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 gastric melanoma is an extremely rare clinical entity. The clinical manifestation is not specific and usually similar with other common malignancies at this site, such as gastric cancer and lymphoma. And there are no specific radiological features either. Preoperative diagnosis via biopsy is usually difficult, since melanoma pigment could be absent in the biopsy tissue. Here, we report ...

Basal serum gastrin in 40 patients with benign gastric ulcer was 103 +/- 10.7 pg/ml, a level significantly higher than corresponding estimations in normal subjects and patients with duodenal ulcer. Following stimulation by a protein meal, a mean rise of 124 pg/ml was achieved at 75 minutes and prior atropinization induced a rise of 208 pg/ml at 90 minutes. Insulin hypoglycaemia produced a rise ...

The authors present the clinical case of a 14-year old girl with weight loss, anorexia, epigastric abdominal pain and postprandial vomiting with 5 months duration. There was a background of trichophagia for 2 years without evidence of alopecia or psychiatric history. The physical examination revealed an epigastric mass motionless, stony, with poorly defined limits, painful on palpation and abou...

CONTEXT Submucosal lesions of the gastrointestinal tract represent a diagnostic challenge for the physician. Endoscopic ultrasonography may provide useful information before deciding on therapeutic strategy. CASE REPORT We report on a case of a young female presenting with a large gastric submucosal mass, 32 mm in size. Endoscopic ultrasonography identified a non-homogeneous lesion, with thre...

The synchronous occurrence of primary renal cell carcinoma with gastric cancer is very rare. We report a case of 41 year old male who presented on 05/07/2011 to M S Ramaiah hospital, Bangalore with history of fever, pain abdomen and malena. Ultrasound abdomen and pelvis showed large heterogenous mass arising from the upper pole of left kidney. Computed tomography of the abdomen showed left rena...

Gastrointestinal (GI) duplication cysts are a rare congenital disease. They may involve any level of the alimentary tract, but they most commonly involve the ileum, esophagus, and jejunum. Gastric duplication cysts represent approximately 4-8% of GI duplication cysts, the majority of which present in early childhood. We present a rare case of adult gastric duplication cyst in a 25-year-old fema...

Degradation components of basement membrane could be crucial for tumor invasion. A key role in this process has been assigned to cysteine proteases, i.e. cathepsins and matrix metalloproteinases. The purpose of this study was to investigate the relationship of the expression of MMP-9 and cathepsin B with tumor aggressiveness expressed by lymph node metastases and survival rates in gastric carci...

Glycosylation in cancer is a highly dynamic process that has a significant impact on tumor biology. Further, the attachment of aberrant glycan forms is already considered a hallmark of the disease state. Mass spectrometry has become a prominent approach to analyzing glycoconjugates. Specifically, matrix-assisted laser desorption/ionisation -mass spectrometric imaging (MALDI-MSI) is a powerful t...

Context Gastric pancreatic heterotopia is a relatively common incidental finding; however, malignancy arising in this tissue is an extremely rare occurrence, with nonspecific clinical, radiographic, and intraoperative features. We herein report the case of adenocarcinoma arising in ectopic pancreatic tissue of the gastric antrum and review the literature to summarize all recent cases of maligna...
