Background and aims. Helicobacter pylori is a microaerophilic gram-negative spiral organism. It is recognized as the etiologic factor for peptic ulcers, gastric adenocarcinoma and gastric lymphoma. Recently, it has been isolated from dental plaque and the dorsum of the tongue. This study was designed to assess the association between H. pylori and oral lesions such as ulcerative/inflammatory le...

non-hodgkin lymphoma (nhl) is one of the masquerade syndromes of malignant melanoma that can occur with two main patterns of presentations in the eye: metastatic involvement of uveal tract, and primary involvement of retina. we report ophthalmic, imaging and histopathological findings in the first case diagnosed as primary choroidal nhl without central nervous system or systemic involvement. a ...

we report a case of a. naeslundii bacteremia in an 11 year-old boy with persistent fever for two weeks prior hospital admission. he was finally diagnosed with malignant t cell lymphoma. isolation of this bacterium from the blood culture of our patient can serve as an important warning indicating that incuriosity about fastidious and not easily grown bacteria isolated from clinical samples may l...

Central nervous system dissemination is a relatively uncommon but almost always fatal complication in diffuse large B-cell lymphoma patients. Optimal therapy for central nervous involvement in this malignancy has not been established. In this paper, we aimed to evaluate the therapeutic effect of E7123, a celecoxib derivative that inhibits focal adhesion signaling, in a novel xenograft model of ...

Mucosa-Associated Lymphoid Tissue (MALT) lymphoma also referred to as extranodal marginal zone B-cell lymphoma, is rare in the oral soft tissue [1-8]. Primary MALT lymphomas are most commonly seen in the gastrointestinal tract [1,2,4]. Within the oral soft tissue, the salivary glands are the most affected with the parotid gland being the most common site [9] and the minor salivary glands being ...

BACKGROUND Lymphoma of the mucosa associated lymphoid tissue (MALT) arising in the stomach has been shown to be related to Helicobacter pylori infection, and total regression of gastric lymphoma after successful eradication of H pylori has consistently been reported. MALT-type lymphoma at other localisations, however, has to our knowledge not been linked to H pylori, and eradication of the bact...

BACKGROUND Iron is essential for cell proliferation and viability. It has been reported that iron depletion by a chelator inhibits proliferation of some cancer cells. Deferasirox is a new oral iron chelator, and a few reports have described its effects on lymphoma cells. The goal of this study was to determine the anticancer effects of deferasirox in malignant lymphoma cell lines. METHODS Thr...

Lymphomas of the oral cavity represent 5% of all lymphomas. They usually occur in immunocompromised patients. Lymphoma arising within a single bone, without visceral or lymph node involvement, is known as primary intraosseous lymphoma. It is a rare condition and constitutes 3.1% of malignant bone tumors and 5% of extranodal lymphomas. Primary lymphoma of the jaw is seldom seen and it is often m...

Unlike typical hydroa vacciniforme (HV), Epstein-Barr virus (EBV)-associated HV-like eruption is more variable in its clinical manifestations. In some patients, progression to lymphoma or leukemia has been reported, which are characterized by the T-cell immunophenotype. Here, we report the first Korean case of EBV-associated vesiculopapular eruption on the face of a patient with natural killer ...
