In recent years , there are increasing articles concerning Epstein-Barr virus associated lymphoproliferative disorder (EBV+LPD), and the name of EBV +LPD is used widely.However,the meaning of EBV+LPD used is not the same , which triggered confusion of the understanding and obstacles of the communication.In order to solve this problem.Literature was reviewed with combination of our cases to clarify the concept of EBV +LPD and to expound our understanding about it .In general, it is currently accepted that EBV +LPD refers to a spectrum of lymphoid tissue diseases with EBV infection , including hyperplasia , borderline lesions , and neoplastic diseases .According to this concept , EBV+LPD should not include infectious mononucleosis ( IM ) and severe acute EBV infection ( EBV +hemophagocytic lymphohistiocytosis, fatal IM, fulminant IM, fulminant T-cell LPD), and should not include the explicitly named EBV+lymphomas ( such as extranodal NK/T cell lymphoma , aggressive NK cell leukemia , Burkitt lymphoma, and Hodgkin lymphoma , etc.) either.EBV +LPD should currently include: ( 1 ) EBV +B cell-LPD:lymphomatoid granulomatosis , EBV +immunodeficiency related LPD , chronic active EBV infection-B cell type, senile EBV +LPD, etc.(2) EBV +T/NK cell-LPD:CAEBV-T/NK cell type, hydroa vacciniforme, hypersensitivity of mosquito bite, etc.In addition, EBV+LPD is classified, based on the disease process , pathological and molecular data , as 3 grades:grade1, hyperplasia ( polymorphic lesions with polyclonal cells ); grade 2, borderline ( polymorphic lesions with clonality ); grade 3, neoplasm (monomorphic lesions with clonality).There are overlaps between EBV +LPD and typical hyperplasia, as well as EBV+LPD and typical lymphomas .However , the most important tasks are clinical vigilance , early identification of potential severe complications , and treating the patients in a timely manner to avoid serious complications , as well as the active treatment to save lives when the complications happened .
