A Case of Gastric Duplication Cyst at Fundus Presenting as a Large Subepithelial Tumor

ABSTRACT

Gastric duplication cyst is a congenital disease and an uncommon finding in adult patients. Presenting symptoms are often asymptomatic during adulthood. Most cases are discovered incidentally by radiological examination or gastric endoscopy. Preoperative diagnosis of gastric duplication is difficult because definitive diagnosis requires a well-developed coat of smooth muscle with an epithelial lining that represents some portion of the alimentary tract in the lesion. In majority of reported cases, the diagnosis is established by surgical exploration and the treatment is primarily managed by complete excision. We report a case of a gastric duplication cyst in a 40-year-old man.
