Abstract:
Objective To study the clinical, pathologic, immunophenotype, molecular characteristics and prognosis of HIV-negative plasmablastic lymphoma ( PBL ).Methods Twelve cases of HIV-negative PBLs diagnosed between 2005 and 2014 in Guangdong General Hospital were identified according to WHO classification of tumors of haematopoietic and lymphoid tissues ( 2008 ) .The clinicopathologic features and outcome were analyzed and the relevant literatures were reviewed .Results The patients were predominantly male (11/12) with a median age of 55.5 years.The tumor cells showed the characteristic combination of immunoblastic/plasmablastic morphology , plasma cell phenotype and high proliferation, no expression of mature B cell markers.7/10 of the cases were EBER positive.Two cases were positive for C-myc translocation.Four of twelve patients were died.Conclusions PBL is a rare, aggressive B-cell lymphoma.HIV-negative PBL has lower rate of oral involvement and EBER expression than HIV -positive patients ,the differential diagnosis is very challenging ,and the prognosis is worse.
