Article Abstract
Background: The morphologic features of acute lymphoblastic leukemia (ALL) overlap greatly with other blastoid-HGBL or some mature B-cell lymphomas. Blastoid morphology is currently a diagnostic challenge.
Methods And Results: Our case presents a B-ALL with surface IgD and immunoglobulin light chain Kappa restricted expression, CD13 and CD33 were partial expressed and negative for CD34. The patient achieved morphologic remission after one cycle of treatment.
Conclusions: In this case, the expression of immunophenotypic features does not clearly distinguish whether the B cells are in a mature or immature stage. In some situations, these lymphoblasts cells are hardly distinguishable from mature cells.

Background: Light chain multiple myeloma (LCMM) is a malignant hematological disease characterized by bone marrow infiltration by tumor plasma cells and the secretion of monoclonal free light chains (κ or λ). It is often di-agnosed through hypogammaglobulinemia detected by serum protein electrophoresis, followed by immunotyping showing a monoclonal band in free light chains. However, the structure of monoclonal light chains can sometimes complicate laboratory findings.

B cells are critical components of the adaptive immune system that proliferate and differentiate within the secondary lymphoid organs upon recognition of antigens and engagement of T cells. Traditional two-dimensional (2D) cell cultures fall short of replicating the intricate structures and dynamic evolution of three-dimensional (3D) environments found in lymphoid organs, prompting the development of more physiologically pertinent models. Our approach employs -hexanoyl glycol chitosan (HGC) coated ultra-low attachment (ULA) lattice plates to cultivate a 3D co-culture of CD40L-expressing MS5 stromal cells and naïve B cells derived from the peripheral blood mononuclear cells (PBMCs) of healthy human donors.

Parvovirus B19 (PVB19) is an infrequent, serious, yet treatable cause of infection in immunocompromised hosts. Neurological manifestations of PVB19 are encephalitis, encephalopathy, meningitis, cerebellar ataxia, transverse myelitis, stroke, and peripheral neuropathy. The objective is to identify the exact clinical and diagnostic features specific to parvovirus B19 encephalitis for the isolation and management of the pathology.

Immunoglobulins (IGs) made by chronic lymphocytic leukemia (CLL) B cells are unique in that they bind themselves (homo-dimerize). This interaction leads to signal transduction with functional consequences that depend on the affinity of homo-dimerization. We have studied the antigen-binding properties of the IGs from a subset of patients with CLL (Subset #4) that homo-dimerize at high affinity.

Purpose Of Review: Autoimmune nodopathies (AN) are a recognized distinct group of immune-mediated peripheral neuropathies with unique immunopathological features and therapeutic implications. This review synthesizes recent advances in their pathogenesis, diagnosis, and management, which have refined their clinical classification and informed targeted treatment strategies.
Recent Findings: AN are characterized by autoantibodies targeting surface proteins in the nodal-paranodal area (anti-contactin-1, anti-contactin-associated protein 1, anti-neurofascin-155, anti-pan-neurofascin), predominantly of IgG4 subclass.
