Histopathology of diffuse large B-cell lymphoma occurring in the tonsil. H&E stain. Lymphoproliferative disorders (LPDs) refer to a specific class of diagnoses, comprising a group of several conditions, in which lymphocytes are produced in excessive quantities. These disorders primarily present in patients who have a compromised immune system.
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.
It mainly affects older adults, and affects men and women almost equally. [4] White people have higher incidence rates than black and Asian people, [5] but the cause of these disparities is poorly understood. [5] Indolent lymphoma is usually considered incurable without the use of allogeneic stem cell transplantation, unless the disease is ...
Hodgkin lymphoma must be distinguished from noncancerous causes of lymph node swelling (such as various infections) and from other types of cancer. Definitive diagnosis is by lymph node biopsy (usually excisional biopsy with microscopic examination). Blood tests are also performed to assess function of major organs and safety for chemotherapy.

T-cell acute lymphoblastic leukemia (T-ALL) is a type of acute lymphoblastic leukemia characterized by an aggressive malignant neoplasm of the bone marrow. [6] Acute lymphoblastic leukemia (ALL) is a condition, wherein immature white blood cells accumulate in the bone marrow and crowd out normal white blood cells. [7]
Plasmablastic lymphoma lesions are most commonly rapidly growing, soft tissue masses [5] that may be ulcerating, bleeding, and/or painful. [6] In a recent (2020) review of published cases, individuals presenting with PBD were typically middle-aged or elderly (range 1–88 years; median age 58 tears) males (~73% of cases). [7]
B symptoms are a clear negative prognostic factor in Hodgkin lymphoma. [2] The relevance of B symptoms in non-Hodgkin lymphoma is less clear, although B symptoms tend to correlate with disease that is either more widespread or of a higher histologic grade. [3]
Micrograph showing Hodgkin's lymphoma, a type of B cell lymphoma that is usually considered separate from other B cell lymphomas. Field stain. CT scan of primary B cell lymphoma in the left ilium, as diffuse cortical and trabecular thickening of the hemipelvis, mimicking Paget's disease. [2] There are numerous kinds of lymphomas involving B cells.
