The levels of spontaneous and mitogen-induced production of pro- and anti-inflammatory cytokines were studied in patients with chronic lymphoid leukemia, non-Hodgkin's lymphocytic lymphomas, and multiple myeloma during the course of chemotherapy. Cytokine concentrations varied within a great range and did not conform to the normal distribution law. The levels of granulocyte and granulocyte-macrophage CSF were high during the debut, progress, and remission of the lymphoproliferative diseases. Imbalance of a wide spectrum of pro- and anti-inflammatory cytokines was observed during the debut and progress of the lymphoproliferative diseases, more often in chronic lymphoid leukemia and non-Hodgkin's lymphocytic lymphomas than in multiple myeloma.

Methotrexate (MTX), an antimetabolite targeting certain autoimmune conditions and various hematologic malignancies, has been associated with iatrogenic lymphoproliferative disease (LPD) primarily of B-cell lineage. Less commonly are T-cell neoplasms where primary skin involvement is considered rare. Three cases were encountered in the medical practice of one of the authors.

CD73 is ubiquitously expressed and regulates critical functions across multiple organ systems. The sequential actions of CD39 and CD73 accomplish the conversion of adenosine triphosphate to adenosine and shift the adenosine triphosphate-driven proinflammatory immune cell milieu toward an anti-inflammatory state. This immunological switch is a major mechanism by which regulatory T (Treg) cells control inflammation.

BACKGROUND Post-transplant lymphoproliferative disorder (PTLD) encompasses a group of disorders ranging from hyperplastic to malignant lymphoid proliferations in the post-transplant period owing to immunosuppression, often in the setting of EBV transformation. PTLD is a rare complication of immunosuppression that, like lymphomas, can have a variable presentation based on disease localization. We report a case of PTLD mass effect at the porta hepatis for the first time in the literature, resulting in hepatic artery stenosis (HAS) and common hepatic duct obstruction.

Background: The differential diagnosis between adult systemic EBV-positive T-cell lymphoproliferative disorders (EBV T-LPD) and angioimmunoblastic T-cell lymphoma (AITL) with multiple EBV infections is difficult, and distinguishing between the two has become a diagnostic challenge for pathologists. Given that the clinical treatment plans are different, an accurate diagnosis is a prerequisite to ensure effective treatment, therefore, it is extremely necessary and meaningful to find effective pathological indicators for distinguishing between two diseases.
Methods: We present a retrospective study comparing 7 cases of adult EBV T-LPD and 16 cases of AITL with multiple EBV infections diagnosed at our institution from 2017 to 2022.

Introduction: Tuberculosis remains a major public health problem in developing countries. Isolated splenic tuberculosis is a rare form of extrapulmonary tuberculosis, with few cases documented in the literature, occurring mainly in immunocompromised individuals. The purpose of this article is to contribute to the medical knowledge regarding this rare disease and to highlight the diagnostic challenges and management approach.
