Helicobacter pylori infection is the major cause for mucosa-associated lymphoid tissue (MALT) lymphoma and gastric cancers. On the other hand, gastric cancers are known to arise from gastric mucosal atrophy. We here report a case of signet ring cell gastric cancer that developed after radiation therapy for MALT lymphoma in H. pylori-uninfected patient whose stomach did not show gastric mucosal ...

Non-Hodgkin lymphoma usually arises from lymphoid or nodal tissue, and can occasionally involve other sites. Extra-nodal marginal-zone B-cell lymphoma of mucosaassociated lymphoid tissue (MALT lymphoma) is uncommon and constitutes around 8% of all non-Hodgkin lymphomas. Most MALT lymphomas are of gastric origin and lung involvement is rare. Primary pulmonary lymphoma is defined as clonal lympho...

Note The vast majority of both benign and malignant tumours of the stomach are of epithelial origin, with mesenchymal and neuroendocrine tumours being much less common. Gastric adenocarcinoma comprises in excess of 95% of malignant neoplasms of the stomach, and is thus the focus of this overview. Primary gastric lymphoma is the second commonest malignancy affecting the stomach with gastrointest...

Doubtless, the knowledge about the pathogenesis of primary gastric lymphoma could be improved during the last decade. This knowledge is based, above all on histomorphological, experimental and epidemiological investigations which demonstrated that Helicobacter pylori infection plays the important role in developing gastric MALT lymphoma [1]. Nevertheless, the management of this disease remains ...

PURPOSE The pathogenesis and clinical heterogeneity of gastric diffuse large B-cell lymphoma (DLBCL) are poorly understood. We have comprehensively investigated the incidence and clinical significance of lymphoma-associated chromosomal translocations, particularly those involving the immunoglobulin heavy chain (IGH) gene locus, in a large series of gastric DLBCL. EXPERIMENTAL DESIGN One hundr...

Small bowel lymphomas of the extranodal type occur in the young and are characteristically associated with malabsorption syndrome. We present the case of an elderly in whom there was no malabsorption and the duodenal tumor was a gastric type marginal zone B cell lymphoma also known as gastric mucosa-associated lymphoid tissue (MALT) lymphoma. A 73-year-old woman presented to the emergency room ...

primary cardiac lymphoma is a rare disease which mainly found in elderly men. it is usually a b-cell non-hodgkin’s lymphoma which primarily located in the heart and may involve the pericardium. the common presentations include massive pericardial effusion and heart failure. clinical diagnosis is often delayed in these patients and prognosis is dismal. we report a case of a 70-year-old man prese...

esophageal lymphoma is a rare condition, accounting for less than 1% of all gastrointestinal lymphomas. primary extra nodal esophageal lymphoma constitutes less than 0.2% cases of the total esophageal lymphomas. the definition of primary gi lymphoma has differed among authors. the etiology of the disease is unknown, with the role of epstein-barr virus being controversial. the common symptoms of...
