<span style="color:#0070C0">(General Instructions – The main focus of these pages is the clinically significant genetic alterations in each disease type. Use [https://www.genenames.org/ <u>HUGO-approved gene names and symbols</u>] (italicized when appropriate), [https://varnomen.hgvs.org/ HGVS-based nomenclature for variants], as well as generic names of drugs and testing platforms or assays if applicable. Please complete tables whenever possible and do not delete them (add N/A if not applicable in the table and delete the examples). Please do not delete or alter the section headings. The use of bullet points alongside short blocks of text rather than only large paragraphs is encouraged. Additional instructions below in italicized blue text should not be included in the final page content.

*Lymphoplasmacytic lymphoma (LPL) is a neoplasm of small B lymphocytes, plasmacytoid lymphocytes, and plasma cells, usually involving bone marrow and spleen, which does not fulfil the criteria for any of the other small B-cell lymphoid neoplasms, that can have plasmacytic differentiation. <ref name=":0" />

*Rare involvement of CNS associated with Waldenström macroglobulinemia (known as [[Bing-Neel syndrome]]). Lymphoplasmacytic lymphoma may occur at sites typically involved by extranodal marginal zone lymphoma (MZL) of mucosal-associated lymphoid tissue (MALT lymphoma), such as the ocular adnexa. <ref name=":0" /><ref name=":1" />
