Myeloid sarcoma (MS) with either primary or secondary prostate involvement is extremely rare. Its diagnostic is particularly challenging when prostate lesion precedes the systemic manifestation of a myeloproliferative disorder. We report such a case in a 44-year-old man with a prostate mass as a first manifestation of myeloid sarcoma associated with acute myeloid leukemia (AML). The diagnosis of lymphoproliferative disorder was suspected in the prostate magnetic resonance imaging (MRI) and MS was confirmed after transrectal ultrasound-guided prostate core biopsy...

Myeloid sarcoma is a rare malignant extramedullary neoplasm of myeloid precursor cells. The majority of these cases occur in patients with known leukemia or those who eventually develop the disease. It can occur in various sites but sinonasal cavity involvement along with invasive fungal infection is exceedingly rare.

Acute myeloid leukemia (AML) is a heterogeneous malignant disorder derived from the myeloid hematopoietic cells that accounts for ~80% of all adult acute leukemia. Numerous studies have shown that drug resistance not only exists against conventional chemotherapeutic drugs, but also limits the efficacy of new biological agents. Therefore, it is important to identify the mechanisms behind chemoresistance and seek therapeutic strategies to enhance efficacy in AML chemotherapy. MicroRNA (miR)-217 has been recognized as a tumor suppressor that is downregulated in various types of cancer, however the mechanisms behind the expression and function of miR-217 in AML have not yet been recognized...

A key task in developing the field of personalized cancer therapy is the identification of novel molecular targets that enable treatment of cancers not susceptible to other means of specific therapy. The collagen receptor uPARAP/Endo180 is overexpressed by malignant cells in several non-epithelial cancers, notably including sarcomas, glioblastomas and subsets of acute myeloid leukemia. In contrast, in healthy adult individuals, expression is restricted to minor subsets of mesenchymal cells. Functionally, uPARAP/Endo180 is a rapidly recycling endocytic receptor that delivers its cargo directly into the endosomal-lysosomal system, thus opening a potential route of entry into receptor-positive cells...

BACKGROUND: Myeloid sarcoma (MS) is characterized by extramedullary infiltration by immature myeloid cells. Owing to rarity of this disease, the clinical features and overall outcomes are yet to be clarified. OBJECTIVE: To define clinical characteristics, epidemiology, pathologic findings, treatment options and outcomes in MS. METHODS: We conducted a retrospective review of 23 patients diagnosed with MS at our institute over a period of 13 years (2002-2015)...

The purpose of the Papanicolaou (Pap) smear is to detect primary squamous lesions of the uterine cervix. Although most successful at detection of squamous lesions, the Pap may also detect metastatic carcinomas, sarcomas, and melanomas. We report two rare cases of myeloid sarcoma (MS) of the uterine cervix identified on screening Pap smears with concurrent confirmatory cervical biopsies. The purpose of our study is to identify and report cytologic features of MS on Pap smears utilizing a liquid-based ThinPrep method, which has not been previously documented in literature...

T cell transcription factor GATA-3, known to play a role in early T cell development and in the development of T cell neoplasms, is expressed at high levels in fetal and adult thymus, as well as in acute leukemias with T-cell differentiation, including T lymphoblastic leukemia/lymphoma (22/22 cases), early T cell precursor (ETP) lymphoblastic leukemia (11/11 cases), and mixed phenotype acute leukemia, T/myeloid (4/5 cases), but only rarely in acute myeloid leukemia/myeloid sarcoma (1/36 cases), and not in B lymphoblastic leukemia (0/16 cases)...

BACKGROUND: A large number of chromosomal translocations of the human KMT2A gene, better known as the MLL gene, have so far been characterized. Genetic rearrangements involving KMT2A gene are frequently involved in lymphoid, myeloid and mixed lineage leukemia. One of its rare fusion partners, the mastermind like 2 (MAML2) gene has been reported in four cases of myeloid neoplasms after chemotherapy so far: two acute myeloid leukemias (AML) and two myelodysplasic syndrome (MDS), and two cases of secondary T-cell acute lymphoblastic leukemia (T-ALL)...

Granulocytic Sarcomas (GS) also called as Myeloid Sarcomas (MS) or chloromas are the representatives of extramedullary infiltrates of immature myeloid cells including myeloblasts, promyelocytes and myelocytes. Primary cardiac malignancies per se are rare and infiltration of cardiac muscles by secondary malignant cells is also an uncommon finding. Out of these cardiac tumors, contribution of Cardiac Myeloid Sarcoma (CMS) is even more smaller thereby limiting our knowledge about this rare entity. Because of its very lower incidence, an exact guideline for diagnosis and management is still missing and usually haematologists around the world are treating CMS based on their clinical acumen...

The targeted delivery of tumor necrosis factor-α (TNF-α) with antibodies specific to splice isoforms of fibronectin [e.g., F8-TNF, specific to the extra-domain A (EDA) domain of fibronectin] has already shown efficacy against experimental sarcomas but has not yet been investigated in orthotopic sarcomas. Here, we investigated F8-TNF in a syngeneic K7 M2-derived orthotopic model of osteosarcoma as a treatment against pulmonary metastases, the most frequent cause of osteosarcoma-related death. Immunofluorescence on human osteosarcoma tissue confirmed the presence of EDA in primary tumors (PTs) as well as metastases...

Myeloid sarcoma is a rare solid tumour composed of primitive precursors of granulocytic series of white blood cells involving extramedullary anatomic site. Here we report the case of a 10-month-old with testicular swelling, who was finally diagnosed with granulocytic sarcoma. This case demonstrates that Granulocytic sarcoma should be considered as a part of the differential diagnosis for testicular swelling in spite of having normal peripheral counts and absence of hepatosplenomegaly.

Importance: Although the increased incidence of second primary malignant neoplasms (SPMs) is a well-known late effect after cancer, few studies have compared survival after an SPM to survival of the same cancer occurring as first primary malignant neoplasm (PM) by age. Objective: To assess the survival impact of SPMs in adolescents and young adults (AYAs) (15-39 years) compared with that of pediatric (<15 years) and older adult (≥40 years) patients with the same SPMs...

Myeloid or granulocytic sarcoma (GS) is a tumoral lesion consisting of immature granulocytic cells. It is a rare entity during the course of CML patients especially after allogeneic stem cell transplantation (SCT). Relapse without bone marrow involvement is much rarer. We report a case of CML patient who relapsed with isolated granulocytic sarcoma after allogeneic SCT during cytogenetic and molecular remission. 28-year-old male was diagnosed as CML and allogeneic SCT was performed because of refractory disease to tyrosine kinase inhibitors...

Objectives: We report a rare case of CD4- cutaneous blastic plasmacytoid dendritic cell neoplasm (BPDCN) with a novel PBRM1 mutation. Methods: An 11-year-old girl presented with an enlarged mass on her left arm and underwent an incisional biopsy. Results: Histopathologic examination and immunohistochemistry studies showed a monotonous proliferation of blasts that were CD4-, CD56+, and CD123+. There was no evidence of leukemic dissemination...

Post-surgical tumor recurrence is a common problem in cancer treatment. In the present study, the role of neem leaf glycoprotein (NLGP), a novel immunomodulator, in prevention of post-surgical recurrence of solid sarcoma was examined. Data suggest that NLGP prevents tumor recurrence after surgical removal of sarcoma in Swiss mice and increases their tumor-free survival time. In NLGP-treated tumor-free mice, increased cytotoxic CD8+ T cells and a decreased population of suppressor cells, especially myeloid-derived suppressor cells (MDSCs) was observed...

Myeloid sarcoma is an extramedullary collection of blasts of the myeloid series that partially or totally effaces the architecture of the tissue in which it is found. These tumors have been described in many sites of the body, but the skin, lymph nodes, gastrointestinal tract, bone, soft tissue, and testes are most common. They can arise in a patient following the diagnosis of acute myeloid leukemia, but they may also be precursors of leukemia and should be considered diagnostic for acute myeloid leukemia. The differential diagnosis of this neoplasm includes malignant lymphoma, with which it is often mistaken, leading to diagnostic and therapeutic delays...
