AI Article Synopsis
- Lymphoma affecting the dura mater is rare and primarily linked to extranodal marginal zone lymphoma of MALT type.
- A case is presented involving a patient with a meningeal tumor identified as a B-cell lymphoproliferative disorder resembling chronic lymphocytic leukemia.
- The detection of trisomy 3 in the patient's bone marrow suggests that CD5(+) MALT lymphoma is a critical consideration, although it's not previously documented in dural lymphoma.
Article Abstract
Lymphoma manifestations of the dura mater are extremely rare and have mostly been attributed to extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) type. We report a patient with an isolated meningeal tumor, identified as a B-cell lymphoproliferative disorder with typical B-cell chronic lymphocytic leukemia immunophenotype. Because of the subclinical detection of trisomy 3 in the bone marrow by cytogenetic analysis and interphase fluorescence in situ hybridization, CD5(+) MALT is an important differential diagnosis; however, to our knowledge, this entity has never been reported in the context of dural lymphoma.

Introduction: Hepatitis C virus (HCV) infection represents a significant global health burden, particularly due to its extrahepatic immune-mediated manifestations, such as mixed cryoglobulinemia, associated vasculitis (CryoVas), and non-Hodgkin B-cell lymphoma (B-NHL), which pose significant challenges. The advent of direct-acting antiviral (DAA) has changed the therapeutic landscape for HCV-related complications.
Areas Covered: This review explores the evolving epidemiology and management of HCV extrahepatic manifestation and lymphoproliferative disorders in the era of DAAs.

Background: Klinefelter syndrome is considered one of the most common sex chromosome disorders affecting males. The presence of an extra X chromosome can alter the tendency to develop various cancers, including lymphomas. Lacrimal gland lymphoma is a disease of the elderly, with a median age of presentation of 70 years.

Preface And Importance: Burkitt's lymphoma (BL) is a relatively rare post-transplant lymphoproliferative disorder (PTLD), and there is currently limited research on the occurrence of BL following adult liver transplantation.
Case Introduction: We report a 45-year-old male who developed BL that rapidly progressed at seven years after left liver transplantation. The patient eventually abandoned treatment due to severe clinical complications.

Chronic lymphocytic leukemia (CLL) is a lymphoproliferative disorder that affects the bone marrow, lymph nodes, and spleen, and is associated with certain complications. One of the complications of CLL is acquired immunodeficiency, leading to a predisposition for prolonged respiratory viral and bacterial infections. This publication presents a clinical case of a prolonged and severe course of COVID-19 in a patient with CLL, who was successfully treated with immunoglobulin replacement therapy.

Background: Activated Phosphoinositide 3-Kinase (PI3K) δ Syndrome (APDS), an inborn error of immunity due to upregulation of the PI3K pathway, leads to recurrent infections and immune dysregulation (lymphoproliferation and autoimmunity).
Methods: Clinical and genetic data of 28 APDS patients from 25 unrelated families were collected from fifteen Italian centers.
Results: Patients were genetically confirmed with APDS-1 (n = 20) or APDS-2 (n = 8), with pathogenic mutations in the PIK3CD or PIK3R1 genes.
