This case suggested that chromosomal alterations may precede morphological, flow cytometric and clinical changes and accelerate progression of the disease. Acute myeloid leukemias (AMLs) are hematologic malignancies with varied molecular and immunophenotypic profiles, making them difficult to diagnose and classify. Sometimes, however, the cancer cells adapt to evade the therapy by not expressing anymore an antigen that they expressed earlier, which might have been targeted by a monoclonal antibody or other therapy, like CAR T-cells.
