Abstract
Splenic marginal zone lymphoma (SMZL) is a low-grade mature B-cell lymphoma that typically presents in the form of splenomegaly and lymphocytosis. The diagnosis is traditionally made through splenic histology, the presence of circulating villous lymphocytes, or bone marrow biopsy. Its treatment can be in the form of chemotherapy, such as rituximab, or active surveillance. This case presentation discusses a 76-year-old female with a long history of hydroxyurea use for an unknown reason presenting with atypical symptoms requiring bone marrow biopsy to diagnose SMZL. This unique case demonstrates the importance of further research and studies into atypical SMZL presentations and hydroxyurea's potential in precipitating secondary malignancies.

Abstract
Treatment of indolent lymphoma has improved significantly in recent decades since the advent of rituximab (anti-CD20 monoclonal antibody). Although, some patients with limited disease can be cured with radiation therapy alone, most patients experience disease progression and recurrence during follow-up despite early initiation of treatment. Thus, watch-and-wait is still regarded the standard for asymptomatic patients. Patients with indolent lymphoma have a significant heterogeneity in terms of tumor burden, symptoms (according to anatomical sites) and the need for instant therapy. Therefore, the initiation of treatment and treatment option should be decided with a clear goal in each patient according to the need for therapy and clinical benefits with the chosen treatment. In this review, we cover the current treatment of follicular lymphoma and marginal zone lymphoma.

Abstract
Splenic marginal zone lymphoma (SMZL) is a rare lymphoproliferative disease involving B-cells and affecting elderly patients. SMZL plague peripheral blood and bone marrow, spleen. Lymph nodes are generally spared. SMZL is due to a protracted antigen stimulation of B lymphocytes and of microenvironment leading B-cell to polyclonal and then oligoclonal/monoclonal growth, promoting lymphoproliferation. Integration of the NOTCH2 and NFk-B signaling has been recently identified as the primary mechanism of neoplastic proliferation in SMZL. In total 20% of cases carry mutations in NOTCH2. Although SMZL has an indolent course, progression to diffuse large B-cell lymphoma occurs in about 10-15% of patients. Establishing the prognosis is a key step in disease management, depending on both individual risk and patients' health status. This review discusses tailored treatment of SMZL patients. Progression risk factors include nodal and extra-nodal involvement, peripheral lymphocytosis, anemia and thrombocytopenia. Patients with two or more score points have a median survival of <5 years. Watch and wait strategy is appropriate in low-risk and asymptomatic patients, whereas treatment of symptomatic patients ranges from splenectomy to rituximab monotherapy or associated with chemotherapy.

Abstract
INTRODUCTION Treatment of Splenic (SMZL) and Nodal (NMZL) Marginal Zone Lymphoma is not consensual. Histologic transformation (HT) to aggressive lymphoma is a poorly understood event, with an unfavorable outcome. OBJECTIVES Describe the clinical characteristics, treatment, outcomes and incidence of HT. METHODS Characteristics of patients with SMZL and NMZL consecutively diagnosed in 8 Portuguese centers were retrospectively reviewed. Endpoints were overall survival (OS), time to first systemic treatment (TTFST), frequency of HT and time to transformation (TTT). RESULTS This study included 122 SMZL and 68 NMZL, most of them received systemic treatment: 55.4% and 76.5%, respectively. Splenectomy was performed in 58.7% of patients with SMZL. Different treatment protocols were used. OS or TTFST did not differ significantly according to treatments. Given the small sample size, no conclusion can be made concerning the role of Rituximab in the treatment of NMZL and SMZL based in these results. HT was documented in 18 patients, mainly in SMZL, with a cumulative incidence at 5 years of 4.2%. We confirmed that age is a prognostic factor. CONCLUSION Randomized prospective trials are needed to standardize treatment in MZL. Patients with HT did appear to have shorter OS in comparison with those who did not experience HT (OS 5 years of 68.4% vs. 80.4%), but the number of HT was too small to reach statistical significance.

Abstract
Background and Objectives: Hematological malignancies are usually systemic diseases of life-threatening impact, and frequently require prompt and energetic therapeutic intervention. Due to systemic involvement, the role of surgery is generally limited to diagnostic approaches, and it is very rarely employed as a therapeutic modality. Splenectomy represents an exception to this paradigm, being used both as a diagnostic and tumor debulking procedure, notably in splenic lymphomas. Materials and Methods: We investigated the role of splenectomy in a single center prospective study of splenectomy outcome in patients with splenic involvement in the course of lymphoproliferative disorders. In the present study, we included all patients treated in our department for lymphoid malignancies over a period of six years, who underwent splenectomy as a diagnostic or debulking procedure after referral and workup, or had been referred to our department after first being splenectomized and diagnosed with splenic lymphoma. Patient characteristics and treatment outcome were investigated. Results: We enrolled 54 patients, with 34 (63%) splenectomized patients: 12 splenectomies (22.2%) for diagnostic purposes and 22 (40.7%) for treatment. Special attention was given to the 28 (51.85%) patients diagnosed with splenic marginal zone lymphoma (SMZL), a subtype with a clear therapeutic indication for splenectomy. Average age of patients was 57.5 (±13.1) years with a higher prevalence of feminine gender (66.67%). Age above 60 years old (p = 0.0295), ECOG (Eastern Cooperative Oncology Group) > 2 (p = 0.0402) and B-signs (p nonsignificant (NS)) were most frequently found in SMZL patients. Anemia, and notably autoimmune anemia, was more frequent in SMZL versus other small-cell lymphomas and also in splenectomized patients, as was leukocytosis and lymphocytosis. Treatment of patients with lymphoproliferative disorders consisted of chemotherapy and/or splenectomy. Most SMZL patients received chemotherapy as first line treatment (61.5%) and had only partial response (57.7%). Second treatment line was splenectomy in 80% of patients who required treatment, followed by a 60% rate of complete response (CR). Splenectomy offered a higher complete response rate (twice as high than in non-splenectomized, regardless of histology type, p = NS), followed by a survival advantage (Overall Survival (OS)~64 versus 59 months, p = NS). Particularly, SMZL patients had a 4.8 times higher rate of CR than other non-Hodgkin lymphoma (NHL) patients (p = 0.04), a longer progression free survival (73 months vs. 31 months for other small-cell NHLs p = NS) and a 1.5fold lower death rate (p = NS). The procedure was rather safe, with a 38.5% frequency of adverse reactions, mostly minor and manageable. Conclusions: Our data suggest that splenectomy is an effective and safe therapeutic option in patients with lymphoid malignancies and splenic involvement, particularly splenic marginal zone lymphoma.

Abstract
Le lymphome à cellules de la zone marginale splénique (LZMS) est un lymphome B exceptionnel, bien définie dans la classification OMS 2016 des tumeurs hématopoïétiques, qui peut être source de pièges diagnostiques. Patiente âgée de 72 ans, hospitalisait pour l’exploration d’une énorme splénomégalie confirmée par une tomodensitométrie (TDM). Le bilan biologique était normal. Une splénectomie a été réalisée. L’étude microscopique de la pièce opératoire montrait une prolifération lymphomateuse diffuse à petites cellules, avec un marquage par le CD20. Le CD 5 et le CD 43 sont négatifs. Le diagnostic d’un LZMS a été retenu. Le LZMS est représente moins de 2% de l’ensemble lymphomes non hodgkiniens. Il touche le sujet âgé de plus de 50 ans, caractérisé habituellement par la présence d'une splénomégalie volumineuse sans adénopathies. L'hémogramme montre dans trois quarts des cas la présence inconstante de lymphocytes villeux. Le diagnostic est essentiellement anatomopathologique, il montre une atteinte constante nodulaire ou parfois diffuse de la pulpe blanche du parenchyme splénique. Les cellules tumorales sont de petite taille exprimant les marqueurs lymphoïdes B: CD19, CD20, CD22, CD79. Elles sont négatives pour le CD5, CD10, la cyclinde D1 et le CD43. Aucune anomalie cytogénétique spécifique du LZMS n'a été identifiée. C’est un lymphome indolent dont le traitement est jusqu’à ce jour non codifié, dépend des facteurs pronostiques. Le décès est lié au risque de transformation à un lymphome à grandes cellules.

Abstract
Splenic marginal zone lymphoma (SMZL) is a low-grade B-cell non-Hodgkin's lymphoma characterized by massive splenomegaly, moderate lymphocytosis with or without villous lymphocytes, rare involvement of peripheral lymph nodes and indolent clinical course. As a rare disease, with no randomized prospective trials, there is no standard of care for SMZL so far. Splenectomy has been done for many years as an attempt to control disease, but nowadays it has not been encouraged as first line because of new advances in therapy as rituximab, that are as effective with minimal toxicity. Facing these controversies, this review highlights advances in the literature regarding diagnosis, prognostic factors, treatment indications and therapeutic options.

Abstract
Splenic marginal zone lymphoma (SMZL) is a distinct lymphoma entity characterized by an indolent clinical course and prolonged survival. Treatment is not standardized, since there are no prospective randomized trials in large series of SMZL patients. Splenectomy and rituximab represent the most effective treatment strategies used so far. The addition of chemotherapy to rituximab has not further improved the outcome, although this issue requires further investigation. Rituximab monotherapy has been associated with high response rates (∼90%), with approximately half of these responses being complete, even at the molecular level. More importantly, many of these responses are long-lasting, with a reported 7-year progression-free survival (PFS) at the rate of 69%. Maintenance rituximab treatment has been associated with further improvement of the quality of response as well as longer response duration in studies derived from one group of investigators. Based on its high efficacy and the good safety profile, rituximab represent one of the best treatment options for SMZL patients. Moreover, rituximab retains its efficacy in the relapse setting in most cases. Splenectomy is a meaningful alternative to rituximab in patients with bulky splenomegaly and cytopenias, without extensive bone marrow infiltration, who are fit for surgery. However splenectomy cannot completely eradicate the disease and it is also associated with greater morbidity or even mortality compared to rituximab. The choice of one of these two treatment approaches (rituximab or splenectomy) should mainly be based on patient's characteristics and on the disease burden. Novel agents are currently testing in low grade lymphomas including a small number of SMZL patients with promising results.

Abstract
CHLAMYDIA AND OCULAR ADNEXAL LYMPHOMAS AN INDIAN EXPERIENCE: Ocular adnexal lymphomas (OALs) are a heterogeneous group of malignancies, majority being extranodal mucosa-associated lymphoid tissue (MALT) type. Different geographical regions have reported association of Chlamydia with OALs (MALT type). In India, role of Chlamydia in OALs remains unexplored. The aim of this study was to detect Chlamydia and to correlate with clinicopathological features of OALs in India. The clinicopathological features of 41 OAL cases were studied prospectively. Chlamydia DNA was detected by genus specific PCR amplifying major outer membrane protein (MOMP) gene followed by DNA sequencing. Chlamydia immunoexpression was evaluated by immunofluorescence and immunohistochemistry. The results were correlated with clinicopathological features including follow-up and survival. Chlamydia genome was detected in 3/41 (7.3%) OAL cases by PCR. Direct sequencing revealed C. trachomatis in 3 positive cases. Immunofluorescence and immunohistochemistry showed Chlamydia antigen in 5/41 and 1/41 cases respectively. Immunofluorescence demonstrated higher sensitivity than immunohistochemistry. A significant association was observed between Chlamydia positivity and orbital location (P=0.05). Follow-up revealed relapse in 2 Chlamydia positive cases (P=0.056). Our results demonstrate for the first time presence of C. trachomatis genome in 7.3% OAL cases in India. As no other reports are documented, more detailed studies from different regions within India are needed to explore status of Chlamydia in OALs.

Abstract
Background Splenic marginal zone lymphoma (SMZL) is a chronic B-cell lymphoproliferative disorder, comprising less than 2% of non-Hodgkin’s lymphomas, and affecting mainly middle-aged and elderly patients with a median survival of >10 years. The typical clinical features of SMZL include splenomegaly. Treatment should be patient-tailored and can range from a ‘watchful waiting’ approach for asymptomatic patients without cytopenias to surgery, localized radiation therapy or immuno/chemotherapies. Recently, the combination of rituximab and Bendamustine (R-Benda) has been defined as highly active in patients with follicular lymphomas, but little is known about the efficacy of R-Benda in SMZL. Aim of the study The purpose of this retrospective study was to report our experience on the efficacy of R-Benda as first line treatment in 23 consecutive elderly SMZL patients. Results All patients had a complete resolution of splenomegaly along with restoration of their blood counts. Nineteen patients (83%) achieved a complete response (CR) to therapy; three patients (13%) achieved a partial response (PR).Ten patients (43%) obtained molecular remission. Toxicities were mild and mainly haematological and result in dose reductions for fourteen patients. Conclusions Our data suggest a high activity and good tolerance of R-Benda, despite dose reduction due to potential toxicity.

Abstract
We describe a case presenting complaint of complete lower body paraparesis, which was discovered to have splenic marginal zone lymphoma (SMZL). While paraneoplastic syndromes are more common in tumors, such as small cell lung cancer, very few reports exist on this condition with SMZL. We describe such a rare entity with a clinical course spanning twenty-four months after diagnosis.

Abstract
AbstractSplenic marginal zone lymphoma (SMZL) is a rare B-cell malignancy involving the spleen, bone marrow, and frequently the blood. SMZL lymphomagenesis involves antigen and/or superantigen stimulation and molecular deregulation of genes (NOTCH2 and KLF2) involved in the physiological differentiation of spleen marginal zone B cells. Diagnosis requires either spleen histology or, alternatively, the documentation of a typical cell morphology and immunophenotype on blood cells coupled with the detection of intrasinusoidal infiltration by CD20+ cells in the bone marrow. Among B-cell tumors, deletion of 7q and NOTCH2 mutations are almost specific lesions of SMZL, thus representing promising diagnostic biomarkers of this lymphoma. Although the majority of SMZLs show an indolent course with a median survival of approximately 10 years, nearly 30% of patients experience a poor outcome. No randomized trials are reported for SMZL, and few prospective trials are available. A watch-and-wait approach is advisable for asymptomatic patients. Treatment options for symptomatic patients ranges from splenectomy to rituximab alone or combined with chemotherapy. In some geographic areas, a subset of patients with SMZL associates with hepatitis C virus infection, prompting virus eradication as an effective lymphoma treatment. It would be worthwhile to explore deregulated cellular programs of SMZL as therapeutic targets in the future; improved clinical and biological prognostication will be essential for identifying patients who may benefit from novel approaches.

Abstract
We describe a method for leukocyte sorting by a microarray of anti-cluster-of-differentiation (anti-CD) antibodies and for preparation of the bound cells for morphological or cytochemical examination. The procedure results in a “sorted” smear with cells positive for certain surface antigens localised in predefined areas. The morphology and cytochemistry of the microarray-captured normal and neoplastic peripheral blood mononuclear cells are identical to the same characteristics in a smear. The microarray permits to determine the proportions of cells positive for the CD antigens on the microarray panel with high correlation with flow cytometry. Using the anti-CD microarray we show that normal granular lymphocytes and lymphocytes with radial segmentation of the nuclei are positive for CD3, CD8, CD16 or CD56 but not for CD4 or CD19. We also show that the described technique permits to obtain a pure leukemic cell population or to separate two leukemic cell populations on different antibody spots and to study their morphology or cytochemistry directly on the microarray. In cases of leukemias/lymphomas when circulating neoplastic cells are morphologically distinct, preliminary diagnosis can be suggested from full analysis of cell morphology, cytochemistry and their binding pattern on the microarray.

Abstract
Splenic marginal zone lymphoma (SMZL) accounts for less than 2% of all non-Hodgkin lymphomas. We identified 107 cases diagnosed with SMZL between 1985 and 2012 from the British Columbia Cancer Agency Centre for Lymphoid Cancer and Lymphoma Pathology Databases. Patient characteristics were: median age 67 years (range 30-88), male 40%, stage IV 98%, splenomegaly 93%, bone marrow involvement 96%, peripheral blood involvement 87%. As initial treatment, 52 underwent splenectomy (10 with chemotherapy), 38 chemotherapy alone (21 chemoimmunotherapy containing rituximab, 1 rituximab alone), two antivirals for hepatitis C, and 15 were only observed. The 10-year overall survival for first-line splenectomy versus chemotherapy was 61% and 42%, respectively [Hazard Ratio (HR) 0·48, 95% confidence interval (CI) 0·26-0·88, P = 0·017]. The 10-year failure-free survival (FFS) after first-line splenectomy vs chemotherapy was 39% and 14%, respectively (HR 0·48, 95% CI 0·28-0·80, P = 0·004). Among the 38 patients who received first-line chemotherapy, FFS was similar between those receiving rituximab (n = 22) and those who did not (n = 16) (HR 0·64, 95% CI 0·31-1·34, P = 0·238). Fifteen patients transformed to aggressive lymphoma with median time to transformation of 3·5 years (range 6 months to 12 years) and the 10-year transformation rate was 18%. In conclusion, splenectomy remains a reasonable treatment for patients with SMZL.

Abstract
Splenic marginal zone lymphoma (SMZL) comprises about 1% of B-cell lymphomas and typically occurs after the age of 50 years. Pediatric SMZL is very rare, and no FDG PET/CT imaging of the disease has been reported. In the current study, a 4-year-old boy with biopsy-proven SMZL had FDG PET/CT for staging, which showed increased metabolic activity in the spleen and left cervical lymph nodes. A second FDG PET/CT for evaluation of treatment response showed complete resolution of abnormal FDG uptake in the nodes and spleen with decrease in size of the nodes.

Abstract
Splenic marginal zone lymphoma (SMZL) is a lymphoma recognized as a distinct entity in the WHO classification of the lymphoid tumors. SMZL probably results from the expansion of a marginal zone B-cell driven by persistent antigen stimulation. SMZL is clinically and biologically heterogeneous. The SMZL Working Group has published guidelines for the diagnosis, workup and treatment of SMZL. There are no standard criteria to initiate treatment. A policy of watch and wait in asymptomatic patients is recommended. In symptomatic patients, data from retrospective studies suggest that rituximab with or without chemotherapy is the best strategy for SMZL. It is uncertain which is the optimal type of chemotherapy and whether patients may benefit from splenectomy prior chemoimmunotherapy. In the future, we may see progress with agents targeting known molecular lesions in SMZL.

Abstract
PURPOSE OF REVIEW Indolent B-cell lymphomas that are supposed to derive from marginal zone encompass three distinct entities: extranodal marginal zone lymphoma (MZL) or mucosa-associated lymphatic tissue (MALT), nodal MZL (NMZL) and splenic MZL (SMZL). Although MALT lymphoma is well characterized and extensively studied at the clinical and molecular levels, SMZL and NMZL remain incompletely characterized. However, during the last years, the clinical and molecular heterogeneity of SMZL has been clarified. The recent 2008 WHO classification has maintained the distinction between the three diseases according to the organ where it arises and introduced a new provisional category of unclassified splenic lymphoma for overlapping entities, splenic diffuse red pulp lymphoma (SDRPL) and hairy cell leukemia-variant (HCL-V). RECENT FINDINGS Recent findings in SMZL contributed to a better characterization, including the few cases associated with hepatitis C, the recurrence of 7q deletion and the possibility of CD5 expression. Furthermore, the peculiar pattern of immunoglobulin heavy chain genes mutations and the biased usage of immunoglobulin heavy chain variable region genes (IGHV)1-2 segment are suggestive of a T-independent antigen driven proliferation, at least at initial steps. This review will focus on recent findings and differential diagnosis with SDRPL and HCL-V. SUMMARY The conjunction of morphologic, cytogenetic and clinical data has increased diagnosis reproducibility.

Abstract
BACKGROUND Treatment of splenic marginal zone lymphoma (SMZL) patients is not standardized. Recent data suggest that rituximab is highly effective and could be considered as initial therapy. AIM To assess the efficacy of rituximab monotherapy in a large series of patients with SMZL and compare these results with splenectomy results. METHODS The studied population included 85 patients. Fifty-eight received rituximab at a dose of 375 mg/m2 per week for 6 weeks as induction followed by maintenance at the same dose every 2 months for 1-2 years, whereas 27 patients were treated using splenectomy only. RESULTS The overall response rate to rituximab 2 months after the end of induction was 95% (complete response [CR], 45%; unconfirmed CR, 26%; partial response, 24%). The median times to hematologic and clinical response were 2 weeks and 3 weeks, respectively. Forty-three of 55 patients already completed the maintenance phase: 28 sustained their initial response, 14 improved their response, and one progressed. Eighty-five percent of splenectomized patients responded, and two were treated with rituximab as consolidation after splenectomy and achieved a CR. The 5-year overall and progression-free survival (PFS) rates for rituximab-treated and splenectomized patients were 92% and 77% (p = .09) and 73% and 58% (p = .06), respectively. Furthermore, maintenance therapy with rituximab resulted in a longer duration of response (at 5 years, PFS was 84% for patients receiving maintenance and 36% for patients without maintenance, p <.0001). CONCLUSIONS Rituximab is a very effective and well-tolerated therapy and may be substituted for splenectomy as the first-line treatment of choice for patients with SMZL.

Abstract
The incidental finding of an isolated splenomegaly during clinical assessment of patients evaluated for unrelated causes has become increasingly frequent because of the widespread use of imaging. Therefore, the challenging approach to the differential diagnosis of spleen disorders has emerged as a rather common issue of clinical practice. A true diagnostic dilemma hides in distinguishing pathologic conditions primarily involving the spleen from those in which splenomegaly presents as an epiphenomenon of hepatic or systemic diseases. Among the causes of isolated splenomegaly, lymphoid malignancies account for a relevant, yet probably underestimated, number of cases. Splenic lymphomas constitute a wide and heterogeneous array of diseases, whose clinical behavior spans from indolent to highly aggressive. Such a clinical heterogeneity is paralleled by the high degree of biologic variation in the lymphoid populations from which they originate. Nevertheless, the presenting clinical, laboratory, and pathologic features of these diseases often display significant overlaps. In this manuscript, we present our approach to the diagnosis and treatment of these rare lymphomas, whose complexity has been so far determined by the lack of prospectively validated prognostic systems, treatment strategies, and response criteria.

Abstract
BACKGROUND A retrospective review and analysis of 275 patients with marginal zone lymphoma (MZL) was performed to determine prognostic factors. An effort was also made to establish a specific prognostic score for patients with extranodal MZL. METHODS Patients were divided into 3 groups according to the type of MZL: extranodal, nodal, and splenic. Factors analyzed included age; gender; presence of B symptoms; Zubrod performance score; clinical stage; serum β(2)-microglobulin, lactate dehydrogenase, albumin, and hemoglobin levels; and presence of autoimmune disorder. RESULTS The 5-year overall survival rates of patients with extranodal, nodal, and splenic MZL were 87%, 89%, and 93%, respectively (P = .95). On multivariate analysis, splenic MZL patients had the best prognosis (hazard ratio, 0.18; P = .018). An elevated serum β(2)-microglobulin level (P = .010), B symptoms (P = .021), and male gender (P = .036) were found to be correlated with decreased recurrence-free survival (RFS) on multivariate analysis. Using these 3 variables, a 3-tier prognostic scoring system was created for patients with extranodal MZL: low-risk with no adverse factors, intermediate-risk with 1 adverse factor, and high-risk with ≥ 2 adverse factors. The 5-year RFS rates for the low-risk, intermediate-risk, and high-risk groups were 80%, 71%, and 44%, respectively (P = .01). CONCLUSIONS Patients with extranodal and nodal MZL have a similar prognosis, whereas patients with splenic MZL have a better prognosis despite the increased prevalence of negative prognostic indicators. With the use of 3 readily available factors, a prognostic scoring system was identified for patients with extranodal MZL.

METHODS: A total of 30 patients with typical histological and immunohistochemical SMZL patterns were examined. Splenectomy plus chemotherapy was applied in 20 patients, while splenectomy as a single treatment-option was performed in 10 patients. Prognostic factor and overall survival rate were analyzed.
RESULTS: Complete remission (CR) was achieved in 20 (66.7%), partial remission (PR) in seven (23.3%), and lethal outcome due to disease progression occurred in three (10.0%) patients. Median survival of patients with a splenectomy was 93.0 mo and for patients with splenectomy plus chemotherapy it was 107.5 mo (Log rank = 0.056, P > 0.05). Time from onset of first symptoms to the beginning of the treatment (mean 9.4 mo) was influenced by spleen dimensions, as measured by computerized tomography and ultra-sound (t = 2.558, P = 0.018). Strong positivity (+++) of CD20 antigen expression in splenic tissue had a positive influence on OS (Log rank = 5.244, P < 0.05). The analysis of factors interfering with survival (by the Kaplan-Meier method) revealed that gender, general symptoms, clinical stage, and spleen infiltration type (nodular vs diffuse) had no significant (P > 0.05) effects on the OS. The expression of other antigens (immunohistochemistry) also had no effect on survival-rate, as measured by a χ2 test (P > 0.05).
CONCLUSION: Initial splenectomy combined with chemotherapy has been shown to be beneficial due to its advanced remission rate/duration; however, a larger controlled clinical study is required to confirm our findings.

Abstract
INTRODUCTION Autoimmune manifestations are common in splenic marginal zone lymphoma (SMZL) and are sometimes the presenting feature of the disease. Autoimmune cytopenia (anemia, thrombocytopenia) are the most frequently reported autoimmune conditions. However, other immunological manifestations may be associated with SMZL. METHODS We report a retrospective case series of six patients with SMZL associated with autoimmunity. RESULTS Auto-immune manifestations were the presenting feature of lymphoma in four cases. Auto-immune manifestations included auto-immune cytopenia in three cases (two hemolytic anemia and one pancytopenia), thyroiditis in two cases, systemic lupus and Still's disease in one case each. Antinuclear antibodies were detected with a titre of 1/250 in three cases, and with a titre of 1/32,000 in the patient with systemic lupus. Testing for DNA antibodies was negative in all cases. Two patients had a circulating lupus anticoagulant, with portal venous thrombosis following splenectomy in one case. One patient had hypogammaglobulinemia. A monoclonal gammopathy was detected in three patients. All patients had spleen enlargement. Immunophenotyping of blood peripheral lymphocyte was typical in five out of the six cases. Bone marrow was infiltrated in five out of the six cases. Diagnosis was obtained by the combination of immunophenotyping and bone marrow histopathology in five cases, and by splenic histopathology in the remaining case. Hepatitis C virus serology was negative in all patient. CONCLUSION Autoimmune disease as systemic lupus or Still's disease may be associated with SMZL before its tumoral manifestations are evident. In this mode of presentation, spleen enlargement, hypogammaglobulinemia, monoclonal gammopathy, and multiple autoimmune diseases, should alert the physician.

Abstract
The case of a woman with insulin-dependent diabetes mellitus, autoimmune thyroiditis, atrophic gastritis, pernicious anemia, and immunologic thrombocytopenic purpura consisting of autoimmune polyglandular syndrome type 3 associated with a history of gonadal failure is reported. Hepatitis C viral infection added xerophthalmia, lymphocytic sialadenitis, and exacerbation of idiopathic thrombocytopenic purpura. This unique disease constellation was complicated with splenic marginal zone lymphoma and gastric carcinoids. A lung infection, initially treated on an outpatient basis, proved fatal to the patient.

Abstract
Two subtypes of splenic marginal zone lymphoma (SMZL) are identified in the World Health Organization (WHO) classification: SMZL without villous lymphocytes and SMZL with villous lymphocytes in the peripheral blood (SLVL). SLVL is a rare leukemic and indolent B-cell chronic lymphoproliferative disorder (B-CLPD) that we have to differentiate from hairy cell leukemia (HCL), B prolymphocytic leukemia (B-PLL) and follicular lymphoma (FL). Morphological examination associated with immunophenotyping is, in most cases, likely to distinguish these CD5 negative entities. However, the diagnosis can be difficult to make on morphological criteria, especially in patients without absolute lymphocytosis. Based on histologic, cytogenetic and molecular studies, SLVL emerges as a distinct entity. SLVL has a relatively clinical benign course but a few patients could require treatment, because of a symptomatic splenomegaly and/or a severe cytopenia. In symptomatic patients HCV negative, the frontline treatment remains questionable. Splenectomy, regarded as the most effective treatment, could be required for diagnostic purposes: however, relapse occur in 30% of cases. Fludarabine (FDR), a purine analogue and deoxycoformycin (DCF) can induce a maintained response in a substantial proportion of patients with SLVL and could be used as a first line treatment. In HCV + SLVL patients, antiviral treatment using alpha interferon and ribavirin can induce regression of SLVL.

Abstract
Since the initial description of splenic marginal zone lymphoma (SMZL) in 1992, an increasing number of publications have dealt with multiple aspects of SMZL diagnosis, molecular pathogenesis and treatment. This process has identified multiple inconsistencies in the diagnostic criteria and lack of clear guidelines for the staging and treatment. The authors of this review have held several meetings and exchanged series of cases with the objective of agreeing on the main diagnostic, staging and therapeutic guidelines for patients with this condition. Specific working groups were created for diagnostic criteria, immunophenotype, staging and treatment. As results of this work, guidelines are proposed for diagnosis, differential diagnosis, staging, prognostic factors, treatment and response criteria. The guidelines proposed here are intended to contribute to the standardization of the diagnosis and treatment of these patients, and should facilitate the future development of clinical trials that could define more precisely predictive markers for histological progression or lack of response, and evaluate new drugs or treatments.

Abstract
Splenic marginal zone lymphoma with or without villous lymphocytes (SLVL/SMZL) is a low grade B-cell lymphoma that affects patients in the sixth decade and has a median survival greater than 10 years. A substantial proportion of patients die from causes unrelated to the disease. Close to a third of the patients do not require intervention and a policy of watch and see is reasonable and recommended. There are several therapeutic options that have proved effective in these patients. Due to the natural history of the lymphoma, the main goal of all these treatments is to achieve control of the disease rather than its eradication. Retrospective designs of all documented studies, the lack of uniform response criteria and the heterogeneity in the patient's features makes interpretation of the data difficult. Splenectomy remains one of the first line options in patients fit for surgery. Amongst chemotherapy, purine analogues, in particular fludarabine in combination or not with Rituximab and Rituximab alone have a greater efficacy than alkylating agents in terms of achieving better quality of response and longer progression free survival; therefore these agents are recommended particularly in patients who are not candidates for surgery or relapse after splenectomy. In the small proportion of patients with concomitant hepatitis C virus (HCV) infection, Interferon-alpha, ribavirin or a combination of both has demonstrated a significant activity with responses correlating with clearance of HCV RNA in the blood; therefore, these agents should be considered in the therapeutic scenario as a first line in these small cohort of patients. Patients that transform to high-grade lymphoma and the minority that have TP53 abnormalities should be treated with other schedules. Prospective randomized trials would be desirable to ascertain the independent prognostic factors and the biological features that predict disease progression and drug resistance to device the optimal management and treatment for SLVL/SMZL.

Abstract
Herein, we report on a patient with splenic marginal zone lymphoma who initially presented without splenomegaly and bone marrow (BM) or peripheral blood involvement. At first, the patient showed moderate leukothrombocytopenia; she was completely asymptomatic, and BM examination excluded a hematologic disease. After 7 months, spleen enlargement was detected without determining any symptoms or worsening of the bilinear cytopenia. Bone marrow histologic, immunohistochemic, cytologic, and immunophenotypic examinations were normal. Splenectomy was performed, and a diagnosis of splenic marginal zone B-cell lymphoma was established. A monoclonal IgVH gene rearrangement was identified in the spleen tissue (VH3 gene family) and subsequently detected in the BM mononuclear cells. Because of the large surgical debulking and the absence of histologic, cytologic, and immunophenotypic BM involvement, no further treatment was proposed. After the splenectomy, the blood cell count normalized, and neither BM nor peripheral blood involvement appeared after 12 months of follow-up.

Abstract
OBJECTIVE To characterize the clinical and immunologic patterns of expression, response to therapy, and outcome of patients with Sjögren's syndrome (SS) and associated hepatitis C virus (HCV) infection who developed B cell lymphoma. METHODS Various international reference centers constituted a multicenter study group with the purpose of creating a registry of patients with SS-HCV who developed B cell lymphoma. A protocol form was used to record the main characteristics of SS, chronic HCV infection, and B cell lymphoma. RESULTS Twenty-five patients with SS-HCV with B cell lymphoma were included in the registry. There were 22 (88%) women and 3 (12%) men (mean age 55, 58, and 61 years at SS, HCV infection, and lymphoma diagnosis, respectively). The main extraglandular SS manifestations were cutaneous vasculitis in 15 (60%) patients and peripheral neuropathy in 12 (48%); the main immunologic features were positive rheumatoid factor (RF) in 24 (96%) and type II cryoglobulins in 20 (80%). The main histologic subtypes were mucosa-associated lymphoid tissue (MALT) lymphoma in 11 (44%) patients, diffuse large B cell lymphoma in 6 (24%), and follicular center cell lymphoma in 6 (24%). Fifteen (60%) patients had an extranodal primary location, most frequently in the parotid gland (5 patients), liver (4 patients), and stomach (4 patients). Twelve (52%) of 23 patients died after a median followup from the time of lymphoma diagnosis of 4 years, with lymphoma progression being the most frequent cause of death. Survival differed significantly between the main types of B cell lymphoma. CONCLUSION Patients with SS-HCV and B cell lymphoma are clinically characterized by a high frequency of parotid enlargement and vasculitis, an immunologic pattern overwhelmingly dominated by the presence of RF and mixed type II cryoglobulins, a predominance of MALT lymphomas, and an elevated frequency of primary extranodal involvement in organs in which HCV replicates (exocrine glands, liver, and stomach).

Abstract
BACKGROUND The optimal management of patients with splenic marginal zone lymphoma/marginal zone lymphoma (SMZL) is controversial. The objective of this retrospective study was to compare the outcomes of patients with SMZL who received treatment with rituximab, rituximab plus chemotherapy, or chemotherapy alone. METHODS The Leukemia Service database was searched for patients with splenic lymphoma who were registered between May 1995 and October 2004. The indications for treatment were the same as those used for patients with chronic lymphocytic leukemia. RESULTS SMZL was confirmed in 70 patients. The median age was 64 years. The median number of CD20 molecules per cell was 69 x 10(3). Forty-three patients required systemic therapy; rituximab in 26 patients, chemotherapy plus rituximab in 6 patients, and chemotherapy alone in 11 patients. Ten additional patients underwent splenectomy, and 17 patients were in the observation group. The overall response rates were 88% with rituximab, 83% with rituximab plus chemotherapy, and 55% with chemotherapy alone; the 3-year survival rates were 95%, 100%, and 55%, respectively. The 3-year failure-free survival (FFS) rates were 86%, 100%, and 45% in the rituximab, rituximab plus chemotherapy, and chemotherapy alone groups, respectively. Rituximab treatments resulted in longer survival and FFS compared with chemotherapy. Rituximab alone resulted in disappearance of splenomegaly in 92% of patients and normalization of absolute lymphocyte counts. In univariate analysis, younger age and rituximab-based therapy were predictive of longer FFS. CONCLUSIONS Rituximab with or without chemotherapy was found to have major activity in patients with SMZL. These results may be associated with high levels of cellular CD20 antigen sites. Rituximab should be the treatment of choice, at least in older patients with SMZL who have comorbid diseases.

Abstract
OBJECTIVES Solid second primary cancers (SPC) have become an issue of extensive research. The purpose of the present study was to estimate the standardised incidence ratio (SIR) and the absolute excess risk (AER) of SPC in patients with splenic marginal zone lymphoma (SMZL). METHODS We investigated the incidence of additional cancers in 129 patients consecutively diagnosed with SMZL in three Italian haematological centres, asking the cooperating doctors for additional information on initial and subsequent therapies and on the onset and type of second cancers. RESULTS Twelve SPC were recorded (9.3%); the 3- and 5-yr cumulative incidence rates were 5.5% and 18.3% respectively, with an SIR of 2.03 [95% confidence interval (CI): 1.05-3.56; P < 0.05; AER = 145.81]. Of 12 SPC observed, four were urinary tract neoplasms (SIR, 3.70; 95% CI: 1.01-9.48; P < 0.05; AER = 70.06), four were lung cancers (SIR, 9.16; 95% CI: 1.41-13.25; P < 0.05; AER = 85.50) and the other four were hepatic carcinoma, endometrial cancer, breast cancer and colorectal cancer. CONCLUSIONS Our findings evidence a high frequency of additional cancers in patients with SMZL and suggest that the incidence rate of SPC is significantly different from that expected in the general population. The frequency of cases with urinary tract and lung malignancies in our series is higher than expected. Although confirmatory data are needed, it is our opinion that SMZL patients are at risk of second cancer and should be carefully investigated on diagnosis and monitored during the follow-up.

Abstract
BACKGROUND Splenic marginal zone lymphoma (SMZL) is an infrequent B-cell neoplasm that pursues an indolent course. Signs and symptoms, mostly related to hypersplenism, are successfully managed by splenectomy. However, the therapy of patients who are not fit for a surgical procedure or who relapse after splenectomy, is still an unsettled issue. PATIENTS AND METHODS We report a phase-II study on 16 patients with SMZL, three therapy naïve and 13 pretreated, all showing systemic symptoms or progressive worsening of peripheral cytopenia, who were treated with pentostatin at a dose of 4 mg/m2 every other week for 6-10 wk. In relapsed patients, the median interval between diagnosis and treatment was 26 month (range: 8-49). RESULTS Overall, 68% of the patients showed a clinical response. Two out three patients, who received pentostatin as first line therapy, attained a complete response (CR). One CR and seven minor or good haematological responses were recorded in relapsed patients. Treatment toxicity, mostly haematological, proved manageable. With a median follow-up of 35 month the median overall survival (OS) is 40 month and the median progression free survival (PFS) is 18 month. CONCLUSION Our data show that pentostatin administered every other week has a good degree of activity in the treatment of SMZL and suggest that this schedule could be considered a possible therapeutic option for patients who are not fit for splenectomy or have relapsed.
