Apropos of a case of pancreatic lymphoepithelial cyst: importance of the preoperative diagnosis by ecoendoscopy.

Abstract

The case was a 75-year-old female with dyspeptic symptoms of a 2 month duration. There was a polycystic lesion at the level of the uncinate pancreatic process of 44 x 42 x 34 mm on abdominal ultrasound and MRI, which caused a slight dilation of the main pancreatic duct. EUS was performed that identified a multicystic formation of 25x36 mm in the pancreatic body and FNA was performed of the lesion. The cytological analysis identified squamous epithelial cells with lymphoid tissue, which was compatible with a lymphoepithelial cyst, with no evidence of cell atypia or other signs of malignancy. Radiological control and monitoring of the lesion was performed and it has remained stable for 2 years.
