Abstract
- Lymphoepithelial cyst of the pancreas is a rare benign cystic tumor which is histologically characterized by cyst containing keratin, lined by mature squamous epithelium surrounded by lymphoid tissue, often with prominent follicles. Cystic lesions of the pancreas are more often detected because sensitive abdominal imaging tests are used for multiple indications, but preoperative differential diagnosis is difficult despite the advancements of imaging technologies. We herein report a case of lymphoepithelial cyst incidentally found on routine abdominal ultrasonography which showed characteristic findings on endoscopic ultrasonography preoperatively and discuss the radiologic features of lymphoepithelial cyst.
