Diffuse large B-cell lymphoma Lymphomas are divided into 2 groups, Hodgkin lymphoma and non-Hodgkin lymphoma (NHL), which can behave differently and need different treatment. Diffuse large B-cell lymphoma (DLBCL) is the most common type of high-grade (fast-growing) non-Hodgkin lymphoma.

- Burkitt lymphoma (BL) is a highly aggressive B-cell lymphoma. All the symptoms are caused by rapid turnover of the mature B lymphocytes and the involvement of extranodal sites and invasion of contiguous organs.atients with Burkitt-like lymphoma (BLL) may have a variable presentation compared with those with classic Burkitt lymphoma (BL). Patients with BLL usually present in their fourth or fifth decade of life.

Small cleaved cells Small cleaved cells. Small cleaved cells are a distinctive type of cell that appears in certain types of lymphoma. When used to uniquely identify a type of lymphoma, they are usually categorized as follicular (C82.0) or diffuse (C83.1). The small cleaved cells are usually centrocytes that express B-cell markers such as CD20. The disease is strongly correlated with the genetic translocation t(14;18), which results in juxtaposition of the bcl-2 proto-oncogene with the heavy chain JH locus, and thus in overexpression of bcl-2.

Small Lymphocytic Lymphoma There are over 25 subtypes of NHL, although most are diagnosed infrequently. Small lymphocytic lymphoma (SLL) is the third most commonly diagnosed subtype, after diffuse large B-cell and follicular lymphomas. It accounts for 5 to 6% of NHL cases or approximately 400 cases per year in the United States. Although some NHLs are very aggressive in nature, SLL is considered an indolent lymphoma.

Pulmonary Lymphoma In most cases, pulmonary lymphoma is classified as a low-grade (indolent) B-cell non-Hodgkin's lymphoma that develops in mucosa-associated lymphoid tissue (MALT). However, as many as twenty percent of cases are high-grade pulmonary lymphoma and present as an extremely aggressive disease.

- Burkitt's lymphoma (also called small noncleaved cell lymphoma) is a type of non-Hodgkin's lymphoma, a cancer in the lymphatic system. Non-Hodgkin's lymphoma causes the cells in your child’s lymphatic system to abnormally reproduce, eventually causing tumors to grow. 2  Non-Hodgkin's disease cells can also spread to other organs and tissues in the body. 3  Non-Hodgkin's lymphoma is the third most common childhood cancer.

- B-cell lymphomas are much more common than T-cell lymphomas and account for approximately 85 percent of all NHLs. Diffuse large B-cell lymphoma (DLBCL) is the most common form of NHL, accounting for about 30 percent of newly diagnosed cases of NHL in the United States. DLBCL occurs in both men and women, although it is slightly more common in men.

- 1 Lymphoma is cancer that develops in the lymph nodes and lymphatic system. 2  The two main types of lymphoma are non-Hodgkin's (about 90% of cases) and Hodgkin's (about 10%).ymphatic cancers are classified by the type of immune cells affected. In non-Hodgkin's lymphoma, B-cells and T-cells are affected-both being types of lymphocyte white blood cell with special roles in immunity.

Anaplastic large-cell lymphoma Anaplastic large-cell lymphoma (ALCL) is a type of non-Hodgkin lymphoma involving aberrant T-cells.It is described in detail in the Classification of Tumors of the Hematopoietic and Lymphoid Tissues edited by experts of the World Health Organisation (WHO). For the cases of systemic ALCL, the recommendation is to Manage under Aggressive Lymphoma guidelines. 2  CHOP is first line of treatment, CHOP-Rituxan in the unlikely scenario that CD20 is positive, given that CD20 is a B-cell marker.

Follicular Lymphoma Follicular lymphoma is a cancer that affects white blood cells called lymphocytes. They help your body fight infections. There are two types of lymphomas: Hodgkin's and non-Hodgkin's, based on the kind of white blood cell they affect. Follicular lymphoma is a non-Hodgkin's lymphoma. When you have follicular lymphoma, the sick blood cells can travel to many parts of your body, such as your organs, bone marrow, and lymph nodes (pea-sized glands in your neck, groin, and under your arms that are part of your immune system). The blood cells can form tumors in these places.

Germinal center B-cell like diffuse large B-cell lymphoma To address these issues, which were traditionally not resolved by morphology and phenotype, DLBCL was among the first lymphomas to be analyzed by cDNA microarray. 32, 33 Three groups were identified based on the differential expression of a large set of genes, namely germinal center-like group (GCB), activated B-cell-like group (ABC), and primary mediastinal B-cell lymphoma (PMBCL). 32, 34, 35 GCB DLBCLs express a set of genes that are associated with normal germinal center B cells, whereas ...

- Until recently it was thought that B. pertussis did not invade the tissues. However, recent studies have shown the bacteria to be present in alveolar macrophages. Clinical Features The incubation period of pertussis is commonly 7–10 days, with a range of 4–21 days, and rarely may be as long as 42 days.The clinical course of the illness is divided into three stages.ommunicability Pertussis is highly communicable, as evidenced by secondary attack rates of 80% among susceptible household contacts. Persons with pertussis are most infectious during the catarrhal period and the first 2 weeks after cough onset (i.e., approximately 21 days).

Hairy Cell Leukemia This abnormal change occurs in a white cell called a B lymphocyte. 1  B lymphocytes normally produce antibodies to help fight infections.  Hairy cells tend to accumulate in the bone marrow, liver and spleen. Even though hairy cell leukemia affects the white cells, the lymph nodes usually don't enlarge.

What Is Chronic Lymphocytic Leukemia? Large granular lymphocyte (LGL) leukemia: This is another rare form of chronic leukemia. The cancer cells are large and have features of either T lymphocytes or another type of lymphocyte called natural killer (NK) cells. Most LGL leukemias are slow-growing, but a small number are more aggressive.eukemia is different from other types of cancer that start in organs like the lungs, colon, or breast and then spread to the bone marrow. Cancers that start elsewhere and then spread to the bone marrow are not leukemia.

Diffuse Large Cell Lymphoma Currently, diffuse large B-cell lymphoma is designated under the REAL classification as classic diffuse large cell lymphoma of B-cell origin defined by the working formulation. Lymphomas of T-cell or NK-cell origin exhibit biologic and clinical features distinct from diffuse large B-cell lymphomas.
