leukemia in which the involved cell shows little or no differentiation, usually consisting of blast cells; two types are distinguished, acute lymphocytic and acute myelogenous leukemia.
A rapidly progressing cancer of the blood-forming tissue (bone marrow).
A clonal (malignant) hematopoietic disorder affecting the bone marrow and the peripheral blood. The malignant cells show minimal differentiation and are called blasts, either myeloid blasts (myeloblasts) or lymphoid blasts (lymphoblasts). According to the type of blasts present, acute leukemias are classified as acute myeloid leukemia (AML) and precursor lymphoblastic or acute lymphoblastic leukemia (ALL).
A leukemia originating from a precursor bone marrow cell which is in an earlier developmental stage compared to lymphoblasts and myeloblasts. -- 2003
