Cancer Category/Type

Cancer Sub-Classification / Subtype

  • Nodal Marginal Zone Lymphoma

Definition / Description of Disease

Nodal marginal zone lymphoma (NMZL) is an uncommon subtype of non-Hodgkin lymphoma. It is a primary nodal B-cell lymphoma with histological features similar to Splenic marginal zone lymphoma and Extranodal marginal zone lymphoma involving lymph nodes, but without evidence of splenic or extranodal disease[1].

Synonyms / Terminology

  • Monocytoid B-cell lymphoma
  • Parafollicular B-cell lymphoma (no longer in use)

Epidemiology / Prevalence

  • 1.5-1.8% of all lymphoid neoplasms
  • Median age ~60 years old
  • Both sexes are affected equally
  • Cases also occur in children and are separately diagnosed as Paediatric Nodal Marginal Zone Lymphoma
  • Association with autoimmune diseases
  • Association with Hepatitis C virus infection reported in some studies but not all studies

Clinical Features

Put your text here and fill in the table (Instruction: Can include references in the table)

Signs and Symptoms EXAMPLE Asymptomatic (incidental finding on complete blood counts)

EXAMPLE B-symptoms (weight loss, fever, night sweats)

EXAMPLE Fatigue

EXAMPLE Lymphadenopathy (uncommon)

Laboratory Findings EXAMPLE Cytopenias

EXAMPLE Lymphocytosis (low level)


editv4:Clinical Features
The content below was from the old template. Please incorporate above.
  • Asymptomatic, localized or generalized lymphadenopathy
  • B symptoms (fever, night sweats, and weight loss)
  • Bone marrow involvement

The presence of a primary extranodal marginal zone lymphoma should be ruled out due to the possibility of a nodal dissemination of a MALT lymphoma occurring in patients with a history of Sjogren syndrome and Hashimoto thyroiditis[1].

Sites of Involvement

  • Lymph nodes
  • Bone marrow
  • Peripheral blood

Morphologic Features

  • Variable populations of lymphoma cells
    1. Centrocyte-like and monocytoid B-cells
    2. Plasma cells
    3. Scattered transformed B cells
  • Lymph nodes show small lymphoma cells surrounding reactive follicles (marginal zone distribution)
    1. Extension to interfollicular areas and follicular colonization may be present
    2. Diffuse or partial nodal effacement may be present
  • Bone marrow shows lymphoma cells in interstitial, nodular, intertrabecular or paratrabecular distribution

editv4:Gene Mutations (SNV/INDEL)
The content below was from the old template. Please incorporate above.

Whole-exome sequencing (WES) study have identified mutations involved in NOTCH, nuclear factor κB (NF-κB), B-cell receptors and toll like receptor pathways . In one study, 16% (4/25) of cases identified a BRAF (V600E) mutation with associated strong IgD expression. In one of the four BRAF positive mutation, two non-hotspot mutations were detected (L597Q and N581I) which was previously found in BRAF V600 wild-type melanoma. In the same study, mutations of KMT2D (7/25, 28%), TET2 (5/25, 20%), and EZH2 (5/25, 20%) were among the more frequent mutated genes. CREBBP, TNFRSF14, FAS, TNFAIP3, KLF2, and CXCR4 mutations were also detected[4]. In another study, which investigated genetic lesions in 35 patients with NMZL, PTPRD mutations were found in 14.3% (5/35) of patients and PTPRD locus deletions were found in 5.7% (2/35) of patients[5]. Mutations were also identified in another study for NFKBIE and ITPR2 mutations involved in the NF-κB pathway and B-cell receptor mediated calcium signal pathway. However, in this study they did not find any PTPRD mutations or BRAF mutations, demonstrating the diverseness of the disease[6]. No BRAF mutations have yet to be identified in other studies on NMZL[4].

Other Mutations

Immunoglobulin genes are clonally rearranged consisting of mutated IGHV3 and IGHV4 family members, particularly IGHV4-34 and cases associated with hepatitis C use IGHV1-69[1].
