title: Gastric Duplication Cyst With Elevated Amylase: An Unusual Presentation Mimicking Pancreatic Cystic Neoplasm.
abstract: Enteric duplication cysts (EDCs) are benign congenital anomalies that are found incidentally in adults. Gastric duplication cysts (GDCs) are the least common subtype of EDC, but when located near the pancreas, may resemble other neoplastic conditions. We report a case of GDC adjacent to the pancreas with high cystic fluid amylase and carcinoembryonic antigen (CEA) and 3 different epithelia (respiratory, gastric, and intestinal), all diagnosed via endoscopic ultrasound with fine-needle aspiration.
