Acute myeloid leukemia (AML) is a group of diseases resulting from a clonal expansion of myeloid precursor cells in the bone marrow. Each subtype harbors characteristic clinical, morphologic, and molecular features. AML is most often de novo and arises from somatic mutations causing unchecked proliferation of myeloblasts, but it may also present as a secondary malignancy, often as the result of prior cytotoxic exposure. Here we present a case of therapy-related AML (t-AML) following chemotherapy exposure found to have a characteristic balanced translocation involving 11q23 and outline a potential mechanism of oncogenesis. |
