Pancreatic lymphoepithelial cyst: a case report

Pancreatic lymphoepithelialcyst （PLEC） is a rare benign pancreatic cyst， which has been rarely reported in clinical practice. The incidence of PLEC is low and specific imaging and clinical manifestations are lacking. It is difficult to make differential diagnosis between PLEC and pancreatic cancer， which is likely to be misdiagnosed. In this article， a 63-year-old male patient who was suspected with PLEC due to a pancreatic mass detected during physical examination was reported. Upon admission， endoscopic ultrasound-guided fine-needle aspiration （EUS-FNA） promoted the diagnosis of benign lesions. Subsequently， surgical resection was performed and he was pathologically diagnosed with PLEC.This case prompts that EUS-FNA can be used as a preferential treatment for pancreatic cystic lesions
