While it is true that CD43 is not lineage specific, I would disagree
that it is of limited diagnostic utility in all types of cases. As
with any antigen, you have to know the limitations of its detection
and CD43 is expressed by almost all types of acute leukemia as well as
T cell lymphomas and some B cell neoplasms. The coexpression of CD43
with CD20, however, can be quite helpful in the B-cell lymphocytic
lymphomas, and CD43 is included in the immunophenotype descriptions of
the REAL classification. I believe that CD43 is as useful, or more
useful, than many antigens commonly studied by flow cytometry for
these B cell neoplasms (such as CD11c). By convention, however, it
has never made its way into most flow cytometry panels for these
diseases.

CD43 is not lineage specific and therefore has limited diagnostic utility.
