Rahman K, et al. - In this study, flow cytometric immunophenotyping (FCI) features were compared for the diagnosis of acute promyelocytic leukemia (APL) and non-APL acute myeloid leukemia (AML) cases which morphologically mimicked an APL. Researchers recognized FCI as a rapid and reliable modality for the diagnosis of an APL. An APL case was rapidly and specifically identified with the triple-negative profile (CD34-/HLA-DR-/CD11b-).
