PET-CT with somatostatin analogs labeled with Ga is increasingly recognized as the best imaging modality for the evaluation of well-differentiated neuroendocrine tumors (NETs). However, somatostatin receptor (SSR) is not an exclusive marker for NET. A variety of tumors other than NETs express SSR, leading to a significant risk of false-positive PET/CT results. We illustrate false-positive Ga-DOTATATE PET/CT findings due to high uptake by non-Hodgkin lymphoma, metastatic meningioma, breast cancer, thyroid adenoma, and papillary carcinoma...

AIMS: Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL), not otherwise specified (NOS) is defined as monoclonal EBV(+) B-cell proliferation affecting patients without any known immunosuppression. Non-neoplastic EBV(+) cells proliferating in or adjacent to EBV(-) DLBCL were reported recently, but their clinical significance is unclear. Thus, we investigated the prognostic impact of EBV(+) cells in DLBCL. METHODS AND RESULTS: We compared the clinico-pathological characteristics of 30 EBV(+) DLBCL patients and 29 and 604 EBV(-) DLBCL patients with and without EBV(+) bystander cells (median age of onset 71, 67, and 62 years, respectively)...

RATIONALE: The occurrence of primary cutaneous diffuse large B cell lymphoma-other (PCDLBCL-O) has been rarely reported in the literature. Its diagnosis is based on histopathological and immunohistochemical examinations. To improve the clinical diagnosis and treatment for PCDLBCL-O, we report a case of PCDLBCL-O successfully treated by the combination of R-CHOP (A chemotherapy protocol consists of cyclophosphamide, doxorubicin, vincristine, prednisone plus Rituximab) chemotherapy and surgery...

PURPOSE: Primary bone lymphoma (PBL) is one of the rarest primary bone malignancies. Very limited data are available on the role of fluorine-18-fluorodeoxyglucose (F-FDG) PET/CT in PBL. PATIENTS AND METHODS: Overall, 16 relevant patients had F-FDG PET/CT for staging or staging/restaging PBL. The cases with extraskeletal lesions such as lymphadenopathy or with osseous involvements in disseminated lymphoma were excluded on the basis of the definition of PBL. F-FDG PET/CT findings were correlated to pathologic and/or anatomic image information...

Interleukin-32 (IL-32) is a novel cytokine involved in inflammation and cancer development. IL-32 gene consists of eight small exons, and IL-32 mRNA has nine alternative spliced isoforms, and was thought to be secreted because it contains an internal signal sequence and lacks a transmembrane region. IL-32 is initially expressed selectively in activated T cells by mitogen and activated NK cells and their expression is strongly augmented by microbes, mitogens, and other cytokines. The IL-32 is induced mainly by pathogens and pro-inflammatory cytokines, but IL-32 is more prominent in immune cells than in non-immune tissues...

We have previously reported on life span shortening as well as increased incidence rates in several neoplasms in B6C3F1 mice that were continuously exposed to 21 mGy/day of gamma rays for 400 days. To clarify whether the life shortening was due to early appearance of neoplasms (shortened latency) or increased promotion/progression, 8-week-old female specific-pathogen-free B6C3F1 mice were gamma-ray irradiated at a low dose rate of 20 mGy/day for 400 days. At 100 days postirradiation, 60-90 mice were sacrificed, and thereafter every 100 days alongside the age-matched nonirradiated controls, for 700 days...

The presence of inflammation and demyelination in a central nervous system (CNS) biopsy points towards a limited, yet heterogeneous group of pathologies, of which multiple sclerosis (MS) represents one of the principal considerations. Inflammatory demyelination has also been reported in patients with clinically suspected primary central nervous system lymphoma (PCNSL), especially when steroids had been administered prior to biopsy acquisition. The histopathological changes induced by corticosteroid treatment can range from mild reduction to complete disappearance of lymphoma cells...

Primary gastrointestinal (GI) lymphoma is a heterogeneous disease with varied clinical presentations. The stomach is the most common GI site and accounts for 70% to 75% of GI lymphomas. We present a patient with gastric diffuse large B cell lymphoma (DLBCL) who presented with significant weight loss, early satiety, and multifocal ulcerated gastric lesions. Esophagoduodenoscopy should be performed in patients presenting with warning symptoms as in our case. Diagnosis is usually made by endoscopic biopsies. Multiple treatment modalities including surgery, radiotherapy, and chemotherapy have been used...

Composite lymphoma (CL) is a rare disease with 2 distinct lymphomas concurrently arising in a single patient with an estimated incidence of 1-4.7% of newly diagnosed lymphomas per year. CL most commonly involves 2 B-cell non-Hodgkin lymphomas (NHL) or a B-cell NHL with a Hodgkin lymphoma. Our case is unique in that it was a bilineage CL with both a T-cell and B-cell NHL, which has only been reported in a few case reports. A 49-year-old woman presented with several months of progressive cough, weight loss, dyspnea, and supraclavicular lymphadenopathy...

BACKGROUND: Due to the uncommon nature of primary spinal epidural lymphomas (PSELs), there has been little research looking at prognostic indicators for the tumor. To our knowledge, this is the largest study to evaluate possible clinical and pathologic prognostic factors in PSEL patients. METHODS: We retrospectively reviewed 130 cases of PSEL, including 36 Chinese patients and 94 published case reports from 1985 to 2015. Patient treatment regimens included surgery (S; n = 119), surgery followed by chemotherapy (S + CT; n = 25), surgery followed by radiotherapy (S + RT; n = 26), and surgery followed by chemotherapy and radiotherapy (S + CT + RT; n = 50)...

: To identify prognostic factors for patients with diffuse large B-cell lymphoma (DLBCL), specifically those classified into conflicting subgroups by Hans' and Choi's classification algorithms. We retrospectively reviewed clinical and pathological data of 154 patients diagnosed with de novo DLBCL in the First Hospital of Jilin University from January 2004 to September 2011. All cases were classified into subgroups based on Hans' and Choi's algorithms with immunohistochemical markers. STATISTICAL ANALYSIS USED: The correlation between various clinicopathological factors and 5-year survival rate, the correlation between those factors with the International Prognostic Index, the concordance between Hans' and Choi's approach was evaluated...

BACKGROUND: There is a growing body of evidence indicating that pediatric survivors of cancer are at a greater risk of developing metabolic syndrome. This study evaluated some probable predictors of metabolic syndrome (MS), such as leptin and adiponectin concentrations, the leptin/adiponectin ratio, insulin resistance, and adiposity, in a sample of child survivors of lymphoma and leukemia in Mexico City. METHODS: Fifty two children (leukemia n = 26, lymphoma n = 26), who were within the first 5 years after cessation of therapy, were considered as eligible to participate in the study...

Composite lymphomas (CLs) are defined as two unrelated lymphomas occurring at the same time within the same tissue. The incidence of these tumors is low. Of all possible combinations between lymphomas, the least frequent are the ones combining peripheral T-cell lymphoma (PTCL) and Hodgkin lymphoma (HL). We recently identified five cases of CL composed of PTCL and classical HL, mixed cellularity type. We investigated histological and clinical features of these cases. Immunostaining was performed on paraffin sections...

Composite lymphoma is an extremely rare clinical entity and is characterized by the presence of two different subtypes of lymphoma in the same lymph node. We report a case of composite lymphoma in a 57-year-old male presenting with leg and groin pain. The right inguinal lymph node biopsy showed large and small cells. Immunohistochemistry was consistent with large cells staining for diffuse large B-cell lymphoma (DLBCL) and small cells positive for mantle cell lymphoma (MCL). Polymerase chain reaction (PCR) analysis of immunoglobulin heavy (IGH) chain and immunoglobulin kappa (IGK) light chain gene rearrangements confirmed that the two were clonally unrelated neoplasms...

Collecting duct carcinoma (CDC) and related tumors [ie, renal medullary carcinoma (RMC)] are rare types of highly aggressive renal cell carcinomas (RCC) with poor prognosis. Because of the rarity and diagnostic uncertainty of them, their molecular pathology and significance have not yet been fully elucidated. CDC, RMC, fumarate hydratase-deficient RCC (including hereditary leiomyomatosis and RCC-associated RCC HLRCC-RCC), and recently reported anaplastic lymphoma kinase (ALK)-rearrangement RCC have significant morphologic overlaps, but they are separately distinct entities having different molecular pathway and clinical settings...
