818 Possible Causes for Leukocytosis, Lymphocytosis

  • Infectious Mononucleosis

    An atypical lymphocytosis of at least 20 percent or atypical lymphocytosis of at least 10 percent plus lymphocytosis of at least 50 percent strongly supports the diagnosis[ncbi.nlm.nih.gov] Sprunt, Frank Alexander Evans (1889-1956): Mononuclear leukocytosis in reaction to acute infection (infectious mononucleosis).[whonamedit.com] Lymph node biopsy was performed and he was diagnosed as atypical infectious mononucleosis (absence of fever, pharyngitis, lymphocytosis and negative atypical lymphocytosis[ncbi.nlm.nih.gov]

  • Toxoplasmosis

    Some patients with prolonged fever and malaise have lymphocytosis, increased suppressor T-cell counts, and a decreased helper-to-suppressor T-cell ratio.[emedicine.com]

  • Chronic Lymphocytic Leukemia

    […] in the blood and marrow only (survival 120 months) Stage I lymphocytosis and adenopathy (survival 95 months) Stage II lymphocytosis, splenomegaly and/or hepatomegaly (survival[flexikon.doccheck.com] One month later, he presented with progressive leukocytosis (mostly neutrophilia) and splenomegaly.[ncbi.nlm.nih.gov] We report two cases of biclonal CLL presented with leukocytosis, typical morphological features, and distinct immunophenotype of CLL.[ncbi.nlm.nih.gov]

  • Acute Infectious Lymphocytosis

    A case of acute infectious lymphocytosis in an otherwise healthy 2-year-old child is reported.[ncbi.nlm.nih.gov] Leukocytosis Leukocytosis :Significance of Monocytosis vs Lymphocytosis Monocytosis (monocyte count greater than or equal to 10x10 9 ) may indicate : - an underlying malignancy[tcd.ie] Neutrophilic leukocytosis See Table 3.[antimicrobe.org]

  • Prolymphocytic Leukemia

    This patient's condition was diagnosed as T-cell prolymphocytic leukemia based on the findings of lymphocytosis, abnormal immunophenotype, hepatosplenomegaly, lymphadenopathy[ncbi.nlm.nih.gov] This patient presented with an asymptomatic leukocytosis and splenomegaly.[ncbi.nlm.nih.gov] T-cell prolymphocytic leukemia (T-PLL) is an uncommon chronic lymphoproliferative disorder characterized by lymphadenopathy, splenomegaly, and lymphocytosis.[ncbi.nlm.nih.gov]

  • Addison's Disease

    […] to loss of production of the hormone aldosterone hyperkalemia (raised blood potassium levels), also due to loss of production of the hormone aldosterone eosinophilia and lymphocytosis[web.archive.org] Limited laboratory studies revealed anemia, leukocytosis, and hyponatremia.[ncbi.nlm.nih.gov] FBC - there may be anaemia, mild eosinophilia and lymphocytosis. Glucose - often low in children. LFTs - may be raised liver transaminases.[patient.info]

  • Influenza

    We sought to identify certain clinical characteristics associated with a poor clinical outcome in patients acutely infected with Influenza A. We performed a retrospective chart review of inpatients with acute Influenza A infection comparing a poor outcome group (POG; n 27), defined as patients who died and/or[…][ncbi.nlm.nih.gov]

  • Hereditary Spherocytosis

    Reticulocytosis of 15 to 30% and leukocytosis are common.[merckmanuals.com] It also results in leukocytosis and thrombocytosis. On peripheral blood smear, spherocytes are unchanged or may even increase.[medcaretips.com]

  • Hairy Cell Leukemia

    We report the simultaneous presence of hairy cell leukemia, monoclonal B-cell lymphocytosis, and alpha beta CD4( ) /CD8( ) T-cell large granular lymphocytosis in a 63-year-old[ncbi.nlm.nih.gov] The 3 HCL-v patients had leukocytosis and received chemotherapy with variable outcome.[ncbi.nlm.nih.gov] A 67-year-old male was admitted because of lymphocytosis and huge splenomegaly.[ncbi.nlm.nih.gov]

  • Mantle Cell Lymphoma

    A 60-year-old male patient presented with obvious leukocytosis and progressive weakness.[ncbi.nlm.nih.gov] Asymptomatic lymphocytosis is frequently seen with ibrutinib use in mantle cell lymphoma; however, tumor lysis syndrome is an extremely rare complication.[ncbi.nlm.nih.gov] Splenomegaly is often massive, while aberrant WBC count may be seen, either as markedly high leukocytosis or pancytopenia.[symptoma.com]
