Myelodysplastic/myeloproliferative neoplasms (MDS/MPN) represent not a single disease, but a diverse collection of conditions, progressively categorized based on recurring genetic anomalies. Chromosomal translocations of meningioma 1 (MN1) and ETS variant 6 (ETV6) genes are exceedingly rare, but repeatedly seen within the context of myeloid neoplasms. A case study presents a patient who experienced a myelodysplastic/myeloproliferative neoplasm featuring neutrophilia, which then progressed to an extramedullary T-lymphoblastic crisis, the only discernible chromosomal abnormality being the t(12;22)(p13;q12) translocation. This case mirrors the clinical and molecular hallmarks of myeloid/lymphoid neoplasms, particularly those characterized by a rise in eosinophil counts. Treating this patient proved exceptionally difficult, given the disease's exceptional resistance to chemotherapy, with only allogenic stem cell transplantation offering a potential cure. These genetic alterations, unlike those previously reported in association with this clinical presentation, suggest a hematopoietic neoplasm originating from an early, undifferentiated precursor cell. Furthermore, it highlights the critical role of molecular characterization in categorizing and predicting the course of these entities.

Latent iron deficiency, a condition characterized by depleted iron stores in the body without accompanying anemia, presents a significant diagnostic hurdle. The amount of hemoglobin found in reticulocytes (Ret-Hb) is directly linked to the functional iron supply for heme synthesis within erythroblasts. HA15 In conclusion, Ret-Hb has been proposed as a valuable indicator for iron status.
Assessing the contribution of Ret-Hb in recognizing subclinical iron deficiency, as well as its application in screening for iron deficiency anemia.
At Najran University Hospital, researchers investigated 108 individuals in a study, 64 of whom displayed iron deficiency anemia (IDA) and 44 of whom exhibited normal hemoglobin levels. Comprehensive blood tests, including complete blood count (CBC), reticulocyte percentage, Ret-Hb, serum iron, total iron-binding capacity (TIBC), and serum ferritin, were administered to all patients.
IDA patients exhibited a marked reduction in Ret-Hb levels when contrasted with non-anemic individuals, a threshold of 212 pg signifying the presence of IDA (values below this level indicating IDA).
In conjunction with complete blood count (CBC) parameters and indices, the measurement of Ret-Hb serves as an easily accessible predictive marker for both iron deficiency (ID) and iron deficiency anemia (IDA). Lowering the Ret-Hb cut-off value has the potential to improve the diagnostic utility of Ret-Hb as a screening tool for identifying iron deficiency anemia cases.
Not only CBC parameters and indices, but also Ret-Hb measurement, furnishes an accessible predictive marker for both iron deficiency (ID) and iron deficiency anemia (IDA). A lowered Ret-Hb cut-off value might permit a broader application of this measurement in the identification of individuals with iron deficiency anemia.

Spindle cell morphology, a rare feature, can be observed in diffuse large B-cell lymphoma cases. The 74-year-old male's initial presentation involved a right supraclavicular (lymph) node enlargement. A proliferation of spindle-shaped cells, marked by a slender cytoplasm, was ascertained through histological analysis. To rule out tumors like melanoma, carcinoma, and sarcoma, an immunohistochemical panel was employed. The lymphoma's cell-of-origin subtype was categorized as germinal center B-cell-like (GCB) according to Hans' criteria (CD10-negative, BCL6-positive, MUM1-negative), coupled with the absence of EBER and BCL2, BCL6, and MYC rearrangements. A custom gene panel of 168 genes, specifically designed to profile mutations in aggressive B-cell lymphomas, revealed mutations in ACTB, ARID1B, DUSP2, DTX1, HLA-B, PTEN, and TNFRSF14. HA15 The LymphGen 10 classification tool's results indicated an ST2 subtype prediction for this specific case. Within the immune microenvironment, a moderate level of M2-like tumor-associated macrophages (TAMs) was observed, characterized by positive staining for CD163, CSF1R, CD85A (LILRB3), and PD-L1; this was accompanied by a moderate infiltration of PD-1-positive T cells and a low frequency of FOXP3-positive regulatory T lymphocytes (Tregs). Immunohistochemical analysis revealed a complete lack of PTX3 and TNFRSF14 expression. Unexpectedly, the lymphoma cells presented positivity for HLA-DP-DR, IL-10, and RGS1, which serve as indicators of a poor prognosis for diffuse large B-cell lymphoma. R-CHOP therapy, in conjunction with other treatments, facilitated the patient's attainment of a metabolically complete response.

Although daprodustat, an inhibitor of hypoxia-inducible factor prolyl hydroxylase, and dapagliflozin, an inhibitor of sodium-glucose cotransporter 2, are approved in Japan for renal anemia treatment, their efficacy and safety haven't been evaluated in the context of patients 80 years or older with low-risk MDS-related anemia. Two men and a woman, aged over 80, formed the basis of this case series. They exhibited low-risk myelodysplastic syndrome (MDS)-related anemia, coupled with chronic kidney disease stemming from diabetes mellitus (DM). All were transfusion-dependent, and erythropoiesis-stimulating agents had proven ineffective. Following daprodustat and additional dapagliflozin treatment, all three patients became transfusion-independent for red blood cells, and were observed for over six months. Daily oral daprodustat administration yielded good results in terms of patient tolerance. No fatalities or cases of acute myeloid leukemia were documented during the >6-month post-daprodustat-initiation follow-up period. These findings support the efficacy of a daily combination therapy consisting of 24 mg of daprodustat and 10 mg of dapagliflozin for managing low-risk MDS-related anemia. Further research is crucial to understand the synergistic benefits of daprodustat and dapagliflozin in long-term management strategies for low-risk myelodysplastic syndromes (MDS). Their impact on chronic kidney disease-related anemia arises from promoting endogenous erythropoietin production and correcting iron metabolism.

Essential thrombocythemia (ET) and polycythemia vera (PV), examples of myeloproliferative neoplasms (MPNs), are seldom observed during pregnancy. These factors prove harmful, as they are correlated with increased chances of thromboembolic, hemorrhagic, or microcirculatory disturbances, or placental dysfunction, that can cause fetal growth restriction or loss. HA15 To lessen pregnancy complications, low-dose aspirin alongside low-molecular-weight heparin (LMWH) are frequently employed; interferon (IFN) remains the only viable cytoreductive treatment for pregnant women with MPN, when live birth is a consideration. Within the confines of South Korea's interferon availability, limited to ropeginterferon alfa-2b, we report a case of its use during pregnancy in a patient with myeloproliferative neoplasm (MPN). A 40-year-old woman, diagnosed with low-risk polycythemia vera (PV) in 2017, had been receiving phlebotomy, hydroxyurea (HU), and anagrelide (ANA) treatment for four years, and was confirmed pregnant at five weeks gestation on December 9th, 2021. The cessation of HU and ANA treatments resulted in a substantial improvement in the patient's blood cell counts. Notably, the platelet count saw a significant increase, rising from 1113 x 10^9/L to 2074 x 10^9/L (normal range 150-450 x 10^9/L). A concurrent elevation in white blood cell count was also observed, from 2193 x 10^9/L to 3555 x 10^9/L (normal range 40-100 x 10^9/L). With the significant risk of complications posing a considerable threat, we opted for a decisive cytoreductive strategy; ropeginterferon alfa-2b, the sole interferon agent obtainable in South Korea, was our chosen treatment modality. The pregnant patient experienced eight cycles of ropeginterferon alfa-2b treatment across six months, culminating in a delivery without any issues relating to either the mother or the baby. The clinical presentation of this case highlights the need to consider a range of treatment options for MPN patients who are pregnant or planning a pregnancy. Further evaluation is essential to assess the safety and efficacy of ropeginterferon alfa-2b in this population.

A primary cardiac lymphoma (PCL), arising from non-Hodgkin's lymphoma, is a very uncommon clinical scenario. Owing to its prevalence of 1% among cardiac tumors, the lesion's location on the right side of the heart and its ambiguous presenting symptoms and signs frequently hinder diagnosis, thus contributing to delayed diagnosis and a poor prognosis. In this case study, a middle-aged male patient was found to have PCL, characterized by an unexplained fever, through the utilization of F18-fluorodeoxyglucose positron emission tomography (18FDG-PET). In cases of pyrexia of unknown origin (PUO), particularly when a tumor is the suspected cause, PET-CT is a highly valuable resource. Its ability to precisely target the diseased area helps to select the correct course of action for speedy tissue analysis. Cases of PUO and PCL, mimicking the characteristics of atrial myxoma, should prompt physician consideration.

Primary cutaneous B-cell lymphomas (PCBCLs), a rare variant of non-Hodgkin lymphoma (NHL), are distinguished by their specific clinical and biological characteristics. Previous studies have thoroughly examined the occurrence of autoimmune or neoplastic comorbidities in NHL patients, but these findings have limited direct relevance to PCBCLs. The frequency of relevant medical conditions, such as autoimmune and neoplastic disorders, was the target of our investigation among subjects with PCBCL. Utilizing a retrospective observational study, we evaluated 56 patients diagnosed with PCBCL histologically and 54 control individuals, matched according to age and sex. The results displayed a statistically significant correlation, between neoplastic comorbidities generally (411% vs. 222%, p = 0.0034) and specifically hematological malignancies (196% vs. 19%, p = 0.00041), and PCBCL, compared to control groups. Comparing the frequencies of autoimmune comorbidities (214% vs. 93%, p = 0.1128) and chronic viral hepatitis (71% vs. 0%, p = 0.1184) yielded no statistically significant results.
