Here, we present the first cytological report of a primary splenic inflammatory pseudotumor-like follicular dendritic cell sarcoma. The 57 year-old male was incidentally found with a 2.2 cm well-demarcated splenic nodule. A sonography guided fine needle aspiration of the lesion was performed. The cytologic smears revealed loosely cohesive fragments of oval to spindle cells in a background of prominent lymphoplasmacytic infiltration. The cells showed sparse chromatin, distinct nucleoli, syncytial cell borders, and occasional cytoplasmic processes...

Anaplastic lymphoma kinase-positive large B-cell lymphoma (ALK+ LBCL) is a rare distinct type of non-Hodgkin's lymphoma that arises in association with alterations of the ALK gene. This distinct disease entity is typically associated with an aggressive clinical course and appears in light microscopic preparations as a monomorphic population of large, immunoblast-like cells. In this report, we describe a case of ALK+ LBCL diagnosed by transgastric endoscopic ultrasound-guided fine needle aspiration (EUS FNA) of splenic hilar lymph nodes...

We recently reported a truncating deletion in the NFKBIE gene, which encodes IκBϵ, a negative feedback regulator of NF-κB, in clinically aggressive chronic lymphocytic leukemia (CLL). Preliminary data indicate enrichment of NFKBIE aberrations in other lymphoid malignancies, hence we screened a large patient cohort (n=1460) diagnosed with different lymphoid neoplasms. While NFKBIE deletions were infrequent in follicular lymphoma, splenic marginal-zone lymphoma, and T-cell acute lymphoblastic leukemia (<2%), slightly higher frequencies were seen in diffuse large B-cell lymphoma, mantle cell lymphoma, and primary CNS lymphoma (3-4%)...

Marginal zone lymphoma (MZL) is a low-grade B-cell lymphoma derived from marginal-zone B cells. Because of a lack of specific immunohistochemical markers, MZL is mainly diagnosed based on the cytological appearance and growth pattern of the tumor. Marginal-zone B cells were recently shown to selectively express immunoglobulin superfamily receptor translocation-associated 1 (IRTA1), but the antibody used in that study is not commercially available. We therefore investigated the IRTA1 expression in non-neoplastic lymphoid tissues and 261 malignant lymphomas, examining the ability of a commercially available antibody to accurately diagnose MZL...

It is unclear if persistent splenomegaly in the presence of a negative positron emission tomography (PET) scan before allogeneic hematopoietic cell transplantation (HCT) influences post-transplantation outcomes in patients with lymphoma. We retrospectively reviewed records of 152 patients who underwent allogeneic HCT for various lymphomas. Centralized review of pretransplantation computed tomography (CT) and PET images was performed. Spleen volume (SV) was measured using the freehand volume segmentation tool in AW Workstation software (General Electric, Waukesha, WI)...

BACKGROUND: Portal and/or splenic vein thrombosis (PSVT) is common after splenectomy. It can be a life-threatening complication, with a risk of bowel ischemia and portal hypertension. An early diagnosis allows an effective medical treatment and prevents life-threatening complications. There is no consensus regarding the benefit of systematic screening of patients after splenectomy for PSVT. We started in January 2012 a routine screening of PSVT after elective splenectomy. The aim of this study was to assess this policy...

INTRODUCTION: Acute neuropathic pain and weakness with a sensory level in a patient with a history of lymphoma has a broad differential diagnosis. Evaluation of such a presentation often includes MRI, neurophysiologic studies, and cerebrospinal fluid evaluation. We report a patient with splenic marginal zone lymphoma who developed acute weakness, sensory loss, and neuropathic pain due to neurolymphomatosis. METHODS: Clinical evaluation, MRI of the lumbar spine, cerebrospinal fluid evaluation, electrodiagnostic (EDX) studies, and biopsy of the dorsal nerve root were undertaken...

B-cell lymphoma (BCL), unclassifiable, with features intermediate between diffuse large BCL (DLBCL) and classical Hodgkin's lymphoma (CHL), is a novel entity to the World Health Organization classification system. These tumors are rare aggressive lymphomas that have a poor prognosis. The present study reports the case of a patient with one such lymphoma that occurred in the spleen, which expressed cluster of differentiation (CD)20, CD79α, melanoma associated antigen (mutated) 1, BCL6, CD15 and CD30. Polymerase chain reaction analysis demonstrated a clonal rearrangement of the genes coding for immunoglobulin heavy chains...

A 48-year-old man was transferred to our emergency room because of sudden-onset epigastric pain and nausea. Abdominal contrast-enhanced computed tomography (CT) showed splenomegaly with splenic infarction and intra-abdominal bleeding, suggestive of splenic rupture. An emergent open splenectomy was performed. His spleen was markedly swollen and showed continuous bleeding due to a laceration. On histopathological examination, his spleen was filled with abnormal tumor cells. He was diagnosed as having mantle cell lymphoma based on the findings of immunohistochemical and cytogenetic analyses of the spleen...

CONTEXT: Splenic diffuse red-pulp small B-cell lymphoma is a rare disease, representing less than 1% of all non-Hodgkin lymphomas (NHL). This entity is characterized by involvement of bone marrow sinusoids and peripheral blood. The majority of cases are at an advanced stage when diagnosed. Its pathogenesis is still poorly understood. CASE REPORTS: We report on two patients with chronic non-replicating hepatitis B virus (HBV) who developed splenic diffuse red-pulp small B-cell lymphoma...

As reported previously, large numbers of neutrophils appear in the circulation during tumor development. However, the relationship between these cells and myeloid-derived suppressor cells (MDSCs), as well as their susceptibility to myelosuppressive drugs have not been yet investigated. Here, we employed a lymphoma model to characterize tumor-associated circulating neutrophils, including their sensitivity to 5-fluorouracil (5-FU), busulfan (Bu) or treosulfan (Treo). Tumor-bearing mice exhibited pronounced elevations in the numbers of splenic MDSCs and circulating neutrophils, MDSCs, and granulocytic-MDSCs (G-MDSCs)...

Acquired angioedema (AAE) due to C1-inhibitor (C1INH) deficiency is rare. Treatment options for acute attacks are variable and used off-label. Successful treatment of the associated lymphoma with rituximab seems to prevent acute attacks in subjects with AAE. The aim of this study was to describe AAE manifestations, its associated diseases, and patients' responses to treatments in a representative cohort.A retrospective nationwide study was conducted in France. The inclusion criteria were recurrent angioedema attacks and an acquired decrease in functional C1INH <50% of the reference value...

The aim of this study was to investigate follicular helper T (Tfh) cell response and its difference between renal graft and spleen in a rat renal transplantation model undergoing chronic allograft nephropathy (CAN). Orthotopical kidney transplantations were performed on Fischer (F344) rats and transplanted to Lewis rats, using syngeneic Lewis-Lewis grafts as controls. Tissue samples were collected at 8 weeks post-transplantation. The status of Tfh cell response was assessed by measuring the levels of transcription factor B-cell lymphoma 6 (Bcl-6), interleukin 21 (IL-21), chemokine receptor type 5 (CXCR5), and B cell activating factor belonging to the TNF family (BAFF)...

Splenic marginal zone lymphoma is a rare mature B-cell malignancy involving the spleen, bone marrow and blood. Over the past years, the rapid expansion of sequencing technologies allowing the genome-wide assessment of genomic, epigenetic and transcriptional changes has revolutionized our understanding of the biological basis of splenic marginal zone lymphoma by providing a comprehensive and unbiased view of the genes/pathways that are deregulated in this disease. NF-κB is a family of transcription factors that plays critical roles in development, survival, and activation of B lymphocytes...

Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a rare subtype of Hodgkin lymphoma with distinct clinicopathologic features. It is typified by the presence of lymphocyte predominant (LP) cells, which are CD20(+) but CD15(-) and CD30(-) and are found scattered amongst small B lymphocytes arranged in a nodular pattern. Despite frequent and often late or multiple relapses, the prognosis of NLPHL is very favorable. There is an inherent risk of secondary aggressive non-Hodgkin lymphoma (NHL) and studies support that risk is highest in those with splenic involvement at presentation...
