A lymphoepithelial cyst of the pancreas: A case report / 대한내과학회지

ABSTRACT

A lymphoepithelial cyst of the pancreas is a rare, benign disease. A 58-year-old man with no abdominal symptoms was found to have a cystic mass in the pancreas. Computed tomography showed a multi-septated cystic mass in the tail of the pancreas. We performed a distal pancreatectomy with a splenectomy. Histological examination revealed that the cyst wall was lined with squamous epithelium and surrounded by lymphoid tissue. Keratinous material was present in the cyst. A lymphoepithelial cyst of the pancreas should be considered in the differential diagnosis of all cystic pancreatic lesions. Fine-needle aspiration biopsy may be a useful strategy, but local surgical resection of the cyst, for most patients, should be considered to exclude malignancy.
