours and therefore is concerned with morphologically identifiable cell types and histological patterns as seen with conven tional light microscopy. The term tumour is used synonymously with neoplasm. The phrase tumour-like is applied to lesions that clinically or morpholog ically resemble neoplasms but do not behave biologically in a neo plastic manner. They are included in this publication because they give rise to problems in differential diagnosis and because of the un clear distinction between neoplasms and...

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...

The 1973 WHO classification of bladder tumours anticipated a probable need for eventual revision of the criteria for diagnosing papillary and flat bladder neoplasia. A workshop sponsored by the WHO consisting of pathologists, urologists, cytologists, oncologists and basic scientists interested in bladder tumours addressed this subject, and after a follow- -up meeting sponsored by the International Society of Urological Pathology, the classification and terminology used in this text were agreed upon. A major change is in the introduction of a new category: papillary urothelial neoplasm of low...

During the past decade there has been an increasing awareness of the need for a different approach to the problem of bilharziasis. We do know that 180-200 million people are infected and that the infection is increasing but we have not as yet been able to answer the question: Are they suffering from a disease. Study of vital statistics or hospital records, mass biochemical or immunological tests and community surveys have not yet provided the full answer. Gradually and perhaps begrudgingly, we have come to realize that we must study the ma- initially by means of well controlled clinical...
