A Case of a Pancreatic Lymphoepithelial Cyst with Sebaceous Glands Treated by Laparoscopic Distal Pancreatectomy

Abstract

The patient was a 57-year-old male who presented with epigastric and back pain. Imaging revealed a 50-mm hypovascular cystic mass in the pancreatic tail containing fat components. Differential diagnoses included lymphoepithelial cyst (LEC), dermoid cyst, and liposarcoma. Over time, the mass increased in size, and laparoscopic distal pancreatectomy was performed. Histopathology showed a benign squamous epithelium with dense lymphocytic infiltration and adipocyte nests without hair follicles, confirming a final diagnosis of pancreatic LEC with sebaceous glands.
