There have been major advances in the treatment of patients with CLL over the past 10 years or so. [17] Although this disease remains incurable, therapies such as Bruton tyrosine kinase inhibitors ( including ibrutinib, acalabrutinib , and zanubrutinib ), BCL-2 inhibitors ( including venetoclax ), and phosphatidylinositol 3-kinase inhibitors ...
Acute lymphoblastic leukemia (ALL) is a cancer of the lymphoid line of blood cells characterized by the development of large numbers of immature lymphocytes. [1] Symptoms may include feeling tired, pale skin color, fever, easy bleeding or bruising, enlarged lymph nodes, or bone pain. [1]
The tonsils and cervical lymph nodes in these cases are hyperplasic and contain mixtures of normal-appearing lymphocytes, activated lymphocytes, plasma cells, and Reed–Sternberg-like cells. [16] Many of these normal-appearing and activated B cells and a small percentage of the tissue's T and NK cells are EBV+ with the virus being mostly in ...
Within the four groups for NHL are over 60 specific types of lymphoma. [8] [9] Diagnosis is by examination of a bone marrow or lymph node biopsy. [1] Medical imaging is done to help with cancer staging. [1] Treatment depends on whether the lymphoma is slow- or fast-growing and if it is in one area or many areas. [1]
Hairy cell leukemia is an uncommon hematological malignancy characterized by an accumulation of abnormal B lymphocytes. [1] The incidence of hairy cell leukemia (HCL) is 0.28-0.30 cases per 100,000 people in Europe and the United States and the prevalence is 3 cases per 100,000 in Europe with a lower prevalence in Asia, Africa and the Middle East.
Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) is a slow-growing CD20 positive form of Hodgkin lymphoma, a cancer of the immune system's B cells. [1] [2]NLPHL is an uncommon sub-type of Hodgkin lymphoma, making up 5-10% of Hodgkin lymphomas. [3]
It is a life-threatening disease of severe hyperinflammation caused by uncontrolled proliferation of benign lymphocytes and macrophages that secrete high amounts of inflammatory cytokines. It is classified as one of the cytokine storm syndromes. There are inherited and non-inherited (acquired) causes of HLH.
Reactive lymphocytes have been found to accumulate in areas of inflammation like the liver and pharynx of individuals with infectious mononucleosis and skin window preparations. In infectious mononucleosis, the atypical lymphocytes are one component of a normal immune system that helps to control potentially fatal Epstein-Barr virus -induced B ...
