A 41-year-old woman presented with abdominal distention, inappetence, and rapid emaciation for 1 month. Diffuse bulky gastric wall thickening with lymph nodes enlargement and peritoneal nodules were revealed using abdominal CT. Staging F-FDG PET/CT performed after admission demonstrated intensely diffuse FDG uptake in stomach, FDG-avid lymph nodes, and peritoneal nodular lesions. Postoperatively, these lesions were diagnosed as diffuse large B-cell lymphoma.

Iron overload is a major complication in blood transfusion procedures. This report presents a case of malignant lymphoma, in which the findings of bone marrow involvement were discordant between F-FDG PET imaging studies and MRI with diffusion-weighted imaging studies. In this case, the PET imaging studies were positive for malignant lymphoma, whereas the MRI studies were negative. Iron deposition in the reticuloendothelial system due to posttransfusion iron overload was considered to be the cause of the decrease in signal intensity on diffusion-weighted imaging, resulting in a false-negative finding on MRI...

Nodular lymphoid hyperplasia (NLH) is a rare benign condition that is characterized by diffuse hyperplasia of the lymphoid follicles of the gastrointestinal tract (GIT). During endoscopy, NLH appears as multiple or occasionally innumerable nodules measuring a few millimeters in diameter. NLH occurs mainly in the small intestine, less commonly in the large intestine and rarely involves the stomach. There are multiple associated diseases such as immunoglobulin deficiency syndromes, giardiasis, Helicobacter pylori (H...

Background: Secondary central nervous system lymphoma (SCNSL) is a rare and aggressive disease, which is defined as secondary central nervous system (CNS) involvement in patients with systemic lymphoma. According to previous reports, SCNSL presents mostly with leptomeningeal spread; however, our experience differs. In the present study, we demonstrate the diversity of magnetic resonance imaging (MRI) patterns in SCNSL. Patients and methods: Initial morphological MRI findings in 21 patients (10 women and 11 men with mean age 62...

BACKGROUND: Leptomeningeal metastasis is an uncommon but devastating complication. The incidence of non-Hodgkin's lymphoma has been increasing in recent decades, due to the poor central nervous system penetration of drugs and the prolonged overall survival of patients, leptomeningeal metastases has gradually increased over time. Patients with leptomeningeal metastases have short survival durations and poor quality of life; there are few studies about non-Hodgkin's lymphoma with leptomeningeal metastases...

Duodenal metastasis from renal cell carcinoma (RCC) is rare. The current case report presents a very rare case of late duodenal metastasis from RCC with newly developed malignant lymphoma (diffuse large B-cell lymphoma: DLBCL) at the same time. A 64-year-old man with systemic lymph nodes swelling who had undergone left nephrectomy for RCC 25 years previously, was admitted to the present hospital. Inguinal lymph node biopsy was performed, leading to a diagnosis of DLBCL. fluorine-18-fluorodeoxy-glucose (18 F-FDG)-positron emission tomography (PET)/computed tomography (CT) revealed multiple lymph nodes, spleen, and ileocecal lesions...

Primary non-Hodgkin's lymphoma (NHL) of the vagina is uncommon. The present case study reports the case of a 54-year-old female with a palpable mass between the rectum and vagina. The patient presented with symptoms consistent with vaginal cancer but lacked any of the 'B' symptoms often associated with systemic lymphoma, including fever, weight loss, night sweats and fatigue. The mass was resected under anesthesia. Immunohistochemistry and biopsy confirmed diffuse large B-cell NHL (DLBCL). Following surgery, six cycles of chemotherapy with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone were administered...

Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) is a subtype of nonclassical Hodgkin lymphoma (HL). It resembles non-Hodgkin lymphoma (NHL), by expressing classic B cell markers such as CD20 and CD79a however lacks definitive HL markers (such as CD15 and CD30). T cell histiocyte-rich large B cell lymphoma (THRLBCL), on the other hand, is a distinct entity classified under NHL and considered a variant of diffuse large B cell lymphoma (DLBCL). NLPHL can look morphologically and immunologically similar to THRLBCL and often poses a diagnostic challenge...

IL-6 is critical for tumorigenesis. However, previous studies on the association of IL-6 promoter polymorphisms with predisposition to different cancer types are somewhat contradictory. Therefore, we performed this meta-analysis regarding the relationship between IL-6 promoter single nucleotide polymorphisms and cancer susceptibility and prognosis. Up to April 2017, 97 original publications were identified covering three IL-6 promoter SNPs. Our results showed statistically significant association between IL-6 promoter and cancer risk and prognosis...

The objective of the present study was to evaluate the prognostic values of platelet count (PLT) and platelet to lymphocyte ratio (PLR) in diffuse large B-cell lymphoma (DLBCL), creating a novel prognostic scoring system. A total of 309 patients with newly diagnosed DLBCL were retrospectively analyzed. Receiver operating characteristic analysis was used to determine the optimal threshold values for PLT and PLR, which were 250×109 /l and 170, respectively. The patients with PLT ≥250×109 /l and PLR ≥170 experienced significantly decreased overall survival (OS) (P<0...

BACKGROUND: The International Prognostic Index (IPI) scoring system is the most widely used prognostic tool for diffuse large B-cell lymphoma (DLBCL); however, it fails to consistently identify patients with poor outcomes. This retrospective study was undertaken to confirm the clinical value of a new prognostic score and compare it with the IPI. METHODS: The aim of this single-center study was to confirm the clinical value of a new prognostic score and its association with various clinical features, disease progression, and death in 70 patients with DLBCL who had undergone at least 6 cycles of chemotherapy...

BACKGROUND: Patients with relapsed or refractory lymphoma or chronic lymphocytic leukaemia have a poor prognosis. Therapies targeting more than one isoform of PI3K, as well as mTOR, might increase antitumour activity. We aimed to investigate the efficacy and safety of voxtalisib (also known as XL765 or SAR245409), a pan-PI3K/mTOR inhibitor, in patients with relapsed or refractory lymphoma, or chronic lymphocytic leukaemia/small lymphocytic lymphoma. METHODS: We did a non-randomised, open-label, phase 2 trial at 30 oncology clinics in the USA, Belgium, Germany, France, the Netherlands, and Australia...

Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous diagnostic category with different molecular subtypes defined by distinct gene expression patterns and divergent mechanisms of oncogenic activation. Several studies have suggested an inferior survival for patients of the activated B-cell-like (ABC) versus the germinal center B-cell-like (GCB) DLBCL subtype which has led to increasing interest in investigating pharmacological inhibition of signaling pathways which contribute to lymphomagenesis and that are specifically utilized by ABC DLBCL cells...

Primary bone lymphoma is a rare disease, accounting for less than 5% of all extranodal lymphoma. Although the femur is cited as being the most common site, primary bone lymphoma is rare, accounting for less than 1% of all non-Hodgkin's lymphoma. Herein we present a case of diffuse B-cell-type malignant lymphoma manifested as a large soft-tissue mass of the leg, via metastasis of primary non-Hodgkin's lymphoma of the femur, which went untreated. We highlight the advantages of various imaging modalities used throughout the process of diagnosis and treatment because accurate and early diagnosis are essential...

A 49-year-old man was admitted to our hospital with pancreatitis. He was diagnosed with systemic lupus erythematosus at 34 years of age and was being treated with oral tacrolimus (3 mg/day) and predonine (10 mg/day) for the past 15 months. The computed tomography (CT) scan showed the mass lesion had invaded the pancreatic head via thickening of the duodenal wall. Upper gastrointestinal endoscopy showed the all-round ulcerative lesion from the superior duodenal angle to the descending portion. Histological examination confirmed the diagnosis of diffuse large B cell lymphoma (DLBCL)...
