title: EUS-guided Trucut biopsies may enable the diagnosis of lymphoepithelial cysts of the pancreas. Report of two cases.
abstract: BACKGROUND
  Lymphoepithelial cysts are rare benign lesions of the pancreas. Endoscopic ultrasound guided fine needle aspiration (FNA) has reportedly been helpful in reaching a diagnosis of lymphoepithelial cyst. In cases where it may be difficult to obtain a diagnosis using FNA a histological sample may be obtained using EUS guided Trucut biopsy.
  
  
  METHODS
  We describe two cases of lymphoepithelial cysts where a diagnosis of lymphoepithelial cyst was made using EUS guided Trucut biopsy.
  
  
  CONCLUSIONS
  In some case, lymphoepithelial cysts may present a diagnostic dilemma. EUS with FNA and Trucut biopsy may enable the clinician to make a definitive diagnosis.
