What it is

A rare, acute myeloid leukemia characterized by evidence of granulocytic maturation and more than 20% of blast cells in the bone marrow and/or peripheral blood.

Various degrees of anemia, thrombocytopenia, or pancytopenia are present. Frequent clinical manifestations include fatigue, fever, bleeding disorders, and organomegaly, especially hepatosplenomegaly.
