The myeloid cell line normally produces granulocytes, erythrocytes, thrombocytes, macrophages and mast cells; the lymphoid cell line produces B, T, NK and plasma cells. Lymphomas, lymphocytic leukemias, and myeloma are from the lymphoid line, while acute and chronic myelogenous leukemia, myelodysplastic syndromes and myeloproliferative diseases ...
Epstein–Barr virus-associated lymphoproliferative diseases are a group of benign, premalignant, and malignant diseases of lymphoid cells (i.e., B cells, T cells, NK cells, and histiocytic-dendritic cells) in which one or more of these cell types is infected with the Epstein–Barr virus (EBV). The virus may be responsible for the development ...
Diffuse large B-cell lymphoma is the most common of the large-cell lymphomas. MeSH now classifies the phrase "large-cell lymphoma" under "Diffuse large B cell lymphoma". [2] Many other B-cell lymphomas feature large cells: [citation needed] Angiocentric lymphoma; Burkitt's lymphoma; Follicular large-cell lymphoma; Immunoblastic lymphoma
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]
Microscopic examination of the lymph node biopsy reveals complete or partial effacement of the lymph node architecture by scattered large malignant cells known as Reed-Sternberg cells (RSC) (typical and variants) admixed within a reactive cell infiltrate composed of variable proportions of lymphocytes, histiocytes, eosinophils, and plasma cells.
Intravascular lymphomas (IVL) are rare cancers in which malignant lymphocytes proliferate and accumulate within blood vessels. Almost all other types of lymphoma involve the proliferation and accumulation of malignant lymphocytes in lymph nodes, other parts of the lymphatic system (e.g. the spleen), and various non-lymphatic organs (e.g. bone marrow and liver) but not in blood vessels.
MALT lymphoma (also called MALToma) is a form of lymphoma involving the mucosa-associated lymphoid tissue (MALT), frequently of the stomach, but virtually any mucosal site can be affected. It is a cancer originating from B cells in the marginal zone of the MALT.
The tissues involved in THRLBCL commonly show an effacement of their normal architecture by a diffusely growing infiltrate of non-malignant T-cell lymphocytes, histiocytes, and neoplastic (i.e. malignant) B-cells. The malignant B-cells represent <10% of the cells in these lesions [3] and bear resemblances to centroblast, immunoblasts, and/or ...
