Lymphomatoid granulomatosis (LYG or LG) is a very rare lymphoproliferative disorder first characterized in 1972. [1] Lymphomatoid means lymphoma -like and granulomatosis denotes the microscopic characteristic of the presence of granulomas with polymorphic lymphoid infiltrates and focal necrosis within it.
EBV+ lymphomatoid granulomatosis (EBV+ LG, also termed lymphomatoid granulomatosis [LG]) is a rare disease that involves malignant B cells and reactive, non-malignant T cells; it is almost always EBV+. [1] This LPD occurs primarily in middle aged males (male:female ratio 2:1).
Some children with autoimmune lymphoproliferative disorders are heterozygous for a mutation in the gene that codes for the Fas receptor, which is located on the long arm of chromosome 10 at position 24.1, denoted 10q24.1. [3] This gene is member 6 of the TNF-receptor superfamily (TNFRSF6).
The more aggressive forms of disease require treatment with chemotherapy, radiotherapy, immunotherapy and—in some cases—a bone marrow transplant. The use of rituximab has been established for the treatment of B-cell–derived hematologic malignancies, including follicular lymphoma (FL) and diffuse large B-cell lymphoma (DLBCL).
In immunology, immunoproliferative disorders are disorders of the immune system that are characterized by the abnormal proliferation of the primary cells of the immune system, which includes B cells, T cells and natural killer (NK) cells, or by the excessive production of immunoglobulins (also known as antibodies).
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. The most commonly used classification system is the WHO classification, a convergence of more than one, older classification systems.
This disease is known for an indolent clinical course and incidental discovery. [1] The most common physical finding is moderate splenomegaly. B symptoms are seen in a third of cases, and recurrent infections due to anaemia and/or neutropenia [6] are seen in almost half of cases. [7] [8] [9] [10]
In ICD-10, cutaneous T-cell lymphomas are classified separately. References External links. This page was last edited on 25 November 2023, at 00:25 (UTC). Text is ...
