Background: We present a case of focal lymphoblastic transformation to erythroid leukemia following acute myeloblastic transformation in a patient with chronic myelogenous leukemia (CML) and discuss its mechanism of occurrence and development.
Case Summary: The presence of the Philadelphia (Ph) chromosome was identified through karyotype analysis, while the fusion gene was detected using quantitative real-time polymerase chain reaction of the peripheral blood sample. Fluorescence hybridization was used to detect the expression of the gene in the lymphoma. Antigen expression and gene mutations in the primitive cells were detected by flow cytometry. The analysis confirmed the presence of CML along with focal lymphoblastic transformation to erythroid leukemia. Additionally, the patient was found to have secondary erythroid leukemia, along with multiple new gene mutations and abnormalities in complex karyotypes of chromosomes.
Conclusion: Our findings suggest a possible molecular basis for the focal lymphoblastic transformation secondary to myeloblastic transformation in patients with CML.

Unlabelled: Biochemical analyses of cerebrospinal fluid (CSF) are routinely performed at diagnosis in many pediatric oncology and hematology centers when acute leukemia is diagnosed. However, the clinical relevance of these analyses remains unclear. We conducted a retrospective analysis of biochemical CSF data from children diagnosed with acute leukemia at two French hospitals between 2016 and 2023 assessing the results in relation to the presence or absence of leukemic neuromeningeal involvement and the correlation between cytological and biochemical analyses.

Because of the close membrane apposition, there is rapid exclusion of CD45, and therefore LCK activation. Much less is known about whether spatial regulation of the intracellular face dictates LCK activity and TCR signal transduction.

Acute lymphoblastic leukemia (ALL) poses a significant challenge due to its high relapse rate despite initial chemotherapy. Cell therapy plays an important and promising role in refractory ALL cases. The aim is to present a complex case of a 20-year-old male patient with relapsed ALL and to explore the different therapeutic options of cellular therapy - allogeneic hematopoietic stem cell transplantation, donor lymphocyte infusion, and chimeric antigen receptor T - detailing the collection, processing, and infusion, as well as the associated complications and management strategies.

Purpose: Lumbar puncture is a frequently performed procedure for patients undergoing treatment for acute lymphoblastic leukemia. This brief procedure is frequently performed with sedation in young patients but with only local anesthesia in adults. Adolescent and young adult patients may be cared for by physicians with different training backgrounds and sedation preferences, making the utilization of sedation for lumbar punctures variable among providers.
