85 Possible Causes for Polyclonal B Cell Lymphocytosis

  • Persistent Polyclonal B-cell Lymphocytosis

    We report the third case of persistent polyclonal B-cell lymphocytosis in a male.[] We document a case of persistent lymphocytosis in which the characteristic binucleated circulating lymphocytes were shown immunologically to be polyclonal B-cells.[] We present a case of persistent polyclonal B-cell lymphocytosis (PPBL).[]

  • Lymphocytopenia

    B-cell lymphocytosis.[] LYMPHOCYTOSIS OF B LYMPHOCYTES Lymphocytosis can be secondary to an expansion in the numbers of B cells that are “polyclonal” in their expression of immunoglobulin.[] […] chapter include: CLL, chronic lymphocytic leukemia; EBV, Epstein-Barr virus; HIV, human immunodeficiency virus; Ig, immunoglobulin; NK, natural killer; PPBL, persistent polyclonal[]

  • Acute Infectious Lymphocytosis

    LYMPHOCYTOSIS OF B LYMPHOCYTES Lymphocytosis can be secondary to an expansion in the numbers of B cells that are “polyclonal” in their expression of immunoglobulin.[] Chromosomal instability and ATR amplification gene in patients with persistent and polyclonal B-cell lymphocytosis (PPBL). Leuk Lymphoma. 2004;45:1401-1406.[] It’s also possible to see similar lymphocytes in what’s known as polyclonal B-cell lymphocytosis, which tends to occur in young to middle-aged women who smoke.[]

  • Autoimmune Lymphoproliferative Syndrome Type 3

    Polyclonal B cell lymphocytosis with expansion of CD5 B cells was a characteristic finding.[] In the peripheral blood, the T cells showed increased expression of HLA-DR and CD57 but not CD25. CD45RA T cells were increased in the four cases studied.[]

  • Constitutional Megaloblastic Anemia due to Folate Metabolism Disorder

    B-cell lymphocytosis, Syndromic multisystem autoimmune disease due to Itch deficiency, Systemic lupus erythematosus, susceptibility to X-linked lymphoproliferative disease[] B-cell lymphocytosis Pineal parenchymal tumor of intermediate differenciation Pineal tumor of neuroepithelial tissue Pineoblastoma Pineocytoma Plaque-form urticaria pigmentosa[] […] disease, Hermansky-Pudlak syndrome with neutropenia, Immune dysregulation-polyendocrinopathy-enteropathy-X-linked syndrome, Immunodeficiency due to CD25 deficiency, Persistent polyclonal[]

  • RAS-Associated Autoimmune Leukoproliferative Disease

    (J) Peripheral blood lymphocyte gate with B-cell lymphocytosis (polyclonal) with marked increase in CD10 circulating late precursor B cells in comparison with healthy control[] Flow cytometry did not show the hallmark elevation of αβ -DNTs seen in ALPS but did document B-cell lymphocytosis and monocytosis (supplemental Table 1).[] […] that are also increased in sepsis and inflammation. 32, 34 Polyclonal B-cell lymphocytosis with circulating CD10 B cells and increased CD14 expression on granulocytes are[]

  • Hereditary Neutrophilia
