This updated reference has been prepared by the world's leaders in neoplastic hematopathology, a field that covers disorders of the bone marrow, spleen, and lymphatic system. This is the only comprehensive, encyclopedic text that covers the three major organ systems and integrates basic science, modern diagnostic techniques, and clinical aspects of malignant diseases affecting these organs. The Second Edition features several new contributors, more full-color illustrations, updated chapters, and three new chapters--Clinical Relevance of the Revised European/American Lymphoma Classification of Non-Hodgkin's Lymphomas; Normal Histology and Immunoarchitecture of the Lymphohematopoietic System; and Application of Molecular Genetics to the Diagnosis and Classification of Acute Leukemias.
