Two cases with lymphoepithelial cysts of the pancreas

Abstract

A lymphoepithelial cyst of the pancreas is a rare benign condition which occurs mainly in middle-aged males. If a diagnosis of lymphoepitehlial cyst can be confirmed before surgery, further treatment would not be needed. However, ruling out malignant disease is extremely difficult, because it often shows features of both multilobular cysts and serum CA19-9 elevation, which can lead to a false diagnosis of mucin-producing neoplasm, resulting in excision in many cases. Two similar cases, both males in their sixties, were treated surgically and are reported and discussed herein.
