The clinical, hematologic, and histologic features ofacute megakaryoblastic leukemiaare described Acute megakaryocytic leukemia (AMegL) is a rare subtype of acute myeloid leukemia (AML) developing from primitive megakaryoblasts, first described by Von Boros and colleagues in 1931.1 The disease can be identified by antibodies to glycoprotein IIb/IIIa and is often associated with extensive myelofibrosis.2-9 Reports in the literature have been sporadic because of both the rarity of the 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. 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. The clinical, hematologic, and histologic features of acute megakaryoblastic leukemia are described for an 8-year-old female Domestic Shorthair cat, a 3-year-old female mixed-breed dog, and a 3-year-old male German Shepherd Dog. The neoplastic cells were characterized as belonging to the megakaryocytic lineage.

Blood smear evaluation and cytologic examination of lymph node and bone marrow aspirate specimens revealed a large population of poorly differentiated blast cells with morphologic features suggesting megakaryocytic lineage. A low number of well‐differentiated but dysplastic megakaryocytes also were observed in lymph node and bone marrow smears.

Megakaryoblasts (often better morphology on biopsy than smear) are medium / large cells with blue vacuolated, agranular, eosinophilic cytoplasm containing fine granules, cytoplasmic projections (blebs and pseudopods) resembling platelets, irregular cytoplasmic borders and cytoplasmic zoning; may occur in clusters Acute megakaryoblastic leukemia is divided into three groups, AMKL in children with Down syndrome (DS-AMKL), AMKL in children who do not have Down Syndrome (non-DS-AMKL), and AMKL in non-DS adults (AMKL adults).The basis of the diagnosis of AMKL or AML-M7, according to FAB, is the presence of megakaryocyte line cells as many as 30% or more of all cells. Acute megakaryocytic leukemia (AMegL) is a biologically heterogenous subtype of acute myeloid leukemia (AML) that arises from megakaryocytes. Improvements in the accuracy of diagnosing AMegL as well as interest in the molecular analysis of leukemias have led to an increased amount of data available on this rare AML subtype.
