Overview
Classification
Diffuse large B-cell lymphoma encompasses a biologically and clinically diverse set of diseases,[1] many of which cannot be separated from one another by well-defined and widely accepted criteria. The World Health Organization (WHO) classification system defines more than a dozen subtypes, each of which can be differentiated based on the
- Location of the tumour
- Presence of other cells within the tumour (such as T cells)
- Other illnesses related to Diffuse large B-cell lymphoma.
One of these well-defined groupings of particular note is "primary mediastinal (thymic) large B-cell lymphoma", which arises within the thymus or mediastinal lymph nodes.Template:Sfn
In some cases, a tumour may share many features with both Diffuse large B-cell lymphoma and Burkitt lymphoma. In these situations, the tumour is classified as simply “B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma”.
A similar situation can arise between Diffuse large B-cell lymphoma and Hodgkin’s lymphoma; the tumour is then classified as “B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Hodgkin’s lymphoma”.[citation needed]
When a case of Diffuse large B-cell lymphoma does not conform to any of the well-defined subtypes, and is also not considered unclassifiable, then it is classified as “diffuse large B-cell lymphoma, not otherwise specified”. The majority of Diffuse large B-cell lymphoma cases fall into this category. Much research has been devoted to separating this still-heterogeneous group; such distinctions are usually made along lines of cellular morphology, gene expression, and immunohistochemical properties.{{citation nee
