French-American-British (FAB) classification class M2

WHO Classification (2016 revision) is a separate entity under the “Acute myeloid leukemia (AML) and related neoplasms”

those with specific cytogenetic abnormalities (e.g. t(8;21) or inv(16))

those whose myeloblasts express T-cell surface markers, CD13, or CD14

those with high peripheral white blood cell counts
