Myeloid sarcoma is an extramedullary tumor consisting of immature hematopoietic cells of granulocytic or monocytic differentiation. While rare, it can be seen in a variety of clinical settings and is most commonly associated with acute myeloid leukemia (AML), myelodysplastic syndromes (MDS) and myeloproliferative neoplasms (MPN). We present a rare case of myeloid sarcoma occurring in the bladder of a 56 year old male. Myeloid sarcoma may be difficult to recognize due to its rarity and clinical and morphologic similarity to many other conditions; however, swift diagnosis is necessary as it is considered equivalent to AML. Prognostic indicators for myeloid sarcoma have not been well established, but survival may be improved by undergoing chemotherapy designed to treat AML.

Acute myeloid leukemias (AMLs) comprise a group of genetically heterogeneous hematological malignancies that result in the abnormal growth of leukemic cells and halt the maturation process of normal hematopoietic stem cells. Despite using molecular and cytogenetic risk classification to guide treatment decisions, most AML patients survive for less than five years. A deeper comprehension of the disease's biology and the use of new, targeted therapy approaches could potentially increase cure rates.

Acute myeloid leukemia (AML) can be presented with extramedullary manifestations, more frequently involving skin and rarely other sites, such as the urinary tract. We report the case of a 37-year-old male patient with a history of testicular cancer who presented to the emergency department with cytopenias and hematuria. Bone marrow analysis diagnosed AML (French-American-British(FAB) classificationM4 subtype, karyotype showing inv16).

Background: Ewing's sarcoma (EwS), a common pediatric bone cancer, is associated with poor survival due to a lack of therapeutic targets for immunotherapy or targeted therapy. Therefore, more effective treatment options are urgently needed.
Methods: Since novel immunotherapies may address this need, we performed an integrative analysis involving single-cell RNA sequencing, cell function experiments, and humanized models to dissect the immunoregulatory interactions in EwS and identify strategies for optimizing immunotherapeutic efficacy.

We report a 37-year-old male patient who had nonbilious vomiting, no passage of flatus, and recurring abdominal pain. This patient had de novo intestinal myeloid sarcoma (MS), a rare and chameleonic presentation of acute leukemia of myeloid origin. The initial diagnostic evaluation suggested Koch's abdomen, and surgical excision of the bowel was performed with a clinical suspicion of Koch's or lymphoma.
