Splenic marginal zone lymphoma (SMZL) is a type of marginal zone lymphoma, a cancer made up of B-cells that replace the normal architecture of the white pulp of the spleen. The neoplastic cells are both small lymphocytes and larger, transformed lymphoblasts , and they invade the mantle zone of splenic follicles and erode the marginal zone ...
Non-Hodgkin’s lymphoma (NHL) is one of the most common forms of blood cancer.1 The American Cancer Society estimates that about 81,560 people in the U.S. will be diagnosed with NHL and about ...
Histology of a normal lymphoid follicle, with marginal zone annotated at bottom.. Numerous factors appear to be involved in the development of EMZL. In a small number of cases where there is a family history of a blood cancer particularly leukemia, or a number of autoimmune diseases such as Sjögren syndrome and lupus erythematosus, there is seen to be an increased frequency.
Lymphoma is a group of blood and lymph tumors that develop from lymphocytes (a type of white blood cell). [7] The name typically refers to just the cancerous versions rather than all such tumours. [7] Signs and symptoms may include enlarged lymph nodes, fever, drenching sweats, unintended weight loss, itching, and constantly feeling tired.
In order to be diagnosed with CLL, the patient must have a white blood cell count greater than 5 billion cells per liter (L) (5x10 9 /L) of blood. If CLL-type cells are mainly found in the lymph nodes or lymphoid tissue (such as the spleen), a diagnosis of small lymphocytic lymphoma (SLL) is made. [43]
Such blast cells may also be observed in the circulation, bone marrow, or other tissues and suggest BPDCN. However, the diagnosis of this disease requires determination that these cells are pDC blast cells rather than AML, T-cell lymphoblastic lymphoma (TCLL), or aggressive NK-cell leukemia (NKL) blast cells. Various studies have offered ...
The diagnosis of MBL in these patients depends on finding 0.5-5x10 9 monoclonal B cells that express the makers characteristic of CLL/SLL MLB, atypical CLL/SLL MLB, non-CLL/SLL MLB, or MLB-MZ. [3] However, individuals with CBL-MZ commonly present with B-cell blood counts that are extremely high (>4.0x10 9 ; range 3.0x10 9 /L to 37.1x10 9 /L ...
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.
