![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=1720289234&Signature=O3xPZb-L0r23~7qxxx5NFUYYQBkTJ5j~AQq-5gnb2QSp2ZYYd0zzZavwX3~cEXlf-gO~jgK89tYBSqt6OLWvsSm~Op5l5Q5p6yYtD-KZ9bk8RzbN34S7i-lDXkvKiFC-7QDOX3n5u5Lz1~9qHJjS59VI~Yt8rf~rGxZXsZrQQCxx-5W13D2k-xNf-yY77l982k~JguUE~gpUh3y6sUlTq0uOEjOcpLQ8RIQi7G1D7PEqOgY1ey1XuN~zhXZyNiUcUvjnFp4u-Ljlt2tZ1WCqpnTll39gjKtOFvTd4sgwWUfbBm~hmOuFgXPhxNYEVEJGdQdexwD4xbG21FzZmPt8YQ__&Key-Pair-Id=APKAIE5G5CRDK6RD3PGA)
