![Immunophenotypic variation within AML with mutated NPM1. Myeloid and monocytic AML-NPM1 show distinct patterns of CD34 and HLA-DR expression. The most common blast phenotype in myeloid AML-NPM1 was a CD34−/HLA-DR− phenotype (69 [49%] of 141). In monocytic AML-NPM1, a majority of cases were negative for CD34 and positive for HLA-DR (80 [82%] of 98).](https://ash.silverchair-cdn.com/ash/content_public/journal/bloodadvances/3/21/10.1182_bloodadvances.2019000328/3/advancesadv2019000328f1.png?Expires=1736059559&Signature=VjKHNCQc2GCVhYDBzNh3ZZ~9WaCIneE1rCCmOIYbVWMWloX7OBGPQt7flziiN2~lHuOGZpfHJXvXQyNjg-C-4uFVDPCblgxKG1cjFjiB2cKOkqYJWCrtxrZP0OiDk-EBuW1jcbQT65omIRhIzWNc-GtuS6V0BMdZp4E00Nfb821EXvcyM59rPVsyNAApwRz8vjAHyefph0Sbo2FFjtZyzVpkPbXxmws1FQwAfHS5VXYOntdMsYwGYx0MJLsGkSsGAJqd-HqDv8mSmzMycttUDVw~9ssKTvdHRHVcSiATjv3dDwK8aLBN8Cn4Hj9IYPn72Ipnd3B10wh3ErfgWgBY8A__&Key-Pair-Id=APKAIE5G5CRDK6RD3PGA)
