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 ...
Reactive lymphocyte surrounded by red blood cells. In immunology, reactive lymphocytes, variant lymphocytes, atypical lymphocytes, Downey cells or Türk cells are cytotoxic (CD8 +) lymphocytes that become large as a result of antigen stimulation. Typically, they can be more than 30 μm in diameter with varying size and shape.
However, the other MLB phenotypes may progress to and/or be mimicked by various monoclonal B-cell lymphocyte malignancies. The key cell markers and other points that help distinguish the following MBL phenotypes from these malignancies include the following (refer to Table for comparisons to non-malignant predecessor cells): Atypical CLL/SLL ...
[8] [9] In CLL, the bone marrow makes too many lymphocytes, which are a type of white blood cell. [8] [9] In patients with CLL, B cell lymphocytes can begin to collect in their blood, spleen, lymph nodes, and bone marrow. [10] [4] These cells do not function well and crowd out healthy blood cells. [2] CLL is divided into two main types:
Myeloid tissue, in the bone marrow sense of the word myeloid (myelo-+ -oid), is tissue of bone marrow, of bone marrow cell lineage, or resembling bone marrow, and myelogenous tissue (myelo-+ -genous) is any tissue of, or arising from, bone marrow; in these senses the terms are usually used synonymously, as for example with chronic myeloid ...
Lymphoblasts can also refer to immature cells which typically differentiate to form mature lymphocytes. [2] Normally, lymphoblasts are found in the bone marrow, but in acute lymphoblastic leukemia (ALL), lymphoblasts proliferate uncontrollably and are found in large numbers in the peripheral blood. The size is between 10 and 20 μm. [3]
Lymphoid leukemias are a group of leukemias affecting circulating lymphocytes, a type of white blood cell.The lymphocytic leukemias are closely related to lymphomas of the lymphocytes, to the point that some of them are unitary disease entities that can be called by either name (for example, adult T-cell leukemia/lymphoma).
pcALCL lesions exhibit large malignant T-cells or null cells (i.e. cells lacking many T-cell receptor proteins) with "Hallmark" cell features of anaplasia, pleomorphism, and kidney- and horse shaped-nuclei. [24] These lesions are often limited to the dermis but can extend into the surrounding subcutaneous tissue and/or epidermis.
