Popis: The expression of T cell-associated antigens on B cell non-Hodgkin lymphoma is rare. We describe 5 cases of B-chronic lymphocytic leukemia (B-CLL) with aberrant expression of CD8 on B cells. These B-CLL presented a typical immunophenotype CD19+, CD23+, FMC7– and CD5+ (except for 1 case) with a monotypic expression of surface immunoglobulin light chain kappa. The CD8 expression was confirmed on B-CLL cells by two-color flow cytometry staining. We could not find coexpression of CD3 or CD4 on B-CLL cells. The clinical implications, the sensitivity to therapy and the prognostic outcome of this aberrant expression remains to be determined.
