Acute epigastric pain is commonly encountered among young adults undergoing military training. Gastric malignancy usually affects older individuals and may occasionally masquerade as peptic disease. We report a case of primary gastric lymphoma (PGL) in a young soldier, presenting as an acute upper gastrointestinal tract bleeding. The case is presented along with a review of the relevant literat...

The majority of malignant tumors of the stomach are carcinomas. It has been reported in the literature that lymphomas consist of 1%-5% of all malignant tumors of the stomach (1). The simultaneous coexistence of adenocarcinoma and malignant lymphoma of the stomach is extremely rare (1-5). Gastric carcinoma and primary gastric lymphoma have shown to be related to Helicobacter pylori infection (3)...

We present a case of a 56-year-old man with 3 synchronous gastric tumors. The patient presented with melena, and 3 gastric abnormalities were detected on gastroduodenoscopic examination, including a small ulcerative lesion in the gastric antrum, a submucosal mass in the gastric body, and severe erosion in the fundus. Histological examination of biopsy samples yielded respective diagnoses of gas...

Lymphocytic gastritis and primary gastric lymphoma are rare conditions with unknown aetiology. It has recently been suggested that Helicobacter pylori has a role in the pathogenesis of both of them. The occurrence of lymphocytic gastritis and H pylori was studied in a series of patients with primary gastric lymphoma. The cases of primary gastric lymphomas (n = 35) diagnosed in years 1970-1993 w...

BACKGROUND In contrast to gastric extranodal marginal zone mucosa associated lymphoid tissue (MALT) lymphomas, there is little consensus on the value and clinical consequences of extensive staging at diagnosis and during follow-up in non-gastric MALT lymphomas. DESIGN AND METHODS Complete clinical information at presentation and during follow-up was collected for 72 patients with non-gastric ...

BACKGROUND Helicobacter pylori (H. pylori) infection has been postulated to be a pathogenetic factor in gastric lymphoma. However, the etiological factors for gastric lymphoma could vary in different populations. MATERIALS AND METHODS We looked for histological evidence of H. pylori infection in 53 gastrectomy specimens from Hong Kong Chinese patients with primary gastric B-lymphoma. We also ...

Primary gastric T cell lymphoma is rare and mostly of large cell type. In this paper, we present a case of gastric T cell lymphoma morphologically similar to the gastric marginal zone B cell lymphoma of mucosa-associated lymphoid tissue (MALT). Morphologically, the cells are small with abundant clear cytoplasm. Lymphoepithelial lesions are readily identified with diffuse destruction of gastric ...

Mantle cell lymphoma represents 2.5-7% all of non Hodgkin's lymphomas. Stomach is the most common site of extranodal lymphoma. However, that is not the case with mantle cell lymphoma, which is extremely rare. We present a case of 71-year-old woman admitted to the Internal Clinic of the University Clinical Hospital Center Rijeka, because of stomach discomfort and melena. Endoscopy and computed t...

Among 121 cases of primary gastric malignant lymphoma from 1962 to 1994 at the National Cancer Center Hospital, Tokyo, we found four cases (three males and one female) of adenocarcinoma coexisting in the stomach. The incidence of gastric malignant lymphoma together with gastric adenocarcinoma was 3.3%, suggesting that patients with lymphoma may have an increased incidence of gastric adenocarcin...
