| A subtype of acute myeloid leukemia with recurrent genetic abnormalities characterized by clonal proliferation of myeloid blasts in the bone marrow, blood and rarely other tissues. Bone marrow typically shows small hypo-lobated megakaryocytes and multilineage dysplasia. Patients typically present with leukocytosis, anemia, and variable platelet counts and a variety of nonspecific symptoms related to ineffective hematopoesis (fatigue, bleeding, bruising, recurrent infections, bone pain) and/or extramedullary site involvement (gingivitis, splenomegaly). High resistance to conventional chemotherapy is reported. |
