There exists considerable overlap between the erythroid and megakaryocytic lineage at the gene as well as the protein level, both during normal development and in leukemic disorders.231-233'236'237'444'445 In terms of their immunophenotypic diagnosis, the lack of MPO expression by blast cells is the first indication of acute erythroid (AEL) or acute megakaryocytic leukemia (AMegL). Immunophenotyping reveals megakaryoblast expression of one or more platelet glycoproteins: CD41 (glycoprotein IIb/IIIa) and/or CD61 (glycoprotein IIIa).

Cytoplasmic pseudopods similar to those in megakaryocytic leukemia (M7) may be present. AMKL is a subtype of AML characterized by abnormal megakaryoblasts that express platelet-specific surface glycoprotein. Bone marrow biopsy frequently demonstrates extensive myelofibrosis, often making aspiration in these patients difficult. 2015-11-01 We present 15 patients with megakaryocytic (Mk) blast crisis (BC) of a Philadelphia (Ph) chromosome po-sitive CML confirmed by immunophenotype analysis between 1989-2000. 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.

It represents from 3 to 5% of AML cases, is frequently associated to myelofibrosis and is a subtype with poor prognosis. Acute myeloid (myelogenous) leukemia (AML) treatment options include chemotherapy, radiation therapy, stem cell transplant, and other medications.
