primary non-hodgkin’s lymphoma of the cranial vault is extremely rare. this case report presents a 42-year-old man with a painless subcutaneous scalp mass which extended intracranially associated with recent mild headache. initial computed tomography and magnetic resonance imaging revealed two lesions emanating from the skull. biopsy revealed a diagnosis of diffuse large b cell lymphoma (dlbcl)...

The authors describe a case of histiocyte-rich B-cell lymphoma (HR-BCL), a variant of diffuse large B-cell lymphoma, in a 51-year-old man. The patient presented with large axillary lymphadenopathy. Histopathologic and immunohistochemical examination of lymph node biopsy revealed diffuse effacement of the lymph node architecture by reactive histiocytes and neoplastic CD20 positive B cells. ...

introduction: primary gastric lymphoma (pgl) is a rare tumor, whose differential diagnosis may become complicated without precise immunohistochemistry (ihc) and genetic analysis. case presentation: a 33-year-old woman presented with gastric cancer and had undergone gastrectomy without precise ihc and staging in another center. inappropriate ihc after surgery showed diffuse large b-cell lymphoma...

background and objectives: epstein barr virus (ebv) is one of the members of herpesviridae family and a sub-category of gamma herpes virinae. ebv, which normally has cr2 or cd21 receptors on b-lymphocytes, has mutagenic features for them. the virus plays an important role in causing some malignant cancers. about 30% of the cases with non-hodgkin’s lymphoma are diffuse large b-cell lymphoma (dlb...

Introduction: This study is aimed to assess the prevalence and characteristics of head and neck lymphoma in a defined group of an Iranian population.   Materials and Methods: In this retrospective study, 126,450 biopsy reports from two referral Pathology Departments, (Tehran, the capital of Iran) were evaluated. In cases with head and neck lymphoma, other variables such as age, sex, specific lo...

We describe some modelling and reconstruction methods for optical imaging in the macroscopic and mesoscopic regimes. Beginning with the basic model of radiative transport, we describe the diffusion approximation and its extensions. Some linear and nonlinear problems in diffuse optical imaging are outlined, together with some indications of current trends and future directions.

I review the status of the model of dark matter as the neutralino of supersymmetry in the light of constraints on supersymmetry given by the 7- to 8-TeV data from the Large Hadron Collider (LHC).

We point out that vector boson fusion at the Large Hadron Collider (LHC) can lead to useful signals for charginos and neutralinos in supersymmetric scenarios where these particles are almost invisible. The proposed signals are just two forward jets with missing transverse energy. It is shown that, in this way, one can put by far the strongest constraint on the parameter space of a theory with a...
