The authors present a retrospective analysis of follicular lymphomas (FL) and mantle cell lymphomas (MCL) diagnosed according to the WHO classification (2008) in consecutive biopsies of GI organs in a period of 11 years. The series includes 18 patients with FL verified in 22 biopsies and 44 patients with MCL diagnosed in 54 biopsies. FL represented always a solitary tumor, most often - up to ¾ of all the cases - of a small intestine, more often in its jejunoileal than duodenal parts. The biopsies were obtained almost equally by endoscopical approach, they were usually mucosal and rarely polypectomic, as well as by surgical resections (54,5 % and 45,5 % of the cases respectively)...

PURPOSE: Radionuclide therapy (RNT) is a rapidly growing area of clinical nuclear medicine, wherein radionuclides are employed to deliver cytotoxic dose of radiation to the diseased cells/tissues. During RNT, radionuclides are either directly administered or delivered through biomolecules targeting the diseased site. RNT has been clinically used for diverse range of diseases including cancer, which is the focus of the review. CONCLUSIONS: The major emphasis in RNT has so far been given towards developing peptides/antibodies and other molecules to conjugate a variety of therapeutic radioisotopes for improved targeting/delivery of radiation dose to the tumor cells...

Mantle cell lymphoma (MCL) is a rare malignant lymphoma of the gastrointestinal (GI) tract that may present as multiple lymphomatous polyposis (MLP); however, MLP with intussusception is rarely reported in MCL. In the present study, a 54-year-old male patient was diagnosed with MCL, presenting with numerous polypoid lesions of the complete GI tract combined with ileocecal intussusception. Right hemicolectomy was performed in order to prevent complicated intussusception and for tumor debulking. In addition, 6 cycles of chemotherapy were performed with the rituximab plus hyper-CVAD regimen...

Gastrointestinal lymphomas represent up to 10% of gastrointestinal malignancies and about one third of non-Hodgkin lymphomas. The most prominent histologies are mucosa-associated lymphoid tissue lymphoma and diffuse large B-cell lymphoma. However, the gastrointestinal tract can be the site of rarer lymphoma subtypes as a primary or secondary localization. Due to their rarity and the multifaceted histology, an endoscopic classification has not been validated yet. This review aims to analyze the endoscopic presentation of rare gastrointestinal lymphomas from disease diagnosis to follow-up, according to the involved site and lymphoma subtype...

Mantle cell lymphoma (MCL) accounts for approximately 6% of all non-Hodgkin lymphomas (NHLs). The median age at diagnosis is 60 to 70 years, although MCL may occur in younger patients. Between 75% and 80% of patients are males. MCL usually presents as stage III/IV disease, and extranodal involvement is quite common, particularly in the bone marrow, blood, and gastrointestinal tract. Until recently, MCL was considered a disease with an overall poor prognosis. With the introduction of more aggressive induction chemotherapy regimens (especially those incorporating high-dose cytarabine), the anti-CD20 monoclonal antibody rituximab, and the more widespread use of consolidation with high-dose therapy and autologous stem cell rescue, outcomes have significantly improved...

Gastrointestinal (GI) lymphoma encompasses a heterogeneous group of neoplasms that have a common lymphoid origin but variable pathologic and imaging features. Extranodal marginal zone B-cell lymphoma (ENMZL) and diffuse large B-cell lymphoma (DLBCL) are the most common. ENMZL usually occurs in the stomach, where it is associated with chronic infection by Helicobacter pylori, and is typically a superficial spreading lesion that causes mucosal nodularity or ulceration and mild wall thickening. DLBCL may arise de novo or from transformation of ENMZL or other low-grade lymphomas...

Non-Hodgkin's lymphomas (NHL) are an important variety of gastrointestinal tumors with increasing incidence and prevalence. Traditional management of NHL with chemotherapy is challenging and expanding evidence points to significant tumor response to radiation therapy (RT). However, there exists a wide range of radiation-related toxicities. Optimization of exact tumor marking coupled with minimization of the radius of radiation delivery is essential to increase patient's tolerance and decrease side effects of the treatment...

There are no "benign lymphomas", a fact due to the nature of lymphoid cells to circulate and home as part of their normal function. Thus, benign clonal expansions of lymphocytes are only rarely recognized when localized. Recent studies have identified a number of lymphoid proliferations that lie at the interface between benign and malignant. Some of these are clonal proliferations that carry many of the molecular hallmarks of their malignant counterparts, such as BCL2/IGH and CCND1/IGH translocations associated with the in situ forms of follicular lymphoma and mantle cell lymphoma, respectively...

We present seven cases of mantle cell lymphoma with morphological features of marginal-zone lymphoma. Of particular interest, four of the patients had predominant involvement of the gastrointestinal tract. All cases displayed the translocation t(11;14)(q13;q32) and expressed cyclin D1. Cytogenetic analysis revealed trisomy 3 in one case and somatic hypermutation of immunoglobulin heavy genes could be demonstrated in two out of four cases. The latter features are reminiscent of marginal-zone lymphoma. The localization of these lymphomas mainly in the gastrointestinal tract and the higher exposure to antigens in this area may explain why this variant of mantle cell lymphoma harbours features of marginal-zone lymphoma...

BACKGROUND: The causes of anemia in infrequent blood donors deferred for low hemoglobin (Hb) are not well known. We sought to assess this via surveys of infrequent, non-menstruating deferred blood donors at two institutions, BloodCenter of Wisconsin and Puget Sound Blood Center. STUDY DESIGN AND METHODS: Men at least 18 years of age and women at least 50 years of age who were deferred for low Hb (≤12.5 g/dL), had not more than one donation in the year prior to deferral, and did not successfully donate in the 3 months after their deferral were surveyed...

INTRODUCTION: The advent of small bowel capsule endoscopy (CE) has greatly improved the diagnosis of small bowel tumours. Double balloon enteroscopy (DBE) is the interventional counterpart to CE and has the advantage of direct visualisation of small bowel pathology, biopsy and therapeutic capability. There is however a paucity of data on the use of DBE for small bowel tumours. The aim of this study was to assess the utility of DBE for small bowel tumours and to assess its impact on the diagnostic pathway in this cohort...

Mantle cell lymphoma (MCL) is a mature B-cell non-Hodgkin lymphoma. After the (11;14) translocation was identified as its constant finding in 1992, MCL was recognized as a separate subgroup of non-Hodgkin lymphoma (NHL). In MCL, extranodal involvement may be observed in the bone marrow, the spleen, the liver, and the gastrointestinal system (GIS). Cases of MCL that present with a massive and solitary rectal mass are rare in the literature. In this case report, our aim was to present an MCL patient with a rarely observed solitary rectal involvement mimicking rectal carcinoma and to discuss treatment options for this patient...

Multiple lymphomatous polyposis (MLP) is an uncommon type of gastrointestinal lymphoma characterized by the presence of multiple polyps along the gastrointestinal tract. Most of this entity is in fact considered the counterpart of gastrointestinal tract involvement for mantle cell lymphoma (MCL). To our knowledge, there have been no reports on [fluorine-18]-fluorodeoxy-glucose ((18)F-FDG)-positron emission tomography (PET)/computed tomography (CT) imaging for gastrointestinal MCL with MLP. We present the results of (18)F-FDG PET/CT imaging in a patient with gastrointestinal tract involvement of MCL showing continuous MLP from the stomach to the rectum and intestinal intussusception...
