what are marginal zone lymphomas?
233564
Marginal zone lymphomas are types of slow-growing (low-grade) non-Hodgkin lymphomas that develop from B cells. They are called marginal zone lymphomas because they develop in a particular region found at the edge of normal lymphoid tissues (collections of lymphocytes) called the marginal zone.

Non-Hodgkin lymphoma (NHL) is one of the most common cancers in the United States, accounting for about 4% of all cancers. The American Cancer Society's estimates for non-Hodgkin's lymphoma in 2020 are: About 77,240 people (42,380 males and 34,860 females) will be diagnosed with NHL.

Chronic lymphocytic leukemia (CLL) is a type of cancer of the blood and bone marrow — the spongy tissue inside bones where blood cells are made. The term "chronic" in chronic lymphocytic leukemia comes from the fact that it typically progresses more slowly than other types of leukemia.

CLL has 'leukaemia' in its name because it affects the blood. SLL is another form of the same disease and it mainly affects the lymph nodes (glands), which is why it is called a 'lymphoma'. Both forms of the disease are low-grade (slow-growing) and are often grouped as non-Hodgkin lymphomas.

One symptom of lymphoma can be the development of lumps under the skin, usually in the neck, armpit, or groin. The lumps have a rubbery feel and are usually painless.

Stage 4 lymphoma means that cancer has spread to an organ external to the lymphatic system. The survival rates vary widely depending on an individual's risk factors and type of cancer. The survival rate of stage 4 lymphoma is lower than that of the other stages, but doctors can cure the condition in some cases.

T-cell lymphomas are non-Hodgkin lymphomas that develop from T lymphocytes. Some T-cell lymphomas develop in the skin. We have separate information on T-cell skin lymphomas.

Central nervous system lymphoma is a rare non-Hodgkin lymphoma in which malignant (cancer) cells from lymph tissue form in the brain and/or spinal cord (primary CNS) or spread from other parts of the body to the brain and/or spinal cord (secondary CNS).

In Hodgkin lymphoma, B-lymphocytes (a particular type of lymphocyte) start to multiply in an abnormal way and begin to collect in certain parts of the lymphatic system, such as the lymph nodes (glands). The affected lymphocytes lose their infection-fighting properties, making you more vulnerable to infection.

Lymphoproliferative disorders (LPD)[1][2] comprise a heterogeneous group of diseases characterized by uncontrolled production of lymphocytes that cause monoclonal lymphocytosis, lymphadenopathy and bone marrow infiltration. These diseases often occur in immunocompromised individuals.

Stage II. Hodgkin lymphomais found in two or more lymph node areas on the same side of the diaphragm (the muscle beneath the lungs that moves up and down to help you breathe).

EBV infection increases a person's risk of getting nasopharyngeal cancer (cancer of the area in the back of the nose) and certain types of fast-growing lymphomas such as Burkitt lymphoma. It may also be linked to Hodgkin lymphoma and some cases of stomach cancer.

Follicular lymphoma (FL) is a slow-growing type of non-Hodgkin lymphoma. It develops when B-cells (also called B-lymphocytes) become abnormal. B-cells are white blood cells that fight infection. The abnormal B-cells (lymphoma cells) usually build up in lymph nodes, but they can affect other parts of the body.

Background. Canine T‐cell lymphoma (TCL) is clinically and histologically heterogeneous with some forms, such as T‐zone lymphoma (TZL), having an indolent course. Immunophenotyping is an important tool in the classification of TCL in people, and can be equally useful in dogs.

Burkitt and Burkitt-like lymphoma Treatment of limited stage (stage I and II) Burkitt lymphomas is usually very successful, with a long-term survival rate of over 90%. The long-term survival rate for children with more advanced (stage III or IV) Burkitt lymphoma ranges from about 80% to 90%.
