Abstract

Since the publication of the Revised European-American Classification of mature lymphoid neoplasms in 1994, subsequent updates of the classification of mature lymphoid neoplasms have been generated through iterative international efforts to achieve broad consensus among hematopathologists, geneticists, molecular scientists, and clinicians. Significant progress in the characterization of malignancies of the immune system in the last years, with many new insights provided by genomic studies, have led to the current proposal. We have followed the same process that was successfully used for the 3rd and 4th editions of the WHO classification of hematological neoplasms. The definition, recommended studies, and criteria for the diagnosis of many entities have been extensively refined. Some categories considered provisional are now upgraded to definite entities. Terminology of some diseases has been revised to adapt nomenclature to the current knowledge of their biology, but these modifications have been restricted to well-justified situations. Major findings from recent genomic studies have impacted the conceptual framework and diagnostic criteria for many disease entities. These changes will have an impact on optimal clinical management. The conclusions of this work are summarized in this report as the proposed International Consensus Classification (ICC) of mature lymphoid, histiocytic, and dendritic cell tumors.
