Although immunophenotypic abnormalities have been reported in B-cell non- Hodgkin's lymphomas (NHLs) occurring in the general population, there are no extensive studies on such abnormalities in AIDS-related B-cell NHLs. Reactivity of CD45RO/UCHL1 and expression of other T-cell associated antigens (CD43, OPD4, CD3, CD5, EMA) were examined by immunohistochemistry in 66 diffuse aggressive AIDS-related B-cell NHLs and in 296 AIDS-unrelated B-cell NHLs of similar morphology analyzed in the same institution. EBER in situ hybridization studies were also carried out in 57 of the 66 AIDS-related B- cell NHLs investigated. CD45RO/UCHL1 was expressed in 27% of AIDS-related B- cell NHLs, but only in 8% of diffuse aggressive AIDS-unrelated B-cell NHLs. The difference was highly significant (P
