Because neither morphologic nor routine cytochemical features are pathognomonic, the diagnosis of acute megakaryoblastic leukemia (AML-M7) is difficult, requiring either specialized ultrastructural or immunologic techniques. Because the ultrastructural techniques are cumbersome, immunologic assays for expression of several platelet-specific antigens, such as CD41a (platelet glycoprotein IIb/III...
Acute megakaryoblastic leukemia (M7 AML) is a highly aggressive disease. We evaluated outcomes in 57 children (11 with Down syndrome) and 69 adults with M7 AML after first complete remission (CR1) following autologous or HLA-identical allogeneic transplantation. Characteristics of the recipients of autologous transplants (38 children, 37 adults) were, respectively: median age, 1.7 and 46 years;...
The association between Down’s syndrome (DS) and acute leukemia is well documented. However, most information derives from retrospectively compiled patient series or treatment trials, which may not represent the general DS population. We report cases of acute leukemia and DS collected in the UK Childhood Cancer Study (UKCCS), a national population based case-control study. Data were gathered on...
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...

We report an 18-months old boy with trisomy 21 who initially presented with myelodysplastic syndrome MDS, and later transformed into acute megakaryoblastic leukaemia AML. At presentation he was found to have some unusual findings namely multiple soft tissue masses over scalp, left elbow and over the knee joints as well as hard mass felt in left hip. Biopsy of soft tissue of scalp revealed granu...
Acute myeloid leukemia (AML) is also referred to non-lymphocytic leukemia in the literature. It comprises about 15% of the childhood leukemia. There are multiple subtypes of AML from M0-M7 with approximately 45% of the cases being M0-M2 and the remaining subtypes being rare. The definitive diagnosis relies on bone marrow biopsy showing bone marrow infiltration with leukemic cells. We describe a...
Disease alleles that activate signal transduction are common in myeloid malignancies; however, there are additional unidentified mutations that contribute to myeloid transformation. Based on the recent identification of TET2 mutations, we evaluated the mutational status of TET1, TET2, and TET3 in myeloproliferative neoplasms (MPNs), chronic myelomonocytic leukemia (CMML), and acute myeloid leuk...
Somatic mutations in JAK2 are frequently found in myeloproliferative diseases, and gain-of-function JAK3 alleles have been identified in M7 acute myeloid leukemia (AML), but a role for JAK1 in AML has not been described. We screened the entire coding region of JAK1 by total exonic resequencing of bone marrow DNA samples from 94 patients with de novo AML. We identified 2 novel somatic mutations ...
The treatment of acute myeloid leukemia (AML) in children with Down's syndrome (DS) has engendered considerable controversy. Because of the concerns for toxicity and increased rate of infections, treatment approaches varied considerably in the past with mixed results. However, experience on the recently completed Pediatric Oncology Group (POG) 8498 AMI. study suggests that DS children with AML ...
