THE DETECTION OF CD56 AND EPSTEIN-BARR VIRUS IN T-CELL LYMPHOMAS

Qingping Jiang, Hanliang Lin, Muheng Zhou

Abstract

Objective: To study the relationship between EBV infection and the expression of CD56 in T-cell lymphomas (TCLs).
Methods: 46 cases of TCLs and 15 cases of reactive hyperplasia of lymphonodes (RHs) were detected CD56 by immunohistochemistry and EBERs by in situ hybridization.
Results: 8 cases of 46 TCLs (17A%) showed CD56-positive. On sites, CD56 positive rate of nasopharyngeal TCLs was highest (5/17, 29.4%), and on subtypes, that of DLs was highest (6/16, 37.5%). Additionally, 4 RHs were also CD56-positive. Of 46 TCLs, 24 showed expression of EBERs. There were only 4 TCLs expressing both CD56 and EBERs.
Conclusion: The expression of CD56 was not especially for TCLs that EBV infected. EBV infection was not related with CD56- positive TCLs. The findings also suggested the expression of CD56 in TCLs be possibly related to original sites and subtypes of TCLs.
