A case of lymphoepithelial cyst in the pancreas was reported. A 64-year-old man without any specific compalints was found to have a cystic lesion in the anterior portion of the pancreas, as revealed by ultrasonography of the abdomen at an annual medical examination in 1988.

Cysts of this type are rare, and their histogenesis is also not well understood.
