Foregut Duplication Cyst as a Rare Cause of Hematemesis: A Case Report

JPMS-VOL3-ISSUE3-PAGES123-126-IMAGE1Duplications of the gastrointestinal tract are rare congenital malformations that usually present in the first two years of life with symptoms of poor weight gain and palpable abdominal mass. We report here a case of a 9-year-old boy who was evaluated for massive upper gastrointestinal bleeding. Upper endoscopy revealed a submucosal large mass in fundus of the stomach with a 3-centimeter diameter ulcer. Our provisional diagnosis was gastrointestinal stromal tumor (GIST) which was later revised to gastric duplication cyst. Gastric duplication cyst is misdiagnosed as leiomyoma or GIST endoscopically and it should be considered in the differential diagnosis of gastrointestinal mass in young children.
