Splenic marginal zone lymphoma (SMZL) is a rare indolent B-cell malignancy involving the spleen and bone marrow. Various cytogenetic abnormalities with prognostic value have been identified in SMZL. Complexity of karyotype, 14q aberrations, and TP53 deletions have been found to be poor prognostic indicators. We report an unusual case of SMZL with a complex karyotype including 17p deletion, primarily refractory to 2 chemoimmunotherapy regimens, that responded well to treatment with phosphatidylinositol-3-kinase delta (PI3Kδ) inhibitors idelalisib and rituximab...

PURPOSE: The detection rate and the metabolic behavior of 18F-FDG-PET/CT in splenic marginal zone lymphoma (SMZL) are not yet clear. Our aim was to investigate the metabolic behavior of SMZL and whether the tumor stage (acc. Ann Arbor) epidemiological (age, gender), histological (Ki-67 index, plasmacytic differentiation), and morphological (splenic diameter maximum) features might be related to 18F-FDG PET/CT results. METHODS: Fifty-one patients (34 male, 17 female; average age 70 years) with histologically confirmed SMZL who underwent a 18F-FDG PET/CT for initial staging were included: PET/CT images were analyzed visually and semi-quantitatively (SUVmax, lesion-to-liver SUVmax ratio, and lesion-to-blood pool SUVmax ratio)...

BACKGROUND: Burkitt lymphoma is a highly aggressive B cell non-Hodgkin lymphoma. Cross-sectional imaging techniques that are used to detect liver and spleen involvement by lymphoma have high rates of false negative and false positive findings, and as such may reduce the accuracy of staging. PURPOSE: This retrospective study evaluated the use of FDG PET-CT in determining splenic involvement at staging, in a relatively large cohort of adult patients with the sporadic form of Burkitt lymphoma (SBL)...

SMZL is a relatively rare low grade B-cell lymphoma, characterized usually by an indolent clinical behavior. Since there is no prospective randomized trials to establish the best treatment approach, decision on therapeutic management should be based on the available retrospective series. Based on these data, rituximab and splenectomy appear to be the most effective. Splenectomy represented the standard treatment modality until early 2000s. More than 90% of the patients present quick amelioration of splenomegaly related symptoms along with improvement of cytopenias related to hypersplenism...

This is the first in-man clinical study of 18F-fludarabine which is a radiopharmaceutical for PET imaging in lymphoma where many issues remain controversial with the standard radiotracer 18F-FDG. Methods:18F-Fludarabine-PET(/CT) was performed in 10 patients: five with diffuse large B-cell lymphoma (DLBCL) and five with chronic lymphocytic leukemia (CLL). The biodistribution, and radiation dosimetry of 18F-fludarabine have also been evaluated. Six successive partial body PET scans were acquired for 250 min after intravenous 4 MBq/kg bolus of 18F-fludarabine...

Culture negative endocarditis (CNE) is a common concern in patients with fever, heart murmur, cardiac vegetation, and negative blood cultures. The diagnosis of CNE is not based only on negative blood cultures and a cardiac vegetation. The clinical definition of CNE is based on negative blood cultures plus the findings of culture positive infective endocarditis (IE), e.g., fever, cardiac vegetation, splenomegaly, peripheral manifestations. Because embolic splenic infarcts may occur with culture positive IE, some may assume that splenic infarcts are a sign of CNE...

Hepatitis C virus (HCV) is a single-stranded RNA virus that not only affects hepatocytes, by B cells as well. It is thought that HCV is involved in the onset of B-cell lymphoma. The clinicopathological characteristics of HCV-positive diffuse large B-cell lymphoma (DLBCL) and HCV-positive splenic marginal zone lymphoma (SMZL) are known, but there has been no report on HCV-positive follicular lymphoma (FL). In this study, the clinicopathological characteristics of HCV-positive FL were examined in 263 patients with FL who were classified into a HCV-positive group with HCV antibody and negative groups without one...

Spontaneous splenic rupture is a quite rare entity that may develop secondary to some special situations (lymphoma, post-abdominal surgey etc). In the literature, the case of a patient has been reported following thoracic surgery. In a patient who had undergone right upper lobectomy for pulmonary carcinoma, signs of acute abdomen and low levels in the hemogram were detected on the fifth postoperative day; therefore, the patient underwent further investigations. A radiological evaluation revealed splenic rupture, and the patient was operated on...

RATIONALE: Primary angiosarcoma of the spleen (PAS) is a very rare malignant neoplasm that originates from endothelial cells of the splenic blood vessels. Without typical clinical presentations and specific radiological features, PAS is very difficult to be early identified and 1-year mortality is extremely high. Late detection and spleen rupture are considered as the most important risk factors for early metastasis. PATIENT CONCERNS: Without any obvious symptom, a 35-year-old woman was admitted with splenic neoplasm that was accidentally discovered through a routine physical examination...

RATIONALE: Hemophagocytic lymphohistiocytosis (HLH) occurs primarily in pediatric population, or secondary to malignancy, infection, or autoimmune disease. This disease is rare and prognosis is generally poor. Only a small number of cases during pregnancy have been reported in literature. PATIENT CONCERNS: We report a case of pregnancy-associated HLH secondary to natural killer (NK)/T cells lymphoma. She was admitted at 30 weeks and 3 days of pregnancy with complaints of abdominal pain and fever as high as 39...

There are exceedingly rare reports of patients with epidermotropic B-cell lymphomas. A subset presented with intermittent, variably pruritic papular eruptions and involvement of their spleens, peripheral blood, and bone marrow at the time of diagnosis. Furthermore, some experienced an indolent course despite dissemination of their lymphomas. We report a 66-year-old woman with a 12-year history of intermittent eruptions of nonpruritic salmon-colored papules on her torso and proximal extremities that occurred in winter and resolved with outdoor activity in spring...

Purpose To evaluate whether an incidentally noted splenic mass at abdominal computed tomography (CT) requires further imaging work-up. Materials and Methods In this institutional review board-approved HIPAA-compliant retrospective study, a search of a CT database was performed for patients with splenic masses at CT examinations of the abdomen and chest from 2002 to 2008. Patients were divided into three groups: group 1, patients with a history of malignancy; group 2, patients with symptoms such as weight loss, fever, or pain related to the left upper quadrant and epigastrium; and group 3, patients with incidental findings...

Intravascular lymphoma (IVL) is a rare subtype of diffuse large B-cell lymphoma characterized by a clonal proliferation of lymphocytes restricted to the intravascular space. We present the case of a 60-year-old man with hemophagocytic syndrome secondary to IVL. F-FDG PET/CT demonstrated hepatosplenomegaly with marked diffuse hepatic, splenic, and bone marrow hypermetabolism. The case report illustrates the imaging findings of this uncommon variant of IVL.

Radioimmunotherapies with monoclonal antibodies (mAbs) to the B-lymphocyte antigen 20 (CD20) are effective treatments for B-cell lymphomas, but United States Food and Drug Administration (FDA)-approved radioimmunotherapies exclusively use radiolabeled murine antibodies, potentially limiting re-dosing. The FDA recently approved two unlabeled anti-CD20 monoclonal antibodies, obinutizumab and ofatumumab, termed "next generation" as they are humanized (obinituzumab) or fully human (ofatumumab), thus potentially allowing a greater potential for re-dosing than with previous generation anti-CD20 antibodies, including rituximab (chimeric) and tositumumab (murine) which contain more murine peptide sequences...

Splenic marginal zone lymphomas (SMZLs) are rare indolent B cell neoplasms that affect the spleen, bone marrow, and blood. Although they have an indolent course in the majority of patients, who have a median survival of 8-10 years, ∼ 30% may experience a worse outcome. The prognostic criteria of progression are lymph node and extra-nodal involvement, high lymphocyte counts, anaemia, and thrombocytopenia. The treatment of SMZLs include a "wait and watch strategy", splenectomy, and alkylating agents ± rituximab...

Data on management of pediatric marginal zone lymphoma (MZL) are scarce. This retrospective study assessed characteristics and outcome in 66 patients who were <18 years old. Forty-four (67%) had an extranodal MZL (EMZL), 21 (32%) a nodal MZL (NMZL), and one patient a splenic MZL. Thirty-three patients (50%) received a variable combination of adjuvant chemotherapy/immunotherapy/radiotherapy, while the remainder, including 20 of 21 with NMZL, entered an active observation period. Overall survival was excellent (98 ± 2%), although 11 patients relapsed (17%; NMZL, n = 1; EMZL, n = 10), seven after any therapy and four after complete resection only...
