Primary intestinal T-cell lymphoma is a rare disease entity, which is approximately 10% to 25% of intestinal lymphomas, and most of the lymphomas occur in the small intestine. We report here a case of a 56-year-old woman who has been suffering from chronic diarrhea and weight loss for 6 months. Abdominal CT scan and small bowel series showed diffuse wall thickening of the small bowel. Gastrosco...
The development of gastric carcinoma in a patient with gastric lymphoma is rare. Helicobacter pylori is a common etiologic agent for both these conditions. We report a 38-year-old lady who was initially diagnosed to have gastric lymphoma and developed early gastric carcinoma on follow up. She was operated on for the carcinoma and is in complete remission since.
AIM To evaluate the role of surgical resection in the treatment of patients with primary gastrointestinal non-Hodgkin s lymphoma in our institution. METHOD The retrospective study included 79 patients with a histologically confirmed primary gastrointestinal lymphoma, who were diagnosed and treated for the disease in the 1978-1997 period. According to the treatment modality, the patients were ...
4Department of Pathology, Stanford University, Stanford, CA. xtranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue, or MALT lymphoma, is a non-Hodgkin’s lymphoma associated with chronic inflammation. It typically occurs in the gastric mucosa or the thyroid parenchyma, and is rarely reported in the breast [1]. Histologically, MALT lymphoma is characterized by heterogeneous...
Gastritis represents an inflammation of the stomach lining in response to injury. It is either acute or chronic, and has many underlying causes which can be diagnosed and classified histologically where endoscopic appearances such as redness are often misleading. Gastritis is seldom if ever symptomatic, but usually have important clinical sequelae, principally duodenal and gastric ulceration, g...
BACKGROUND Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is associated with Helicobacter pylori infection and H. pylori eradication is used as its first-line therapy. However, controversies exist about the prognostic value of H. pylori infection in these patients. We evaluated the prognostic impact of H. pylori infection and eradication therapy in gastric MALT lymphoma. METHODS A ...
Marginal zone lymphomas have been associated with several infectious agents covering both viral and bacterial pathogens and in some cases a clear aetiological role has been established. Pathogenetic mechanisms are currently not completely understood. However, the role of chronic stimulation of the host immune response with persistent lymphocyte activation represents the most convincing explanat...
BACKGROUND The aim was to examine characteristics and treatment results of patients with mucosa-associated lymphoid tissue (MALT) non-Hodgkin's lymphomas. PATIENTS AND METHODS Epidemiological and clinical features of 97 patients with MALT lymphoma from the Hellenic Cooperative Oncology Group registry were analysed retrospectively for their prognostic significance in progression-free survival ...
Extranodal marginal zone lymphomas of mucosa-associated lymphoid tissue (MALT) type represent 7-8% of all B cell lymphomas and up to 50% of primary gastric lymphomas and can arise at any extranodal site. The most common manifestation is the stomach, which is almost invariably associated with a chronic Helicobacter pylori infection. The diagnosis is based on the histopathological evaluation of m...
Editorial Individuality versus conformity. Is perfection necessary in staging and prognostic classifications of specific primary extranodal lymphomas? "Perfection is I he enemy of the good." Voltaire The two papers in this issue that address the management of primary gastric lymphoma have more in common than does the disease under discussion. Both consider questions surrounding the management o...
