(General Instructions – The main focus of these pages is the clinically significant genetic alterations in each disease type. Use HUGO-approved gene names and symbols (italicized when appropriate), 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.

Definition / Description of Disease

  • Paediatric nodal marginal zone lymphoma (pNMZL) is a rare and distinct entity of NMZL seen in the pediatrics and young adult population[1]
  • pNMZL typically presents with an indolent course and localized disease[1], contrary from classic NMZL seen in adults[2]
  • Typically presents as asymptomatic, localized lymphadenopathy (Stage I)[3][4][5]
  • Laboratory testing: normal serum lactate dehydrogenase (LDH) levels[3][4][5]
  • Prognosis is typically excellent[4][5][6]
    • Five year event free survival: 94±6%[4]
    • Five year overall survival: 100%[4]
  • Complete remission follows surgical resection in most patients with limited/localized disease[4][7]
  • Chemotherapy and radiation therapy have also been used for management of limited stage disease[4][7]

Synonyms / Terminology

  • Monocytoid B-cell lymphoma
  • Parafollicular B-cell lymphoma (obsolete)

The content below was from the old template. Please incorporate above.

Sites of Involvement

Morphologic Features

  • Effacement of lymph node architecture due to expansion of marginal zone and intrafollicular proliferation
    • Expanded marginal zone may be delineated by IgD staining[6][7]
  • Follicular hyperplasia with features of progressive transformation of germinal centers (PTGC)[3][6][7][9]
  • Polymorphic infiltrate composed of small- to medium-sized cells with round nuclei and moderate cytoplasm[3][7]
  • Starry-sky appearance of residual hyperplastic germinal centers[9]

Immunophenotype

  • Similar to adult-type NMZL, pNMZL is almost universally positive for the mature B cell marker CD20 (90-100%) with most cases also expressing the pan-T cell marker CD43 (70-100%)[3][6][7][9][14]
  • A subset of pNMZL express BCL2 (40-50%) and IgD (20-30%)[3][6][7]
  • pNMZL cells are negative for the germinal center markers CD10, BCL6, CD23, and the T cell markers CD3, CD5[3][6][7][10]
  • CD279/PD-1 staining present in reactive germinal centers of pNMZL, compared to positive staining at the periphery of germinal centers in nodal pediatric-type follicular lymphoma[9]
Finding Marker
Positive (universal) CD19, CD20, sIg (bright, monoclonal), CD43
Positive (subset) BCL2, CD279/PD-1, IgD
Negative (universal) CD10, BCL6, CD23, CD5, CD3, LEF1
