title: A case of lymphoepithelial cyst of pancreas with unique "cheerios-like" appearance in EUS.
abstract: Lymphoepithelial cyst (LEC) of the pancreas is a rare benign lesion, which is difficult to diagnose preoperatively. We describe a case of a 60-year-old male, incidentally diagnosed as having LEC of the pancreas, which was managed by laparoscopic distal pancreatectomy. Most of the reported cases of LEC were asymptomatic and diagnosed incidentally. A high index of suspicion under EUS may help in making a diagnosis and avoiding unnecessary surgery in asymptomatic patients. In particular, the unique "cheerios-like" appearance of the lesion in EUS, which was also found in this case, might be helpful in the differential diagnosis of pancreatic cystic lesions.
