Neonatal acute megakaryoblastic leukemia mimicking congenital neuroblastoma

Acute Megakaryoblastic Leukemia with t(1;22) Mimicking Neuroblastoma in an Infant

Acute megakaryoblastic leukemia (AMKL) with t(1;22) (p13;q13) is an extremely rare subtype of acute myeloid leukemia that is almost always described in infants. t(1;22) (p13;q13)-positive AMKL with extramedullary infiltration has been previously reported only once in the literature. Herein, we report a 3-month-old infant presenting with a pelvic mass and pancytopenia suggesting neuroblastoma. B...

Simultaneous Neuroblastoma and Acute Lymphoblastic Leukemia in an Infant

Alpha-Synuclein Expression in Acute Erythroleukaemia, Acute Megakaryoblastic Leukemia, and Normal Counterparts in Bone Marrow

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 dis...

Acute Myeloid Leukemia Mimicking as Acute Megakaryoblastic Leukemia

Down syndrome or constitutional trisomy 21 was linked to leukemia for the first time in a case report published in 1930 since then, down syndrome has been recognized as one of the most important leukemia – predisposing syndromes and patients with down syndrome and leukemia have unique clinical features and significant differences in treatment response toxicity profiles compared to patients with...

The proto-oncogene ERG in megakaryoblastic leukemias.

Aneuploidy is one of the hallmarks of cancer. Acquired additions of chromosome 21 are a common finding in leukemias, suggesting a contributory role to leukemogenesis. About 10% of patients with a germ line trisomy 21 (Down syndrome) are born with transient megakaryoblastic leukemia. We and others have shown acquired mutations in the X chromosome gene GATA1 in all these cases. The gene or genes ...
