The exact pathogenesis of [[splenic marginal zone lymphoma]] ([[SMZL]]) is not clearly understood but according to some studies chronic immunologic stimulation and certain [[gene]] [[mutations]] are assumed to be involved. The common [[chromosomal]] aberrations and genetic mutations in [[splenic marginal zone lymphoma]] ([[SMZL]]) includes 7q32 deletion, gain of function [[mutation]] in 3q and [[NOTCH2]], [[TP53]], [[KLF2]] [[gene]] [[mutations]]. These [[genes]] control certain [[cell regulation]] pathways that are involved in normal functioning of the cell. [[Hepatitis C]] viral antigen has also been assumed to be involved in its pathogenesis. [[Spleen]], [[bone marrow]], [[lymph nodes]], liver and [[blood]] may be infiltrated with the tumor and have certain distintive features. On microscopic histopathological analysis, [[B-cells]], villous [[lymphocytes]], and [[sinus]] invasion are characteristic findings of [[splenic marginal zone lymphoma]] ([[SMZL]]). | |||

Overview
The exact pathogenesis of splenic marginal zone lymphoma (SMZL) is not clearly understood but according to some studies chronic immunologic stimulation and certain gene mutations are assumed to be involved. The common chromosomal aberrations and genetic mutations in splenic marginal zone lymphoma (SMZL) includes 7q32 deletion, gain of function mutation in 3q and NOTCH2, TP53, KLF2 gene mutations. These genes control certain cell regulation pathways that are involved in normal functioning of the cell. Hepatitis C viral antigen has also been assumed to be involved in its pathogenesis. Spleen, bone marrow, lymph nodes, liver and blood may be infiltrated with the tumor and have certain distintive features. On microscopic histopathological analysis, B-cells, villous lymphocytes, and sinus invasion are characteristic findings of splenic marginal zone lymphoma (SMZL).
Pathophysiology
Pathogenesis
- Several studies suggest that both chronic immunologic stimulation and gained genetic mutations play a role in the pathogenesis of splenic marginal zone lymphoma (SMZL) but the exact mechanism is still not clear.[1][2]
- There has been data to suggest that splenic marginal zone lymphoma (SMZL) can either originate from pre-germinal center B-cells or germinal or post-germinal center B cells based on immunoglobulin heavy chain gene mutation.[3][4][5][6][7][8]
- Normal splenic marginal zone appears to be composed of both naïve and memory B-cells which actually support the idea of having different cell origin.[9][10]
Genetics
- Clonal rearrangements of the immunoglobulin genes (heavy and light chains) [11]
- Most common chromosomal abnormality seen in splenic marginal zone lymphoma is the deletion of 7q region.[12]
- 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.[13][14][15]
- Most common genetic mutation is of NOTCH2 gene.[16][17]
- Other genes involved with decreasing frequency are KLF2, CARD1, TRAF3, MYD88,TP53.[18][19][20][21][22]
- Translocations of the CDK6 gene located at 7q21 have also been reported[23]
- 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 |
---|---|
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.[32][33]
- It is assumed that may be the HCV antigen stimulate the monoclonal B-cell proliferation through their specific receptor on the cell surface.[34][35]
- Regression of the lymphoma was seen in patients after treatment with anti viral therapy again suggesting the role of viral antigen in its pathogenesis.[36]
Microscopic Pathology
- Splenic marginal zone lymphoma (SMZL) tends to involve different organs such as spleen, bone marrow, blood and lymph nodes.[37].[38]
- The microscopic features of these organs are described below:
Spleen
- Micronodular pattern of lymphocytic infiltration of the white pulp involving both mantle and marginal zone component.[39]
- Biphasic distribution of neoplastic B-cell in the follicles i.e small cells having dense chromatin and scant cytoplasm surrounded by intermediate size cells of marginal zone having variable nuclear contour and relatively abundant cytoplasm with interspersed large B-cells.
- Red pulp may also be involved either sparingly or diffusely penetrating the sinuses and cords.[40]
Bone Marrow:
- Various patterns of Lymphocytic infiltration such as intrasinusoidal, nodular, interstitial and intravascular have been observed.[41]
- Mixed pattern of lymphocytic infiltration with intrasinusoidal being predominant.[42][43]
- 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.[44]
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.[45]
Blood
- Unusual neoplastic lymphoid B-cells with irregular cytoplasmic processes.[46]
