BACKGROUND. Lymphoepithelial cysts (LECs) of the pancreas are extremely rare, benign, nonneoplastic cysts that can mimic pseudocysts or cystic neoplasms clinically and radiographically. The cytologic features of LECs have been described only in a handful of case reports and may overlap with both ben

We describe the cytologic features seen in fine-needle aspiration (FNA) specimens from two cases of preoperatively diagnosed lymphoepithelial cyst (LEC) of the pancreas. Pancreatic LEC is a rare, true cyst of uncertain histogenesis that may clinically and radiologically mimic a pseudocyst or cystic
Fine needle aspiration cytology has been increasingly used in recent years to diagnose pancreatic lesions. During a 6 year period, we performed 33 aspiration cytologies of the pancreas. Twenty-one were performed during exploratory laparotomy, seven under the guidance of computed tomography and five
Leiomyosarcoma of the pancreas is very rare. [1][2][3] Metastatic cases from the stomach, duodenum, vena cava, and splenic vein resembling a primary pancreatic lesion have been described. 4 We report a case of metastatic leiomyosarcoma involving the pancreas that was diagnosed by fine-needle aspirat
