Definition. Acute megakaryoblastic leukemia (AMKL) is one form of acute myelogenous leukemia (AML).It is classified as M7 according to the FAB system. AMKL is defined as an AML with >20% blasts, of which 50% or more are of the megakaryocyte lineage.

It is characterized by a proliferation of ≥20% megakaryoblasts identified by specific antigens using flow cytometry with associated extensive myelofibrosis of the bone marrow. 2020-11-27 2016-01-01 acute megakaryoblastic leukemia (acute megakaryocytic leukemia) a form of acute myelogenous leukemia in which megakaryocytes are predominant and platelets are increased in the blood, often with fibrosis; it can occur at any age. Called also megakaryoblastic or megakaryocytic leukemia. acute megakaryoblastic leukemia (acute megakaryocytic leukemia) a form of acute myelogenous leukemia in which megakaryocytes are predominant and platelets are increased in the blood, often with fibrosis; it can occur at any age. Called also megakaryoblastic or megakaryocytic leukemia. M7 leukemia is not infrequent in children younger than 3 years of age, especially in those with Down's syndrome.

(Eig, Pers, 1891 2009-02-19 2013-07-10 Background:Acute megakaryocytic leukemia (AMkL) in Down syndrome (DS) children is uniformly associated with somatic GATA1 mutations, which result in the synthesis of a shorter protein (GATA1s) with altered transactivation activity compared to the wild-type GATA1. Acute megakaryoblastic leukemia (AMKL) is life-threatening leukemia in which malignant megakaryoblasts proliferate abnormally and injure various tissues. Megakaryoblasts are the most immature precursor cells in a platelet -forming lineage; they mature to promegakaryocytes and, ultimately, megakaryocytes which cells shed membrane-enclosed particles, i.e. platelets, into the circulation.

As a result, acute megakaryoblastic leukemia (AMKL) is now accepted as a distinct category (M7) of acute myeloid leukemia for human beings, according to the classification proposed by the French-Ame rican-Brit­ ish Cooperative Group.' Cells of the megakaryocytic series reveal a variable periodic acid-Schiff reaction, a

This disease is defined as any malignancy that affects the body’s bone marrow and production of infection-fighting white blood cells—the cancerous cells multiply rapidly and crowd out the healthy cells in the bone marrow, which lowers a patient’s resistance and ability to fight off infection. The blast cells show one or more megakaryocytic markers (i.e. Factor VIII, CD61, CD41, or CD42), they test negative when using the anti-myeloperoxidase monoclonal antibody and never show coordinated expression of lymphoid markers, though isolated CD2 or CD7 positivity can be found on some occasions. Acute Megakaryocytic Leukemia AMKL is a subtype of AML characterized by abnormal megakaryoblasts that express platelet-specific surface glycoprotein.

Called also megakaryoblastic or megakaryocytic leukemia. Acute megakaryocytic leukemia was first described as a subtype of acute myelogenous leukemia (AML) in 1931 1 and was incorporated into the French-American-British (FAB) classification of AML as M7 in 1985. 2 Bone marrow characteristics include proliferation of abnormal megakaryoblasts identified by the presence of platelet-specific surface glycoprotein and frequently extensive myelofibrosis.
