Overview
B-cell lymphomas include both Hodgkin's lymphomas and most Non-Hodgkin lymphomas. Excisional lymph node biopsy is the gold standard test for the diagnosis of B-cell lymphomas. It is the preferred method to protect the architecture of lymph nodes, which is crucial for pathological evaluation and classification of lymphoma.
Diagnostic Study of Choice
Study of choice
B-cell lymphomas include both Hodgkin's lymphomas and most Non-Hodgkin lymphomas.
- Excisional lymph node biopsy is the gold standard test for the diagnosis of B-cell lymphomas. It is the preferred method to protect the architecture of lymph nodes, which is crucial for pathological evaluation and classification of lymphoma.[1][2][3][4]
- Fine-needle aspiration or core-needle biopsy specimens are usually insufficient because these methods have a low ratio of malignant cells and they do not sufficiently preserve the architecture of lymph nodes.
- Diagnostic studies of B-cell lymphomas include light microscopic evaluation of pathologic sample, as well as an immunophenotypic analysis with immunohistochemistry to determine the subtype.
Diagnostic results
- The following findings on pathological evaluation are confirmatory for Hodgkin's lypmhoma:[4]
- Reed-Sternberg cells (RS)
- Lymphocyte predominant cells (LP)
- The following findings on immunophenotypic analysis are confirmatory for the following types of non-Hodgkin's lypmhoma:[5][2]
- MYC-IGH rearrangement detected by FISH in the presence of a BCL2 negative germinal centres phenotype is definitive for diagnosis of Burkitt lymphoma.
- A disrupted structure of follicle center by sheets of large cells which are positive for pan-B-cell antigens (e.g., CD20, CD79a) is definitive for diagnosis of diffuse large B-cell lymphoma (DLBCL).[6]
- A chromosomal translocation t(11:14) is definitive for diagnosis of mantle cell lymphoma.[7]
