Splenic marginal zone lymphoma (SMZL) is a rare, indolent non-Hodgkin's lymphoma that affects 0. 13 per 100,000 persons annually. Overall survival of SMZL is estimated to reach 8-11 years in most cases, but up to 30% of SMZL cases develop aggressive presentations resulting in greatly diminished time of survival They are followed by splenic marginal zone lymphoma (SMZL), which represents roughly 20% of cases, and by nodal MZL (NMZL), the most infrequently occurring entity. 1,2 Given their rarity, it is often difficult to conduct clinical trials specifically designed for patients with MZL Nodale marginale zone lymfomen ontstaan in een lymfeklier, het splenisch marginaal zone lymfoom ontstaat in de milt.

1 Introduction. Aggressive variant of splenic marginal zone lymphoma (AV-SMZL) is a rare disorder. Although little is known about its pathogenesis or clinical characteristics, earlier studies reported that AV-SMZL is associated with an increase in large abnormal lymphocytes, withTP53 mutations, and with an aggressive disease course and poor prognosis Marginal zone lymphomas (MZL) are distinct B cell neoplasms with variable clinical presentations. The clinicopathologic entities include (1) extranodal marginal zone MALT lymphoma, (2) nodal marginal zone lymphoma (MZL), and (3) splenic marginal zone lymphoma (MZL) Splenic marginal zone lymphoma is a type of cancer made up of B-cells that replace the normal architecture of the white pulp of the spleen. The neoplastic cells are both small lymphocytes and larger, transformed lymphoblasts, and they invade the mantle zone of splenic follicles and erode the marginal zone, ultimately invading the red pulp of the spleen. Frequently, the bone marrow and splenic hilar lymph nodes are involved along with the peripheral blood. The neoplastic cells circulating in th Splenic marginal zone lymphoma (splenic MZL) is rare. It accounts for fewer than 2 in every 100 cases of non-Hodgkin lymphoma. Splenic MZL can affect people of any age but it is most common in people in their 60s. In most cases, it is not known wha Primary splenic lymphoma is a rare type of malignant lymphoma, which involves only the spleen and splenic hilar lymph nodes. However, splenic marginal zone lymphoma (SMZL) is even rarer. SMZL represents a rare chronic B lymphocyte proliferative disease, which only accounts for about 1-2% of non-Hodgkin's lymphoma [ 1 ]
Splenic Marginal Zone Lymphoma (SMZL) is an Unusual, distinct lymphoma characterized by indolent clinical course and prolonged survival, and having some clinical, cellular and immunophenotypical features that differ from other indolent lymphomas. We describe a case of SMZL that presented with autoimmune hemolytic anemia The lymphoma cells are positive for IgD (pictured on the left). Most marginal zone lymphoma of splenic origin (as compared to nodal marginal zone lymphoma) are more likely to be positive for IgD. CD21 immunostain (pictured on the right) highlights markedly expanded and tight follicular dendritic cell meshworks within the lymphoma nodules Microscopic (histologic) description. Marginal zone, biphasic or diffuse red pulp variants (see note) Massive splenic involvement, with infiltration of small atypical lymphocytes in mantle zone and medium lymphocytes with pale cytoplasm and oval clear nucleus in marginal zone, leading to mixed mantle zone and marginal zone involvement pattern Splenisch marginale zone lymfoom is een zeldzaam, indolent B-cel non-Hodgkinlymfoom dat wordt gekarakteriseerd door abnormale klonale proliferatie van rijpe B-lymfocyten in de milt, het beenmerg en, frequent, het bloed. De ziekte manifesteert zich meestal met splenomegalie, lymfocytose, anemie en/of trombocytopenie

My knowledge of splenic marginal zone lymphoma is a bit limited, but I am understanding that it is a type of B-cell lymphoma that affects the spleen. We do have some members talking about B-cell lymphoma, and while they may not be in the exact same situation as yourself, they may be able to provide some incite and experiences to share with a bone biopsy and the waiting for results Splenic lymphoma, also termed as lymphomatous involvement of the spleen, represents the most common malignancy to involve the spleen. They are commonly secondary, rarely being primary (referred as primary splenic lymphoma)

According to the different cell sources, it is divided into non-Hodgkin lymphoma (NHL) and Hodgkin lymphoma (HL). Primary splenic lymphoma is a rare type of malignant lymphoma. Splenic marginal zone B-cell lymphoma is a rare form of MZL, accounting for less than 2% of lymphomas, according to the American Society of Hematology's Blood Journal. It develops in the spleen, bone marrow, or both. Symptoms of Marginal Zone Lymphoma. The symptoms of MZL vary depending on the type. These symptoms occur in most types of MZL

Background. Splenic marginal zone lymphoma (SMZL) is a newly acknowledged cancer that effects primarily middle-aged and elderly patients. This disease primarily effects patients ages 60 and older without evidence of gender predominance ().Since SMZL is less than a quarter-century old in terms of recognition by the World Health Organization, little progress has been made regarding disease. Marginal zone lymphoma (MZL) is a slow growing type of non-Hodgkin lymphoma (NHL). Often seen more in women than in men, the average age of diagnosed patients is 60 years old. Marginal zone lymphoma accounts for about 8% of all non-Hodgkin lymphoma cases. It is differentiated between 3 similar subgroups depending on chromosomal, genetics and immunophenotypes Marginal zone lymphoma is an uncommon type of non-Hodgkin's lymphoma, and renal involvement is rare. This case highlights the importance of considering alternative diagnoses when there is deviation from the expected clinical trajectory and the importance of liaising with colleagues in other disciplines to enable an accurate diagnosis to be made
Despite being the second most common indolent non-Hodgkin's lymphoma (iNHL), marginal zone lymphoma (MZL) remains largely understudied, and given its underlying disease heterogeneity, it is challenging to define a single treatment approach for these patients Splenic marginal zone lymphoma (SMZL), along with extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) and nodal marginal zone lymphoma (NMZL), share a common origin from the marginal zone. However, these three entities display different clinical characteristics,. Splenic marginal zone lymphoma demonstrates various patterns of infiltration in the bone marrow, typically with a nodular, interstitial, and intrasinusoidal distribution. 7 An anti-CD20 stain highlighting a mixed pattern of bone marrow involvement in a case of SMZL is shown in Figure 2, A Splenic Marginal Zone Lymphoma (SMZL) Definition / Description of Disease.

On the other hand, recent advances in genome sequencing techniques enable us to understand the molecular characteristics of rare cancers such as AV-SMZL Splenic marginal zone lymphoma (SMZL) is primarily located in the spleen and invariably involves the bone marrow.

The marginal zone is the region at the interface between the non-lymphoid red pulp and the lymphoid white-pulp of the spleen. (Some sources consider it to be the part of red pulp which borders on the white pulp, while other sources consider it to be neither red pulp nor white pulp. The term splenic marginal zone lymphoma (SMZL) was initially proposed by Schmid and Isaacson in 1992 (Schmid et al. 1992) for describing a B-cell lymphoma involving the spleen with a micronodular infiltration pattern and a peculiar morphology suggesting marginal zone origin.The splenic histology and peripheral blood features in these cases was overlapping with those found in the condition.

Splenic marginal zone lymphoma is a small B-cell neoplasm whose molecular pathogenesis is still essentially unknown and whose differentiation from other small B-cell lymphomas is hampered by the lack of specific markers. We have analyzed the gene expression and miRNA profiles of 31 splenic marginal The diagnosis of marginal zone lymphoma (MZL) is frequently challenging and, in some cases, remains one of exclusion. 1-5 MZL is cytologically heterogeneous, with cases showing varying proportions of monocytoid cells, marginal zone-type cells, small lymphocytes, and plasma cells. 6, 7 Architecturally, MZL may show a diffuse growth pattern or contain varying numbers of follicular structures. Splenic lymphoma, also termed as lymphomatous involvement of the spleen, represents the most common malignancy to involve the spleen.They are commonly secondary, rarely being primary (referred as primary splenic lymphoma)..
