ABSTRACT
A case of an extremely rare cystic lesion of the pancreas is presented. The multilocular cyst was found adjacent to the upper border of the pancreatic body, and the cyst contained bean curd lees-like substances. Histologically, the cyst wall consisted of mature keratinizing squamous epithelium and surrounding lymphoid tissue stroma, and the cyst was filled with keratinized materials. A histopathologic diagnosis of typical lymphoepithelial cyst of the pancreas, proposed by Truong et al (Am J Surg Pathol 11899-903, 1987), was made. Its histogenesis is still unknown; however, we hypothesize that it might arise from a benign epithelial inclusion of a peripancreatic lymph node, followed by squamous metaplasia of the epithelial inclusion. We recently found a retropyloric lymph node with a squamous epithelial inclusion, which might support this hypothesis regarding the histogenesis of the cyst.
