Overview

Genes involved in the pathogenesis of splenic marginal zone lymphoma include immunoglobulin genes and CDK6 gene. On microscopic histopathological analysis, B-cells, villous lymphocytes, and sinus invasion are characteristic findings of splenic marginal zone lymphoma.

Pathophysiology

Pathogenesis

Genetics

  • Clonal rearrangements of the immunoglobulin genes (heavy and light chains) [1]
  • Most common chromosomal abnormality seen in splenic marginal zone lymphoma is the deletion of 7q region.[2]
  • Other abnormalities such as gain of function mutation in 3q, 4q, 5q, 9q, 12q, 20q and loss of function mutations in 7q and 17p have also been found.[3][4][5]
  • Most common genetic mutation is of NOTCH2 gene.[6][7]
  • Other genes involved with decreasing frequency are KLF2, CARD1, TRAF3, MYD88,TP53.[8][9][10][11][12]
  • Translocations of the CDK6 gene located at 7q21 have also been reported[13]
  • There are several pathways involved in the normal functioning of the cells. Genetic dysregulation may affect these pathways resulting in abnormal function.
  • Common genetic abnormalities and their affected pathways in splenic marginal zone lymphoma are summarized under:
Pathways Gene mutations

NFkB[14][15][9]

Apoptosis[16][17]

Cell communication[18][19][20]

Cell cycle control[5][17][20]

Lymphocyte development and regulation[18][15][20]

Chromosomal and transcriptional regulation[15][21]

Associated conditions

  • Hepatitis C infection
    • A strong association between splenic marginal zone lymphoma (SMZL) and hepatitis C infection has been observed in several studies indicating that viral antigen may be involved in the pathogenesis of the lymphoma.[22][23]
    • It is assumed that may be the HCV antigen stimulate the monoclonal B-cell proliferation through their specific receptor on the cell surface.[24][25]
    • Regression of the lymphoma was seen in patients after treatment with anti viral therapy again suggesting the role of viral antigen in its pathogenesis.[26]

Immunophenotype

Gross and Microscopic Pathology

  • Splenic marginal zone lymphoma (SMZL) is a subtype of non-hodgkin's lymphoma comprised of B-cells.[33]
  • It tends to involve spleen, bone marrow, liver and blood.[34]
  • The microscopic features of these organs are described below:
  • Spleen
    • Nodular pattern of lymphocytic infiltration of the white pulp involving both mantle ad marginal zone component.[27]
    • Biphasic distribution of B cell lymphocytes i.e small cells having dense chromatin and scant cytoplasm surrounded by intermediate size cells with interspersed blast cells.
    • Red pulp may also be involved either sparingly or diffusely penetrating the sinuses and cords.[35]
  • Bone Marrow:
    • Various patterns of Lymphocytic infiltration such as intrasinusoidal, nodular, interstitial and intravascular have been observed.[36]
    • Mixed pattern of lymphocytic infiltration with intrasinusoidal being predominant.[37][38]
    • Cell population consists of small, intermediate and large lymphoid cells but small cells having large nucleus with dense chromatin and scant cytoplasm are present in abundance.[39]
  • Lymph nodes
    • Splenic hilar and peripheral lymph nodes may be involved but less frequently as compared to the other organs.
    • Micronodular infiltration with no involvement of the sinuses.[40]


  • Blood
