Granulocytic sarcoma (GS), myeloid sarcoma (MS) or extra medullary leukemic deposits is an unusual manifestation of AML, accounting for about 3% of acute leukaemia’s. GS may occur as a manifestation of a systemic myelogenic leukaemia or it may precede systemic manifestations of peripheral blood and bone marrow. When GS precedes the development of systemic leukemia the diagnosis can be difficult...

The case of a previously healthy 24-year-old man diagnosed with extradural thoracic granulocytic sarcoma with no evidence of bone marrow or other hematological involvement is described. The tumor was removed totally by microsurgery. The histopathological examination was consistent with granulocytic sarcoma. Granulocytic sarcomas are most commonly found in the context of an acute myelogenous leu...

CGS: cutaneous granulocytic sarcoma GS: granulocytic sarcoma IHC: immunohistochemistry KP: Koebner phenomenon MDS: myelodysplastic syndrome MPO: myeloperoxidase PG: pyoderma gangrenosum TGF-b1: transforming growth factor-beta 1 TGF-b1R: transforming growth factor-beta 1 receptor INTRODUCTION Granulocytic sarcoma (GS) is also known as myeloid sarcoma or chloroma because of its green hue caused b...

Extramedullary (EM) manifestations of acute leukemia include a wide variety of clinically significant phenomena that often pose therapeutic dilemmas. Myeloid sarcoma (MS) and leukemia cutis (LC) represent 2 well-known EM manifestations with a range of clinical presentations. MS (also known as granulocytic sarcoma or chloroma) is a rare EM tumor of immature myeloid cells. LC specifically refers ...

Myeloid sarcoma (chloroma, granulocytic sarcoma, or extramedullary myeloid tumour) is an extramedullary mass forming neoplasm composed of myeloid precursor cells. It is usually associated with myeloproliferative disorders but very rarely may precede the onset of leukemia. Here, we are presenting a rare case of primary vaginal myeloid sarcoma in a geriatric female patient without initial present...

leukemia. The cells were examined daily under the electron micro scope between the 5th and 15th day following inoculation. The tumorous tissue was found to contain a single type of cells. The polygonal cells were loosely arranged, without intercellular at taching structures between them. Pseudopodia projecting into the intercellular space and rows of pinocytotic intracellular vesi cles pointed ...
