Abstract |
Lymphoepithelial cysts of the pancreas, which are lined by squamous epithelium and surrounded by mature lymphoid tissue, represent
a rare clinicopathologic entity of cystic lesions of the pancreas and true pancreatic cysts. Here, we report a case of lymphoepithelial
cyst of the pancreas and a review of the related Korean literature. A 58-year-old man presented to our hospital with an
asymptomatic pancreatic mass and no remarkable medical history except hypertension. Physical examination and laboratory analyses
showed no abnormalities. Ultrasonography (US) revealed a cystic lesion with heterogeneous internal echo within the body of
the pancreas, and computed tomography (CT) revealed a low-density lesion (2.3×1.5 cm) with well-defined margins and lobulating
contour. To further characterize the mass, a biopsy was collected via endoscopic ultrasonography (EUS)-guided fine-needle
aspiration. Histological examination revealed fibrous tissue and epithelial cells, but was insufficient for a definitive diagnosis.
Laparotomy revealed that the mass was composed of keratinizing squamous epithelial cells surrounded by lymphoid tissue, thereby
confirming the diagnosis of lymphoepithelial cyst of the pancreas. (Korean J Med 76:S54-S58, 2009) |
