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