American Journal of Clinical Pathology, 2009 Myeloid sarcoma (MS), also termed extramedullary acute myeloid leukemia, extramedullary myeloid tumor, and granulocytic sarcoma or chloroma, is a rare manifestation that is characterized by the occurrence of 1 or more tumor myeloid masses occurring at an extramedullary site.

Myeloid sarcoma as a manifestation of acute myeloid leukemia
Baylor University Medical Center Proceedings, 2021 We report a case of a 43-year-old man who presented with dyspnea because of large bilateral pleural effusions and imaging findings of a large periaortic mass with compression of the esophagus and left atrium. Subsequent soft tissue biopsy was consistent with myeloid sarcoma, and bone marrow biopsy was consistent with acute myeloid leukemia.

Ontogeny of Myeloid Cells [PDF]
Frontiers in Immunology, 2014 Granulocytes, monocytes, macrophages, and dendritic cells (DCs) represent a subgroup of leukocytes, collectively called myeloid cells. During the embryonic development of mammalians, myelopoiesis occurs in a stepwise fashion that begins in the yolk sac and ends up in the bone marrow (BM).

Myeloid Derived Suppressor Cells in Chronic Myeloid Leukemia [PDF]
Frontiers in Oncology, 2015 The suppression of the immune system creates a permissive environment for development and progression of cancer. One population of immunosuppressive cells that have become the focus of intense study is myeloid derived suppressor cells (MDSCs), immature myeloid cells able to induce immune-escape, angiogenesis, and tumor progression.

Myeloid sarcoma in the tongue [PDF]
Autopsy and Case Reports, 2020 Leukemic cells are rarely present in the oral cavity, and there are very few reports regarding such cases. However, we identified some reports of leukemic cells infiltrating tissues in the oral cavity, including gingival involvement. Recurrent painful oral ulcerations and prominent generalized periodontal destruction are the most common oral features ...

Cutaneous myeloid sarcoma associated with chronic myeloid leukemia [PDF]
Anais Brasileiros de Dermatologia, 2017 Myeloid sarcoma is an extramedullary tumor of malignant myeloid cells often associated with acute myeloid leukemia, chronic myeloproliferative disorders and myelodysplastic syndromes. The skin is one of the most commonly affected sites. We report a rare case of cutaneous myeloid sarcoma associated with chronic myeloid leukemia.

EZH2 in Myeloid Malignancies [PDF]
Cells, 2020 Our understanding of the significance of epigenetic dysregulation in the pathogenesis of myeloid malignancies has greatly advanced in the past decade. Enhancer of Zeste Homolog 2 (EZH2) is the catalytic core component of the Polycomb Repressive Complex 2 (PRC2), which is responsible for gene silencing through trimethylation of H3K27. EZH2 dysregulation

Myeloid malignancies and the microenvironment [PDF]
Blood, 2017 Abstract Research in the last few years has revealed a sophisticated interaction network between multiple bone marrow cells that regulate different hematopoietic stem cell (HSC) properties such as proliferation, differentiation, localization, and self-renewal during homeostasis.

Myeloid Cells and Lymphangiogenesis [PDF]
Cold Spring Harbor Perspectives in Medicine, 2012 The lymphatic vascular system and the hematopoietic system are intimately connected in ontogeny and in physiology. During embryonic development, mammalian species derive a first lymphatic vascular plexus from the previously formed anterior cardinal vein, whereas birds and amphibians have a lymphatic vascular system of dual origin, composed of lymphatic

Pediatric chronic myeloid leukemia in myeloid blast crisis
Autopsy Case Reports, 2023 Chronic myeloid leukemia (CML) accounts for 2-3% of childhood leukemias. About 5% of cases present in a blastic phase of CML which clinically and morphologically mimics more common acute leukemias of childhood. We report a case of a 3-year-old male who presented with gradual onset swelling of the abdomen and extremities along with generalized weakness.
