Abstract:
An epidermoid cyst arising from intrapancreatic accessory spleen (ECIPAS) is a rare disease. Most patients with an ECIPAS are detected incidentally and could be misdiagnosed as a pancreatic cystic neoplasm such as mucinous cystic neoplasm (MCN) or intraductal p ancreatic mucinous neoplasm (IPMN). We described an ECIPAS with high cystic fluid carcinoembryonic antigen (CEA), which was misdiagnosed as a MCN of pancreas. Fifty one-year-old female was presented with a 2 cm sized non-enhancing pancreas cystic mass on the outside CT scan. Endoscpic ultrasonography (EUS) guided aspiration was performed. It showed a 2.3 x 1.9 cm unilocular cyst nearby 1.6 x 1.1 cm homogenous hypoechoic mass in pancreas tail, and cystic fluid CEA was 1564.18 ng/mL. On the basis of EUS results with elevated fluid CEA level, the presumptive diagnosis is likely to MCN of pancreas, and she underwent a laparoscopic distal pancreatectomy. The final pathology was the epidermal cyst in the intrapancreatic accessory spleen.
