Gastric duplication cyst. Endoscopic presentation as an ulcerated antral mass

Abstract

A case of a 53-year-old man who presented with epigastric pain and weight loss is described. Endoscopy showed a smooth antral mass with what appeared to be a central overlying ulcer. Computerized tomography and upper gastrointestinal series confirmed the presence of a gastric mass. Laparotomy and local resection showed a gastric duplication comprised of two cysts, one with communication to the stomach lumen. Gastric duplication is a rare entity, especially in the adult. Though generally benign, local ulceration or fistula formation can cause symptoms and may suggest a more malignant process that warrants investigation.
