[The World Health Organization classification of lymphoid neoplasms]

The European Society of Pathology and the Society for Hematopathology have developed a new World Health Organization (WHO) classification of hematological malignancies. The classification is based on the principle that the classification is a list of entities defined by the combination of morphology, immunophenotype, genetic and clinical features. The WHO classification is a new basis of communications between pathologist and oncologist which will help to understand and treat hematological malignancies
