Classification:
*Primary CNS lymphoma.
*Non-primary CNS lymphoma - see ''[[lymphoma]]'' article.
===General - primary CNS===
*Classically periventicular distribution.
*Usually large B cell; can be considered a type of [[diffuse large B cell lymphoma]] (DLBCL).
**Prognosis of CNS (DLBCL) lymphomas worse than nodal (non-CNS) DLBCL.<ref name=pmid19925562>{{cite journal |author=Raoux D, Duband S, Forest F, ''et al.'' |title=Primary central nervous system lymphoma: Immunohistochemical profile and prognostic significance |journal=Neuropathology |volume=30 |issue=3 |pages=232–40 |y...
===Microscopic===
Features:
*Large cell lymphoma.
**Size = 2x diameter normal lymphocyte.
**Nucleolus - common.
*Perivascular clustering.

===IHC===
Can be subclassified in ''GCB (germinal centre B-cell-like)'' and ''non-GCB'' by CD10, Bcl-6, MUM1/IRF-4, and Bcl-2.<ref name=pmid19925562/>
Common pattern:
*[[CD20]] +ve - key stain.
*CD3 -ve.
*Ki-67 ~40%.
