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)
editUnassigned ReferencesThe following referenees were placed in the header. Please place them into the appropriate locations in the text.
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 HAEM5: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 FeaturesThe 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
- Centrocyte-like and monocytoid B-cells
- Plasma cells
- Scattered transformed B cells
- Lymph nodes show small lymphoma cells surrounding reactive follicles (marginal zone distribution)
- Extension to interfollicular areas and follicular colonization may be present
- 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].
