INTRODUCTION: Myeloid Sarcoma (MS) is a rare hematologic myeloid neoplasm that can involve any site of the body. It can occur as an exclusively extramedullary form or it can be associated with an acute myeloid leukemia (AML), a chronic myeloproliferative neoplasm (MPN) or a myelodysplastic syndrome (MDS) at onset or at relapse. The rarity of MS does not enable prospective clinical trials and therefore a specific multicenter register can be useful for the clinical and biological studies of this rare disease...

BACKGROUND: Myeloid sarcoma (MS) is a malignant tumor that usually occurs concomitantly with or following acute myeloid leukemia (AML). Cavernomas are benign congenital malformations that are unusual in the spine and exceedingly rare in pure extradural locations. CASE DESCRIPTION: We report a 73-year-old female with a previous medical history of AML in remission for 3 years who presented with symptoms of low back pain and right lower extremity radiculopathy. A magnetic resonance scan showed an extradural, foraminal lesion centered at the L2 level involving the right L2 nerve root...

Myeloid, plasma cell, and lymphoblastic neoplasms are expected findings in bone marrow but are much less commonly diagnosed as primary processes in lymph nodes. The objective of this review is to aid pathologists in recognizing common hematopoietic neoplasms in the unusual setting of initial presentation in lymph nodes. Review of historical background and evolution of testing strategies is presented in order to improve understanding of the need for accurate diagnosis and classification using current nomenclature...

The authors describe a case of myeloid sarcoma of the orbit in a pediatric patient. An 8-month-old male infant presented to the ophthalmology clinic with a left orbital mass, which had been increasing in size over the previous 2 months. The mass was initially diagnosed at another clinic as an infantile hemangioma, and had been treated with a topical formulation of timolol. In the ophthalmology clinic, orbital magnetic resonance imaging showed a solid enhancing mass. A biopsy was performed, and histopathology revealed myeloid sarcoma...

Solid tumor metastasis is a complex biology, impinged upon by a variety of dysregulated signaling pathways. PI3'-lipid signaling has been associated with metastasis and inflammation in many cancers, but the relationship between tumor cell-intrinsic PI3'-lipid signaling and inflammatory cell recruitment has remained enigmatic. Elevated PI3'-lipid signaling associates with progression of synovial sarcoma, a deadly soft tissue malignancy initiated by a t(X;18) chromosomal translocation that generates an SS18-SSX fusion oncoprotein...

RATIONALE: Granulocytic sarcoma (GS) is defined as leukemia infiltration in any organ other than the bone marrow. GS rarely occurs in the pancreas. Here, we present the first report of GS in the pancreas on F-fluorodexyglucose positron emission tomography/computed tomography (F-FDG PET/CT). PATIENT CONCERNS: A 19-year-old male patient with acute myeloid leukemia received a human leukocyte antigen-haploidentical stem cell transplant as a second transplant while in second complete remission...

Granulocytic sarcomas, also referred to as chloromas or myeloid sarcomas, are extramedullary neoplasms that are composed of immature myeloid cells. This uncommon disease is known to be radiosensitive. However, the total dose and dose per fraction are not standardized. In addition, during the course of radiation therapy, significant reduction of the tumor is usually obtained. Thus, target volume reduction may require an intermediate radiotherapy plan evaluation for an adaptive treatment. A second plan at mid-dose is highly recommended...

INTRODUCTION: ERG expression has been described as a frequent event in prostate cancer indicating poor prognosis and promoting oncogenesis. It has also been demonstrated in Ewing's sarcoma, acute myeloid leukemia and acute T-lymphoblastic leukemia but could not be found in other epithelial tumors, Hodgkin's or Non-Hodgkin's lymphoma. We aimed to analyze ERG expression in multiple myeloma, following an index case of a patient with metastases of unknown origin in the spine strongly expressing ERG, which were thought to be of prostatic origin but turned out to be plasmacytic lesions...

Two cases of granulocytic sarcoma (GS) with lymph node presentation without marrow involvement are presented because it is a rare presentation of acute myeloid leukemia (AML) that can coexist with or precede it and as initial symptom (case 1) or disease relapse (case 2). The most common differential diagnoses are lymphoma or solid tumor. Biopsy is essential for definitive diagnosis. Imaging studies such as positron emission tomography (PET) are very useful for staging and monitoring. The prognosis and treatment according to the literature is not different from AML...

Dioxin exposure and its effect on hematopoiesis and cancer have been largely investigated in both human and non-human settings. Here we systematically reviewed literature to address the question of what we know about TCDD biology and exposure. Most effects are due to TCDD interaction with a receptor of xenobiotics called AHR, which is ubiquitously represented and also works on hematopoietic myeloid and lymphoid stem cells, inducing proliferation and stem cell release from bone marrow to peripheral circulation...

Granulocytic sarcoma (GS) is an extremely rare condition involving infiltration of myeloblasts or immature myeloid cells in an extramedullary site. It is also known as chloroma, myeloid sarcoma or extramedullary myeloid tumor. It usually occurs concomitantly with acute myelogenous leukemia or with the onset of blastic phase of chronic myelogenous leukemia. On rare occasions, it evolves even before the onset of leukemias, and when it precedes leukemias without any overt signs, it is referred to as the primary type...

Granulocytic sarcoma (GS) is a rare extramedullary manifestation of acute myeloid leukemia (AML). GS may develop simultaneously to AML or as a relapse of leukemia, particularly following allogeneic hematopoietic stem cell transplant. Subperiosteal bone, lymph nodes and skin are commonly involved, whereas rhinopharyngeal involvement is less common, with only 14 cases reported in the literature. Due to its rarity, rhinopharyngeal GS may lead to diagnostic pitfalls, particularly when it is poorly differentiated or is without concomitant marrow involvement...

STUDY QUESTION: Are Inhibin B and testosterone levels reduced in boys with newly diagnosed cancer prior to therapy? SUMMARY ANSWER: Pretreatment serum levels of Inhibin B and testosterone are significantly reduced in boys with newly diagnosed cancer, compared to reference values. WHAT IS ALREADY KNOWN: Disease-related gonadal impairment has been demonstrated in girls and young women diagnosed with cancer, prior to therapy. STUDY DESIGN, SIZE, DURATION: We conducted a descriptive study in boys newly diagnosed with cancer between January 2006 and February 2014...

Myeloid sarcoma (MS) is an extramedullary involvement of immature myeloid proliferation. An isolated MS is defined as a myeloblastic tumor when it arises without any concomitant circulating disease. A diagnosis of MS is established using pathologic features including infiltration of myeloblasts and strong myeloperoxidase expression with negative cytokeratin immunohistochemical staining. We report a rare case of colonic MS without any peripheral blood abnormality. If the affected patient were left untreated, the MS could evolve into acute myeloid leukemia (AML) within one year...

Myeloid sarcoma (MS) is an extramedullary tumor of immature myeloid cells. We analyzed 131 patients with MS, including: (1) de novo MS; (2) MS with concomitant acute myeloid leukemia (AML); (3) MS following myelodysplastic syndrome, myeloproliferative neoplasm, or chronic myelogenous leukemia; and (4) MS as a recurrence of AML. The most common development site was the lymph node. Testicular lesions were statistically more frequent in MS as a recurrence of AML than in other types of MS (P=0.0183). MS tended to lack myeloid markers (myeloperoxidase was present in 63...

The Ewing sarcoma breakpoint region 1 (EWSR1) gene is known to fuse with various partner genes to promote the development of the Ewing sarcoma family of tumors and other sarcomas. In contrast, the association of EWSR1 chimeric fusion genes with leukemia has rarely been reported. We identified a novel EWSR1-associated chimeric fusion gene in a patient with acute myeloid leukemia harboring 46, XY, t (11; 22) (p13; q12) karyotype abnormality. The patient was refractory to intensified chemotherapy including hematopoietic stem cell transplantation...
