Nowadays, it is believed that the main role in the development of gastric mucosa-associated lymphoid tissue (MALT) lymphoma plays Helicobacter pylori infection. This world-wide distributed bacteria is in charge of most cases of not only upper gastrointestinal tract disorders but also some of extragastric problems. Constant stimulation of the immune system causes a B-lymphocytes proliferation, w...
BACKGROUND/AIMS The aim of this study was to investigate the frequency of disseminated gastric mucosa-associated lymphoid tissue (MALT) lymphoma and the role of bone marrow study in the initial staging work-up. METHODS A total of 194 patients with gastric MALT lymphoma was enrolled. The incidence of disseminated disease was evaluated in the initial staging work-up. The demographic data and tu...
The aim of this study was to observe the histological features of chronic gastritis and associated effects due to Helicobacter pylori infection in 176 randomly selected antral biopsy specimens of chronic gastritis cases. The specimens were reviewed for the presence or absence of H.pylori. The activity (neutrophilic infiltration) of gastritis and the presence or absence of mucosa-associated lymp...
To clarify the clinicopathological findings of B-cell lymphoma associated with Sjögren’s syndrome (SJS) among Japanese Patients, 15 individuals with this disease were studied. The patients, 14 females and one male, ranged in age from 41 to 73 years with a median age of 56 years. These lymphomas arose not only in the salivary gland (n=4) but also in other mucosal extranodal sites (n=5). Histolog...
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 ...
Mucosa-associated lymphoid tissue (MALT) lymphoma is predominantly found in the stomach. Rarely, it is found in the proximal colon and even less so in the sigmoid colon. We present a rare case of primary sigmoid colon MALT lymphoma in a patient with concomitant Helicobacter pylori and hepatitis C infection. We also review current imaging, staging, and therapeutic modalities. To our knowledge, t...
Lymphocytic interstitial pneumonia (LIP) and mucosa-associated lymphoid tissue (MALT) lymphoma of lung are all uncommon disorders of respiratory system. MALT lymphoma of lung is a distinct and unique subtype of marginal zone B-cell non-Hodgkin's lymphoma (NHL) characterized by malignant cells arising from extranodal sites. They are characteristic of exuberant lymphoid infiltration in pathologic...
