Blast crisis as the first presentation of chronic myeloid leukemia (CML) accounts for 10.0% of all cases. Objective: We report a case of megakaryocytic blast crisis as the first presentation of CML.

These disorders are termed acute megakaryocytic leukemia (AMKL) and transient abnormal myelopoiesis (TAM). The characteristics of blasts in these disorders have been extensively investigated from various standpoints including cytochemistry, cytogenetics, ultrastructure and in vitro-colony differentiation.

A low number of well‐differentiated but dysplastic megakaryocytes also were observed in lymph node and bone marrow smears. Acute megakaryoblastic leukemia (AMKL) is a rare malignancy affecting megakaryocytes, platelet-producing cells that reside in the bone marrow.

Per World Health Organization (WHO) criteria, establishment of megakaryocytic lineage requires expression of at least one platelet glycoprotein: CD41 (glycoprotein IIb/IIIa), CD61 (glycoprotein IIIa), or CD42 (glycoprotein Ib). 4 However, to date, no study has sought to characterize the relative performance of these markers in identifying blasts of megakaryocytic lineage.

It is classified as M7 according to the FAB system. AMKL is defined 21 Sep 2020 Acute myelomonocytic leukemia (AMML) · Criteria for diagnosis: myeloblasts, monoblasts and promonocytes are 20% or more of nonerythroid Juvenile myelomonocytic leukemia (JMML), Authors: Jay L. Hess. Abstract, Review on juvenile myelomonocytic leukemia, with data on clinics, pathology, and dispersed erythroid elements, and decreased numbers of megakaryocytes . I read with great interest the article by Wiseman et al1 regarding hemophagocytosis by leukemic megakaryoblasts in acute megakaryoblastic leukemia.

The neoplastic cells expressed the megakaryocytic markers factor VIII-related antigen and platelet glycoprotein-IIIa (CD61), and showed ultrastructural features that were indicative of megakaryocytic differentiation. Acute megakaryocytic leukemia (AmegL) corresponds to 5.0-10.0% of all acute myeloid leukemias (AML). Blast crisis as the first presentation of chronic myeloid leukemia (CML) accounts for 10.0% of all cases. Objective: We report a case of megakaryocytic blast crisis as the first presentation of CML. Patients with chronic myeloid leukemia (CML) infrequently present in blast crisis (BC). While most BC are of myeloid origin, megakaryocytic BC is rare, especially at the time of CML diagnosis.

Megakaryocytic leukemia pathology outlines

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. Acute megakaryoblastic leukemia (AMKL) is a rare malignancy affecting megakaryocytes, platelet-producing cells that reside in the bone marrow.

Acute erythroid leukemia (AML-M6) A neoplastic proliferation of immature cells (undifferentiated or proerythroblastic in appearance) committed exclusively to the erythroid lineage (> 80% of the bone marrow cells are erythroid, with ≥ 30% proerythroblasts), with no evidence of a significant myeloblastic component ( Swerdlow: WHO Classification of Tumours of Haematopoietic and Lymphoid Tissues, 4th Edition, 2017 )

Using the megakaryocytic leukemia cell lines, K-562 and CMK established from a Down's patient with acute megakaryoblastic leukemia, we studied the changes of antigen expression, cytosolic Ca2+ mobilization, thromboxane (TX) A2 formation and gene expression during megakaryocyte differentiation.

Associated with marrow fibrosis due to megakaryoblast secretion of fibrogenic cytokines, Acute Megakaryoblastic Leukemia (AMKL) is a subtype of acute myeloid leukemia triggered by megakaryocytes. 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 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. The SRF transcription factor and its cofactor, megakaryocytic acute leukemia (MKL1, also known as MAL or myocardin-related transcription factor-A, MRTF-A), control a large number of genes involved in growth factor response, cytoskeletal remodeling (e.g., vinculin, actin, and actin binding proteins), and muscle-specific functions such as myoblast fusion and differentiation. 159 The MKL1/SRF pathway is highly sensitive to changes in actin dynamics. 160 MKL1 is normally sequestered in the 2001-03-15 · Criteria for diagnosis of acute megakaryocytic leukemia. Strauchen JA. Comment on Blood.

The megakaryocytic nature of the leukemia has to be proven by ultrastructural demonstration of platelet peroxidase or by immunological demonstration of CD61, CD42, CD41 on the surface of the leukemic blasts.

Out of 34 cases of CML-Blast Phase between April 2015 and June 2016, 3 cases showed megakaryocytic differentiation. 2 of these presented in Blast phase as the first manifestation of CML and the third case was a known case of CML-Chronic phase. In this study, we aimed to generate a recombinant adenovirus serotype 5 (rAd5) vector that has a high efficiency in gene transfer to megakaryocytic leukemic cells with anticancer potential. We first modified the rAd5 backbone vector with a chimeric fiber gene of Ad5 and Ad11p (rAd5F11p) to increase the gene delivery efficiency.
