Core Tip
Core tip: Gastric duplication cyst is a very rare gastrointestinal malformation and most of the cases are diagnosed within the first year of life following clinical investigations of abdominal symptoms including pain, vomiting, and palpable mass. Gastrointestinal hemorrhage is a rare clinical manifestation. Here, we report a 52-year-old man who presented with a one-month history of progressive iron deficiency anemia without overt gastrointestinal bleeding. Esophagogastroduodenoscopy revealed general gastrointestinal bleeding and a 2.0 cm subepithelial tumor originating from the third layer of gastric wall. After complete removal by endoscopic mucosal resection, histopathological findings indicated a diagnosis of gastric duplication cyst with erosion.
