Part of the World Health Organization book series (HISTOLOG.CLASS)


This classification is based primarily on the microscopic characteristics of tumours. It is therefore concerned with the identification of cell types and histological patterns as seen by conventional light microscopy. In general, time-honoured terms have been retained. Synonyms are listed only if they have been widely used or if they are considered to be important for understanding the disease process. In such cases, the preferred term is given first, followed by the synonym in parentheses.
