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 (17.4%)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.
