Overview
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 insufficien because they 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 the 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 the diagnosis of diffuse large B-cell lymphoma (DLBCL).[6]
- A chromosomal translocation t(11:14) is definitive for the diagnosis of mantle cell lymphoma.[7]
