Lymphoepithelial tumors of the pancreas are rare cystic tumors characterized by the presence of a keratinizing squamous epithelium and a dense lymphoid infiltrate on histologic examination. This case report describes the first lymphoepithelial tumor to be resected from the pancreatic head by pancreaticoduodenectomy. This case is also the first in which the cyst was found to be secondarily infected. The radiologic and clinicopathologic features of these unusual tumors are discussed.
