>I think you are probably on the right track with respect to a T cell
malignancy, which should be clonal by molecular techniques. Is the CD4
COEXPRESSED with the CD8? In either case, I would be curious to know if CD1,
CD2 and TdT were present.What about cytoplasmic TCR? Obviously, if DNA
aneuploid you could better make the call of malignancy w/out
clonal-molecular studies.
