Acute megakaryoblastic leukemia is a relatively rare form of acute leukemia that has heterogeneous blast morphology and karyotypic abnormalities. An 8-month-old boy with a retroperitoneal mass was diagnosed as having acute megakaryoblastic leukemia that initially presented as small round cell tumor of childhood. Bone marrow aspiration showed syncytial groups of atypical medium sized cells with scant cytoplasm and fine nuclear chromatin. Retroperitoneal mass biopsy showed several lymph nodes with cohesive clusters of neoplastic cells that demonstrated expression of Factor VIII. Flow cytometric analysis of the second bone marrow aspiration showed CD 61 positivity. Karyotypic analysis of bone marrow cells showed a novel translocation, (1;5)(q21;p13).

Identifying inflammation-induced leukocyte subsets and their derived circulating factors has been instrumental in understanding the progession of ALI/ARDS. Nevertheless, how primary inflammation-induced non-leukocyte populations in distal organs contribute to ALI/ARDS remains poorly defined. Here, we report one population of erythroblast-like cells (Ter-cells) deriving from megakaryocyte- erythroid progenitor cells with a unique Ter-119+CD45-CD71+ phenotype in ALI/ARDS.

Pediatric acute myeloid leukemia frequently harbor fusion oncogenes associated with poor prognosis, including KMT2A, NUP98 and GLIS2 rearrangements. While murine models have demonstrated their leukemogenic activities, the steps from a normal human cell to leukemic blasts remain unclear. Here, we precisely reproduced the inversion of chromosome 16 resulting in ETO2::GLIS2 fusion in human induced pluripotent stem cells (iPSC).

Article Synopsis
- Transient abnormal myelopoiesis (TAM) in neonates with Down syndrome (DS) presents similarly to acute megakaryoblastic leukemia but usually resolves on its own within months postpartum.
- Some cases of TAM can lead to severe health issues, impacting the patient's prognosis negatively.
- An autopsy of a stillborn female with TAM and DS revealed GATA1s protein expression in unusual immature megakaryocytes, indicating that placental tissue can be useful for diagnosing TAM histologically.
