Overview
Splenic marginal zone lymphoma (SMZL) is rare, indolent B-cell lymphoma that may arise from either pre germinal or germinal/post germinal center replacing the normal architecture of the white pulp of the spleen. Chromosomal aberrations and gene mutations involved in the pathogenesis of splenic marginal zone lymphoma include 7q32 deletion, gain of function 3q, 4q and NOTCH2, TP53, KLF2 and immunoglobulin heavy chain gene. On microscopic histopathological analysis, micronodular lymphocytic infiltration of the white pulp along with biphasic distribution of neoplastic B-cells in the follicles of spleen, mixed pattern of lymphocytic infiltration of the bone marrow and villous lymphocytes in peripheral blood, are the characteristic findings of splenic marginal zone lymphoma (SMZL). Hepatitis C viral antigen is also assumed to be involved in its causation. Splenic marginal zone lymphoma (SMZL) must be differentiated from other B-cell lymphomas such as chronic lymphocytic leukemia, follicular lymphoma, and mantle cell lymphoma and unclassifiable splenic lymphomas including hairy cell leukemia variant (HCL-v) and splenic diffuse red pulp small B-cell lymphoma (SDRPL). The incidence of splenic marginal zone lymphoma (SMZL) increases with age; the median age at diagnosis is 65-70 years. Splenic marginal zone lymphoma (SMZL) affects men and women equally. There are no established risk factors. According to the the U.S. Preventive Service Task Force (USPSTF), there is insufficient evidence to recommend routine screening. Low Hemoglobin levels, high lactate dehydrogenase levels, low blood serum albumin levels, and genetic mutations in NOTCH2 TP53 genes are associated with poor prognosis. According to the Lugano classification, there are four stages of splenic marginal zone lymphoma (SMZL) based on the number of nodes and extranodal involvement. The most common symptoms of splenic marginal zone lymphoma include fever, weight loss, skin rash, night sweats, chest pain, abdominal pain, bone pain, and painless swelling in the neck, axilla, groin, thorax, and abdomen. Common physical examination findings of splenic marginal zone lymphoma (SMZL) include fever, rash, ulcer, splenomegaly, chest tenderness, abdomen tenderness, bone tenderness, peripheral lymphadenopathy, and central lymphadenopathy. Laboratory tests for splenic marginal zone lymphoma (SMZL) include complete blood count (CBC), blood chemistry studies, cytogenetic analysis, flow cytometry, immunohistochemistry, genetic testing, FISH, PCR, and immunophenotyping. Lymph node or extranodal tissue( spleen, bone marrow) biopsy is diagnostic of splenic marginal zone lymphoma.splenomegaly and lymphadenopathy and other organs involvement may be seen on abdominal ultrasound, CT scan, MRI and PET scan in patients with splenic marginal zone lymphoma (SMZL). Other diagnostic studies include laparoscopy, laparotomy. The optimal therapy for splenic marginal zone lymphoma (SMZL) depends on the clinical presentation of the patient. Asymptomatic patients may be observed closely without any treatment. Splenomegaly related symptoms such as abdominal distension, tenderness, early satiety, bloating and cytopenia due to hypersplenism may be managed with splenectomy but if bone marrow is involved it will persist even after surgery. Splenectomy was considered to be the first line treatment option but studies reported recently that rituximab alone or in combination with chemotherapy is equally effective if not better in terms of complete remission, progression free and overall survival and in addition there is no surgical risk. Studies have also shown that patients who relapsed while on treatment with rituximab, responded well with retreatment. Patients with hepatitis C who developed splenic marginal zone lymphoma (SMZL) have shown tumor regression with antiviral therapy.
Historical Perspective
The term splenic marginal zone lymphoma (SMZL) was used by C. Schmid in 1992 and is described as separate entity from marginal zone lymphoma in the World Health Organization classification of lymphoid neoplasms in 2001.
Pathophysiology
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).
Causes
Some studies suggest an association between Hepatitis C and splenic marginal zone lymphoma (SMZL) and assume that it may have some role in its causation.
Differential Diagnosis
Splenic marginal zone lymphoma (SMZL) must be differentiated from other B-cell lymphomas such as chronic lymphocytic leukemia, follicular lymphoma, mantle cell lymphoma and unclassifiable B-cell lymphomas including Hairy cell leukemia variant (HCL-v) and splenic diffuse red pulp small B-cell lymphoma (SDRPL) on the basis of cytogenetics, immunophenotyping and morphological as the treatment for these conditions varies.
Epidemiology and demographics
Splenic marginal zone lymphoma (SMZL) constitutes less than 1% of all non-Hodgkin’s lymphomas. Its incidence increases with age. It is found to be more common in caucasians. Splenic marginal zone lymphoma (SMZL) affects men and women equally.
Risk Factors
There are no established risk factors for splenic marginal zone lymphoma.
Screening
According to the the U.S. Preventive Service Task Force (USPSTF), there is insufficient evidence to recommend routine screening for splenic marginal zone lymphoma
Natural History, Complications and Prognosis
Splenic marginal zone lymphoma (SMZL) is a rare, slow growing B-cell lymphoma that is mostly asymptomatic at the time of diagnosis. It is commonly diagnosed at an old age. Patients typically have splenomegaly, lymphocytosis or cytopenias. Bone marrow is frequently involved but lymphadenopathy and liver involvement is rare.There are automimmune conditions that may develop in this conditions such autoimmune hemolytic anemia, idiopathic thrombocytopenic purpura, angioedema and von-willebrand disease. It may transform into diffuse large B-cell lymphoma. The prognosis is generally good. Several factors including lymphadenopathy, non-hematopoietic site involvement, histologic transformation affects the prognosis. Low Hemoglobin levels, high lactate dehydrogenase levels, low blood serum albumin levels, and genetic mutations such as mutations in NOTCH2, TP53, KLF2 are associated with poor prognosis among patients with splenic marginal zone lymphoma.
Diagnosis
Diagnostic Study of Choice
Histological examination of the spleen is considered as a gold standard for the diagnosis of splenic marginal zone lymphoma (SMZL). But as splenectomy is not as frequently performed as it was other diagnostic options are sought which includes histological analysis and immunohistochemistry of the bone marrow biopsy and peripheral blood. Cytogenetic analysis is also helpful in making the diagnosis.
Staging
According to the Lugano classification, there are four stages of splenic marginal zone lymphoma (SMZL) based on the number of nodes and extranodal involvement.
History and Symptoms
The most common symptoms of splenic marginal zone lymphoma (SMZL) include fever, weight loss, skin rash, night sweats, chest pain, abdominal pain, bone pain, and painless swelling in the neck, axilla, groin, thorax, and abdomen.
Physical Examination
Common physical examination findings of splenic marginal zone lymphoma (SMZL) include fever, rash, ulcer, splenomegaly, chest tenderness, abdomen tenderness, bone tenderness, peripheral lymphadenopathy, and central lymphadenopathy.
Laboratory tests
Laboratory tests for splenic marginal zone lymphoma (SMZL) include complete blood count (CBC), blood chemistry studies, immunohistochemistry, genetic testing, flow cytometry, FISH, PCR, and immunophenotyping.
Biopsy
Lymph node or extranodal tissue biopsy is diagnostic of splenic marginal zone lymphoma (SMZL).
CT
CT scan may be helpful in the diagnosis and estimating the extent of tumor spread in splenic marginal zone lymphoma (SMZL).
MRI
MRI may be helpful in the diagnosis of splenic marginal zone lymphoma (SMZL).
Ultrasound
Abdomen ultrasound may be helpful in the diagnosis of splenic marginal zone lymphoma (SMZL). Findings on ultrasound abdomen suggestive of splenic marginal zone lymphoma (SMZL) include splenomegaly and lymphadenopathy.
Other Imaging Studies
PET scan may be helpful in the diagnosis of splenic marginal zone lymphoma (SMZL).
Other Diagnostic Studies
Other diagnostic studies for splenic marginal zone lymphoma (SMZL) include laparoscopy and laparotomy.
Treatment
Medical Therapy
There is no standardized treatment of splenic marginal zone lymphoma (SMZL) The optimal therapy depends on the clinical presentation. Asymptomatic patients may only be observed routinely without any treatment as it is an indolent tumor. Symptomatic patients may treated with either surgery, immunotherapy, chemotherapy, immunochemotherapy or antiviral drugs. Both surgery and immunotherapy are equally effective but recently immunotherapy is considered as a better treatment option as there is no risk of complications that are associated with surgery.
Surgery
Splenectomy was considered to be the 1st line treatment option for splenic marginal zone lymphoma (SMZL) but recent studies have shown that rituximab is equally effective if not better treatment option in terms of overall survival. Splenectomy is still performed but mainly in patients with splenomegaly without lymphadenopathy having low surgical risk or in those who are refractory to rituximab therapy.

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]

Overview
Some studies suggest an association between Hepatitis C and splenic marginal zone lymphoma (SMZL) and assume that it may have some role in its causation.
Causes
- An association between splenic marginal zone lymphoma and hepatitis C infection has been observed so its is assumed that it may have some role in its causation.[1]

Differentiating Splenic marginal zone lymphoma from other Diseases

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Muhammad Affan M.D.[2], Sowminya Arikapudi, M.B,B.S. [3]
Overview
Splenic marginal zone lymphoma (SMZL) must be differentiated from other B-cell lymphomas such as chronic lymphocytic leukemia, follicular lymphoma, mantle cell lymphoma and unclassifiable B-cell lymphomas including Hairy cell leukemia variant (HCL-v) and splenic diffuse red pulp small B-cell lymphoma (SDRPL) on the basis of cytogenetics, immunophenotyping and morphological as the treatment for these conditions varies.
Differential Diagnosis
Splenic marginal zone lymphoma(SMZL) must be differentiated from other splenic B-cell lymphomas with the help of clincal, morphological, immunophenotypic and genetic data as the treatment of all these conditions are different from each other.[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][22][27][28]

Overview
Splenic marginal zone lymphoma (SMZL) constitutes less than 1% of all non-Hodgkin’s lymphomas. Its incidence increases with age. It is found to be more common in caucasians. Splenic marginal zone lymphoma (SMZL) affects men and women equally.
Epidemiology and demographics
Incidence
- Splenic marginal zone lymphoma represents less than 1% of all non-hodgkins lymphomas.[1][2]
- It constitutes around 20% of all marginal zone lymphomas (MZL).[3]
- The overall annual age adjusted incidence during 2001-2008 was 0.13/100,000 person per year that seems to gradually increasing with time.[4][5]
Age
- The incidence of splenic marginal zone lymphoma increases with age
- The median age at the time of diagnosis is 69 years.[6]
Race
- Splenic marginal zone lymphoma is more common in the white patient population..[2]
Gender
Splenic marginal zone lymphoma affects men and women equally.[7]

Overview
Splenic marginal zone lymphoma (SMZL) is a rare, slow growing B-cell lymphoma that is mostly asymptomatic at the time of diagnosis. It is commonly diagnosed at an old age. Patients typically have splenomegaly, lymphocytosis or cytopenias. Bone marrow is frequently involved but lymphadenopathy and liver involvement is rare.There are automimmune conditions that may develop in this conditions such autoimmune hemolytic anemia, idiopathic thrombocytopenic purpura, angioedema and von-willebrand disease. It may transform into diffuse large B-cell lymphoma. The prognosis is generally good. Several factors including lymphadenopathy, non-hematopoietic site involvement, histologic transformation affects the prognosis. Low Hemoglobin levels, high lactate dehydrogenase levels, low blood serum albumin levels, and genetic mutations such as mutations in NOTCH2, TP53, KLF2 are associated with poor prognosis among patients with splenic marginal zone lymphoma.
Natural history
- Splenic marginal zone lymphoma (SMZL) is an uncommon B-cell lymphoma having an indolent course.[1]
- The median age of diagnosis is 65-70 years.[2]
- Majority of the patients are asymptomatic at the time of diagnosis but when symptomatic it may present with symptoms related to splenomegaly such as early satiety, abdominal discomfort, and cytopenias such as bleeding.[3]
- systemic B symptoms such as fatigue, night sweats and weight loss are uncommon.
- Patients typically have splenomegaly, cytopenias or lymphocytosis but lymphadenopathy is rare.[4]
- Prognosis is favorable with median overall survival around 8-12 years.[5]
- Rarely, it becomes aggressive and having median overall survival of less than 2 years.[6]
Complications
- Large B-cell lymphoma[7][8]
- Autoimmune complications such as:[9][10]
- Autoimmune hemolytic anemia
- Immune thrombocytopenic purpura (ITP)
- Lupus anticoagulant
- C1-esterase inhibitor deficiency
- Acquired von Willebrand disease
Prognosis
- Splenic marginal zone lymphoma (SMZL) is an indolent tumor with median overall survival of 8-12 years.[11][12]
- Several factors affects the prognosis in splenic marginal zone lymphoma (SMZL) including
- Lymphadenopathy
- Increase in b2 microglobulin
- Lymphocytosis, Leukocytosis, Lymphopenia, Anemia, Thrombocytopenia[13]
- Use of chemotherapy[14]
- Monoclonal component[15]
- Non-hematopoietic site involvement[6]
- Histologic transformation[16]
- Advanced age[17][18]
- Diffuse pattern of bone marrow involvement[13]
- Incomplete response[6]
- A SMZL Study Group prognostic index (SMZLSG) using HPLL stratifiction system was devised to determine 5 year lymphoma specific survival (LSS) using variables such as hemoglobin, platelet count, lactate dehydrogenase (LDH), lymphadenopathy indicating their importance in predicting the prognosis.[19]
- The system was further modified as HPLL/ABC (A= low risk, B= intermediate risk, C= high risk) to make it clinically useful.[20]
- Another prognostic index named as the Intergruppo Italiano Linfomi (IIL) determined the 5 year cause specific survival using three variables, with their presence predicitng worse outcome.
- Hemoglobin <12g/dl
- Serum lactate dehydrogenase (LDH) level greater than normal
- Serum albumin < 3.5g/dl
- Genetic mutations such as TP53, NOTCH2, KLF2 are associated with poor outcomes.[21][17][22][23]
- Presence of autoimmune hemolytic anemia (AIHA) in splenic marginal zone lymphoma (SMZL) patients has also been reported to be associated with poor prognosis.[24]
