Duplication cysts of the mediastinum are not common. Morrison (1958) includes six in a series of 332 mediastinal cysts and tumours; in his Table 1 (which includes his own series) 15 gastric and enterogenous cysts were found in a total of 1,055 published cases of mediastinal cysts and tumours, an incidence of 1 5 %. Although cases have been described (Mixter and Clifford, 1929; Gross, Neuhauser ...

She underwent an abdominal ultrasound that revealed a right lower quadrant cystic mass. A Technetium-99 scan revealed increased activity in the right lower quadrant consistent with a Meckel's diverticulum. Following a nondiagnostic laparoscopic evaluation, a laparotomy was perfo...

Duplication cyst of the stomach is a rare congenital malformation, typically diagnosed in the first year of life. In most adult cases the cyst remains asymptomatic, but patients may present with abdominal symptoms including epigastric discomfort or pain. We present a case of a 65-year-old male with an asymptomatic gastric tumor diagnosed incidentally during initial workup of his esophageal aden...

Infection with cagA-positive Helicobacter pylori is critically associated with the development of gastric cancer. The cagA-encoded CagA is delivered into gastric epithelial cells via type IV secretion, where it interacts with and thereby deregulates the pro-oncogenic phosphatase SHP2. East Asian CagA and Western CagA are two major CagA species produced by H. pylori circulating in East Asian cou...
