Myeloid sarcoma is an extramedullary tumor of immature granulocytic cells. It is a rare condition, most often associated with acute myeloid leukemia (AML), although in some rare cases it may present in nonleukemic patients. It should therefore be considered as a differential diagnosis of any atypical cellular infiltrate. It may occur at any site, leading to very varied clinical presentations. Diagnosis is challenging and relies on a high index of suspicion as well as radiology, histology, immunophenotyping, and molecular analyses, which also are essential for risk stratification and treatment planning...

BACKGROUND: The prognostic significance of extramedullary leukemia (EML) in childhood acute myeloid leukemia is not clarified. PROCEDURE: This population-based study included 315 children from the NOPHO-AML 2004 trial. RESULTS: At diagnosis, 73 (23%) patients had EML: 39 (12%) had myeloid sarcoma, 22 (7%) had central nervous system disease, and 12 (4%) had both. EML was associated with young age (median age: 2.6 years), a high white blood cell count (median: 40 × 10(9) /l), M5 morphology (40%), and 11q23/MLL (KMT2A) rearrangements (34%)...

Posterior reversible encephalopathy syndrome (PRES) is diagnosed based on neuroradiological findings. Typically, PRES is reversible and presents with a good outcome; however, fatal outcomes have been reported. We report an autopsied case showing PRES-like neuroradiological findings associated with premedication including tacrolimus for autologous peripheral blood stem cell transplantation in a 28-year-old woman with a 2-year history of acute myeloid sarcoma/acute myeloid leukemia. Neurological examination revealed disturbed consciousness, muscle weakness in all extremities, and bilaterally diminished tendon reflexes...

Multiple nonleukemic myeloid sarcoma (MS) is a rare form of MS that is developed in multiple anatomic sites other than bone marrow at diagnosis, without a preceding myeloid neoplasm. The prevalence, prognosis, and optimal management of multiple nonleukemic MS have not been addressed. The role of allogenic or autologous hematopoietic cell transplantation (HCT) for nonleukemic MS is also less well defined. We present a case of MS characterized by systemic lymphadenopathies and multiple effusions, which presumably had a very poor prognosis...

Granulocytic Sarcoma (GS) is a rare condition with a wide list of differential diagnosis and debatable guidelines of treatment in different cancer centers. Most of literature recommended systemic chemotherapy with or without radiation therapy and small role of surgery. One of the rarest sites for myeloid sarcoma is hard palate, which usually worsen the quality of life of the patient due to difficulty in feeding, drinking and speaking. We are reporting a case of hard palatine fistula caused by granulocytic sarcoma, in which we tried to get local control of disease with 3 dimension conformal radiation therapy 3DCRT and surgery with systemic control with chemotherapy using recommendation of multidisciplinary team and targeting mainly patient quality of life...

INTRODUCTION: Myeloid sarcoma (MS) in chronic myeloid leukemia (CML) is a rare entity which is suggestive of advanced phase of the disease and poorer outcomes. There is little data in literature available regarding its presentation in medullary chronic phase (CP) as well as outcomes in the era of tyrosine kinase inhibitors (TKI) and needs to be carefully evaluated as it can present the first sign of progressive disease before haematological progression. METHODS: We identified cases of MS presenting with medullary CML-CP from January 2002 to December 2015...

Background: Myeloid sarcoma (MS) or granulocytic sarcoma is a rare tumor consisting of myeloid blasts with or without maturation occurring at anatomic sites other than the bone marrow. MS can involve any organ system but shows a predilection for skin, bone, and soft tissues of head and neck region. Case report: We report four cases of MS occurring at unusual sites, out of which three were de novo and one was associated with acute myeloid leukemia (AML). Conclusion: Although MS is associated with AML, it can rarely present without any existent hematologic disease...

Granulocytic sarcoma (GS) or chloroma, rare extramedullary manifestation of acute myeloid leukemia and not infrequently, can be presenting clinical feature. Multiple studies have demonstrated the clinical utility of fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) in early detection and follow-up assessment of GS after chemotherapy. Commonly involved areas include bones, lymph nodes, breasts, and skin and not uncommonly, the disease can be multifocal. We present a rare case of ocular GS, where FDG-PET/CT in addition to the identifying the ocular mass, revealed multiple clinically occult extramedullary lesions...

Mixed phenotypic acute leukemia (MPAL) is a rare clinical entity. MPAL associated with myeloidsarcoma (MS) is still rarer with only three cases mentioned in English literature. MS has been described in myriads of location, most commonly in skin, gums and lymph nodes. Although theoritically possible, it is very rare to find MS involving the thyroid gland. The diagnosis of MS can be elusive, very often masquerades and mislabeled as lymphoma. A high index of clinical suspicion coupled with PET/CT findings along with morphological clues and thorough peripheral blood, and bone marrow evaluation is mandatory for arriving at the definitive diagnosis...

BACKGROUND: Ewing sarcoma survivors (ESSs) are at increased risk for treatment-related complications. The incidence of treatment-related morbidity and late mortality with aging is unknown. METHODS: This study reports survival probabilities, estimated with the Kaplan-Meier method, and the cumulative incidence of cause-specific mortality and chronic conditions among ESSs in the Childhood Cancer Survivor Study who were treated between 1970 and 1986. Piecewise exponential models were used to estimate relative rates (RRs) and 95% confidence intervals (CIs) for these outcomes...

Nonleukemic myeloid sarcoma (MS) is a rare tumor that can occur in several locations without myeloid leukemia. We reported a first case of nonleukemic MS of the spleen involving the liver in a 5-month-old boy presenting with hematochezia, petechial hemorrhage, fever, and hepatosplenomegaly. Bone marrow trephine biopsy and immunophenotypic flow cytometry revealed no evidence of myeloid leukemia. The patient underwent liver biopsy and splenectomy. Clinicopathology and immunohistochemistry suggested a disseminated nonleukemic MS...

We report a 1-year-old female child presenting with hypereosinophilia who was found to have concurrent myeloid sarcoma and a central nervous system (CNS) atypical teratoid/rhabdoid tumor (AT/RT). She was later found to have a germline mutation in SMARCB1. Concurrent hematologic malignancy and CNS AT/RT have not previously been described in the context of a SMARCB1 loss-of-function germline mutation.

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...
