Острый миеломоноцитарный лейкоз
Определение
A rare acute myeloid leukemia disorder characterized by increased blast cells (myeloblasts, monoblast, and/or promonoblasts), representing more than 2% of the total bone marrow (BM) or peripheral blood differential counts, with 2-8% of BM cells being of monocytic lineage. Clinical presentation is the result of bone marrow involvement and extramedullary infiltration by the leukemic cells and includes asthenia, pallor, fever, dizziness, respiratory symptoms, easy bruising, bleeding disorders, and neurological deficits. Gingival hyperplasia, organomegaly, especially hepatosplenomegaly, and lymphadenopathy may also be associated.
