Granulocytic sarcoma (GS) represents a rare type of extramedullar manifestation from the acute myeloid leukaemia (AML). We report the case of a patient with recurrences of AML M4eo leukaemia in the uterus and the small intestine at 3 and 5 years, respectively, after matched related peripheral blood stem cell transplantation (PBSCT). The patient underwent the withdrawal of immunosuppression, hysterectomy, and local irradiation at first relapse, as well as systemic chemotherapy and donor lymphocyte infusions at second recurrence, inducing a second and third complete remission, respectively. At year six after transplantation, the patient experienced disease progression by meningeosis leukaemia to which she succumbed despite intrathecal chemotherapy. Following allogeneic stem cell transplantation, awareness for atypical manifestations of granulocytic sarcoma appears prudent, the cellular immunotherapy should aim at immunological disease control.

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.

A 46-year-old female presented with back pain associated with progressive bilateral lower extremity weakness and paresthesia. Imaging studies revealed a retroperitoneal mass with severe spinal compression. Histological sections showed blastoid cells with large nuclei, irregular membranes, fine chromatin, and prominent nucleoli.

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.
