Leroy Satchel Paige was the longtime Negro League star who eventually received his due in the majors. He reportedly got his nickname working as a baggage porter in Mobile, Ala., where he became a satchel tree by carrying several bags at once. Satchel, the man, was literally ageless.
The diagnosis of AML requires the identification of 20% or more leukemic blasts in the bone marrow. Further analysis then must separate AML from acute lymphoblastic leukemia by showing evidence for commitment to the myeloid lineage.
Most signs and symptoms of AML are caused by the replacement of normal blood cells with leukemic cells. A lack of normal white blood cell production makes the patient susceptible to infections; while the leukemic cells themselves are derived from white blood cell precursors, they have no infection-fighting capacity.arrow or blood is examined under light microscopy, as well as flow cytometry, to diagnose the presence of leukemia, to differentiate AML from other types of leukemia (e.g. acute lymphoblastic leukemia-ALL), and to classify the subtype of disease.
