DEL is associated with more aggressive disease behavior and poorer prognosis. This study aimed to assess the impact of DEL on progression-free survival (PFS) and overall survival (OS) compared to non-DEL patients. We conducted a retrospective study at the Hospital, analyzing 177 patients diagnosed with DLBCL between March 2014 and March 2021. Patients were classified as DEL or non-DEL based on immunohistochemical analysis. Survival rates, clinical characteristics, and treatment responses were compared using Kaplan-Meier survival analysis, and multivariable Cox regression was performed to identify independent prognostic factors. Among 177 patients, 113 (63.8%) were DEL and 64 (36.2%) non-DEL. DEL patients had significantly worse outcomes, with a median follow-up of 39.4 months. The 3-year PFS (44.2% vs. 68.8%) and OS (54.9% vs. 81.3%) were significantly lower in DEL (PFS: p < 0.001; OS: p = 0.001). Median PFS in DEL was 19 months. Multivariable analysis confirmed DEL as an independent predictor of worse PFS (HR: 1.488, 95% CI: 1.091-2.03, p = 0.012) and OS (HR: 1.376, 95% CI: 1.011-1.873, p = 0.043). DEL status is strongly linked to poor survival in DLBCL, highlighting the need for targeted therapies beyond R-CHOP. Future research should explore personalized treatment strategies to improve outcomes in this high-risk group.</p>","PeriodicalId":51320,"journal":{"name":"Journal of Hematopathology","volume":"18 1","pages":"8"},"PeriodicalIF":0.6,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143651914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

She received multiagent chemotherapy with temporary resolution of her skin eruption and lymphadenopathy, but persistent bone marrow disease.

Skin biopsies demonstrated a dermal perivascular and interstitial proliferation of monotonous small T-cells without significant epidermotropism. T-cell receptor gene rearrangement studies of skin and peripheral blood specimens revealed identical clonal peaks, and peripheral blood flow cytometry showed persistence of the previously identified T-cell clone.

Although lacking eosinophilia, the patient's indolent course, characteristic skin lesions, steroid responsiveness, and pathologic features are typical of LV-HES, and the elevated IgE and STAT3 activation underscore a similar biology.

We aim to present a case of lepromatous leprosy with bone marrow involvement, detailing the clinical presentation, diagnostic evaluation, and management approach. A 65-year-old male with lepromatous leprosy and severe erythema nodosum leprosum developed pancytopenia. After undergoing comprehensive clinical evaluation, including history taking, physical examination, and laboratory investigations, bone marrow examination and molecular diagnostics using polymerase chain reaction (PCR) were performed to confirm the presence of M. leprae as an etiology for his pancytopenia. The bone marrow aspirate revealed hypercellularity with erythropoiesis and thrombopoiesis within normal limits. Foamy histiocytes with erythrophagocytosis were observed, along with the presence of M. leprae on Modified Ziehl-Neelsen stain. Molecular analysis confirmed M. leprae DNA in the bone marrow aspirate. Treatment with multi-drug therapy (MDT) and thalidomide resulted in normalization of blood counts and healing of skin lesions. This case underscores the systemic nature of leprosy and the rarity of bone marrow involvement, highlighting the importance of thorough evaluation in cases of persistent symptoms.
