  • Presence of t(8;21)(q22;q22) in myeloperoxidase-positive, myeloid surface antigen-negative acute myeloid leukemia AMERICAN JOURNAL OF CLINICAL PATHOLOGY Arber, D. A., Glackin, C., Lowe, G., Medeiros, L. J., Slovak, M. L. 1997; 107 (1): 68-73


    Although acute myeloid leukemias (AMLs) cytochemically negative for myeloperoxidase are now well recognized, myeloid surface antigen-negative AMLs are rare. The morphologic, cytochemical, immunologic, and cytogenetic or molecular features of such cases are described in four adults aged 19 to 60 years. All had AML with maturation (FAB M2) and were myeloperoxidase positive. Immunologic studies showed all to be HLA-DR positive but negative for the CD13, CD14, and CD33 antigens. Two of four were CD34 antigen positive. Cytogenetic studies were performed in three patients, and all demonstrated t(8;21)(q22;q22). In studies using the reverse transcriptase polymerase chain reaction in two patients, including the patient in whom karytypic analysis was not performed, the AML1-ETO fusion product of t(8;21) was identified. These findings suggest an association between the lack of myeloid antigen expression in myeloperoxidase-positive AML and the presence of t(8;21). In addition, the results demonstrate the continued need for cytochemical studies in the evaluation of acute leukemias.
