A Case of B-Cell Lymphoblastic Lymphoma Presenting with an Isolated Epidural Mass Treated Successfully with Radiotherapy Followed by United Kingdom Acute Lymphoblastic Leukemia (UKALL) Chemotherapy Protocol.

Background: B-cell lymphoblastic lymphoma (B-LBL) is an aggressive type of non-Hodgkin lymphoma that usually involves lymph nodes, skin and soft tissue. Bone marrow and peripheral blood are normally spared from involvement in the disease. B-LBL typically forms solid masses that have similar pathologic and immunophenotypic features to their liquid counterpart, B-cell acute lymphoblastic leukemia (B-ALL).

Development and Implementation of the AIDA International Registry for Patients With VEXAS Syndrome.

Objective: The aim of this paper is to present the AutoInflammatory Disease Alliance (AIDA) international Registry dedicated to Vacuoles, E1 enzyme, X-linked, Autoinflammatory, Somatic (VEXAS) syndrome, describing its design, construction, and modalities of dissemination.

Methods: This Registry is a clinical, physician-driven, population- and electronic-based instrument designed for the retrospective and prospective collection of real-life data. Data gathering is based on the Research Electronic Data Capture (REDCap) tool and is intended to obtain real-world evidence for daily patients' management.

Practical Management of Castleman's Disease.

Castleman's disease (CD) is a rare lymphoproliferative disorder that is most commonly present in multicentric (MCD) form in association with HIV infection. Interleukin-6 (IL-6) and human herpesvirus-8 (HHV-8) play major roles in MCD pathogenesis. Important treatment options have recently become available, particularly with the introduction of IL-6 and IL-6 receptor inhibitors for the treatment of HIV-negative patients with MCD.
