Splenic diffuse red pulp small B-cell lymphoma displays increased expression of cyclin D3 and recurrent CCND3 mutations.

To the editor: Splenic diffuse red pulp lymphoma (SDRPL) is a rare small B-cell neoplasm provisionally included in the category of unclassifiable splenic B-cell lymphomas/leukemias in the 2008 World Health Organization classification.[1][1] SDRPL is characterized by a diffuse pattern of involvement
