Lymphoepithelial cyst of the pancreas

Abstract

Pancreatic lymphoepithelial cysts are rare and benign lesions, the pathogenesis of which remains unknown. Morphologically resembling cystic neoplasms, they pose challenges in differential diagnosis. They are truly benign cysts that typically occur in salivary glands and their occurrence in the pancreas is extremely rare, accounting for approximately 0.5 % of pancreatic cystic lesions. More prevalent in males, they often manifest asymptomatically or with nonspecific abdominal discomfort.
