background:alpha-synuclein is a member of synuclein family of proteins with unidentified function localized in the cytoplasm, mitochondria of neurons, and presynaptic nerve endings. although it is found in the lewy bodies in synucleinopathies and in alzheimer’s disease, the protein could also be considered as a novel marker in diagnosis of diseases related to the hematopoietic system. methods: ...

Acute megakaryoblastic leukemia(AML-M7) is a rare type of pediatric AML. It represents approximately 1% of all leukemias during childhood & has an incidence of 0.5% per million per year. In young children with Down syndrome, AML-M7 is the most common type of AML. There is no association reported till date in between Down syndrome & Haemoglobin E-Beta thalassaemia. In our case we got rare associ...

We report the nonrandom occurrence and frequency of the t(1;22)(p13;q13) in acute myeloid leukemia (AML) and its close association with the French-American-British M7 subtype of AML in infants (less than 1 year). This chromosomal abnormality occurred in 6 of 252 (2.4%) children and adolescents with AML (6 of 28 infants, 22%; 6 of 18 M7 AML cases overall, 33%; and 6 of 6 M7 cases in infants). In...

Although it is found in the Lewy bodies in synucleinopathies and in Alzheimer’s disease, the protein could also be considered as a novel marker in diagnosis of dis...

Acute megakaryocytic leukemia (AML M7) is a rare type of acute myelogenous leukemia in adults, commonly presenting with myelofibrosis. This report describes a case of a 32-yr-old male who presented with hypercalcemia and bony lytic lesions, in the absence of myelofibrosis. The diagnosis of AML M7 should be considered in a patient with pancytopenia, lytic lesions and hypercalcemia.

Acute megakaryocytic leukemia (M7-AML) is a rare form of acute myeloid leukemia (AML), which is associated with poor prognosis. The case presented in the current report is a statement for the difficult diagnosis and clinical management of M7-AML in the context of a previous hematologic disorder of undetermined significance and associated genetic abnormalities. Probably, following the complete h...

We report the findings from a patient who presented with a concurrent mediastinal germ cell tumor (GCT) and acute myeloid leukemia (AML). Bone marrow pathology was consistent with a diagnosis of acute megakaryoblastic leukemia (AML M7), and biopsy of an anterior mediastinal mass was consistent with a nonseminomatous GCT. Prior studies have described associations between hematological malignanci...

Thrombopoietin (TPO) is implicated as a primary regulator of megakaryopoiesis and thrombopoiesis. However, the biologic effects of TPO on human acute myeloblastic leukemia (AML) cells are largely unknown. To determine if recombinant human (rh) TPO has proliferation-supporting and differentiation-inducing activities in AML cells, 15 cases of AML cells that were exclusively composed of undifferen...

Acute myeloid leukemia (AML-M7) is a type of pediatric AML accounting for 3–10% of primary childhood AML and children may present with a broad variety of symptoms including low-grade fever, diarrhea, easy bruising, failure to gain weight and life-threatening conditions. We report a rare case of AML .A 26-month-old boy who presented with weakness and fatigue. He was diagnosed as a case of AMLM-7...
