Lymphoepithelial cyst of the pancreatic tail: a rare entity with surgical and histopathological insights.

Abstract

Lymphoepithelial cysts (LECs) of the pancreas are rare, benign lesions often discovered incidentally during imaging for unrelated conditions. Their radiological features frequently overlap with those of other more common pancreatic cystic lesions, presenting a diagnostic challenge. In this report from a general surgical department on the Australia, we detail the assessment and management of a 54-year-old male with an enlarging pancreatic tail lesion initially thought to be a mucinous cystic neoplasm. Laparoscopic distal pancreatectomy and splenectomy was performed, and subsequent histopathological evaluation confirmed a benign LEC. This report reviews the literature base, clinical presentation, radiological findings, surgical approach, and pathological diagnosis of this rare condition. We emphasize the importance of a tailored approach to management and the role of surgery in definitive treatment.
