The indolent and favorable clinical course of extranodal B cell lymphoma of mucosa-associated lymphoid tissue type (MALT lymphoma) of stomach is well known. For both physician and patient, one of the most fearful parts for gastric MALT lymphoma must be the bone marrow aspiration and biopsy (BMAB) rather than the disease itself. Guidelines from authorities still does not reach to a concurrence o...

It seems very interesting and also strange that a malignant disease can be treated with antibiotics and acid suppressant combination therapy, rather than chemotherapy or radiotherapy. Infectious agents such as hepatitis B virus and hepatitis C virus, Epstein-Barr virus, Helicobacter pylori, and herpes simplex virus are well known causative agents for chronic inflammation associated cancers incl...

Primary gastric lymphoma (PGL) is the most common type of extranodal that originates from lymphatic tissue within submucosa. In past two decades, treatment PGL has been overturned surgery to non-surgical individualized treatment, and its prognosis are different those other malignant lesions in stomach, so early diagnosis, accurate staging, timely monitoring outcome extremely important. Unlike i...

A 36-year-old Japanese woman presented with extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) in the stomach. The gastric lesions only partially improved after eradication therapy for Helicobacter pylori. A fluorescence in situ hybridization analysis revealed no fusion genes of API2-MALT1, although trisomy of chromosome 18 was identified. Radiation therapy w...

inflammatory myopathy is a paraneoplastic syndrome. inflammatory myopathy may be the first manifestation of underlying malignancy. it was reported in patients with colon cancer, breast cancer, ovarian cancer, lung cancer and non-hodgkin lymphoma. there are few reports regarding inflammatory myopathy in patients with gastric cancer. we want to present inflammatory myopathy as early manifestation...

Immunoproliferative small intestinal disease (originally called Mediterranean lymphoma and subsequently alpha chain disease) is a slowly progressive low grade primary small intestinal B-cell lymphoma characterized by the synthesis of a truncated alpha heavy chain without light chain by the neoplastic cells. The histological features of IPSID and low grade primary gastric B-cell lymphoma are clo...

A series of primary gastric lymphomas and adenocarcinomas was reviewed to assess the prevalence of lymphocytic gastritis in these conditions. Lymphocytic gastritis was more prevalent in patients with gastric adenocarcinoma (16 of 130 cases; 12.3%) and primary gastric lymphoma (six of 45 cases; 13.7%) than in unselected patients undergoing endoscopy (0.83-2.5%). This suggests that these two disp...

Primary gastric lymphoma, an uncommon gastric tumor caused by infection with Helicobacter pylori, is rarely associated with gastric amyloidosis. Chronic bacterial infection is known to cause amyloidosis. We report a 53-year-old man who had an antral and duodenal mass with narrowing and ulceration on endoscopy and CT scan; endoscopic biopsy revealed gastric amyloidosis. Rapid urease test and ser...

A 75-year-old female, who had an abnormal stomach x-ray finding, was admitted to the hospital for further examination and therapy. Upper GI endoscopy showed reddish and swollen folds on the greater curvature of the gastric body and a biopsy was of this lesion revealed malignant lymphoma (small cell type or mucosa-associated lymphoid tissue (MALT) lymphoma suspected). The patient was infected wi...

BACKGROUND Various histological classifications developed for nodal lymphomas failed to be of value in extranodal lymphomas. More recently, gastric lymphoma is considered to represent a distinctive group derived from mucosa associated lymphoid tissue (MALT). AIM To study the prognostic value of malignancy grading based on the concept that most gastric lymphomas are of MALT origin, the endosco...
