title: Pathology Report: Presacral Noncommunicating Enteric Duplication Cyst.
abstract: BACKGROUND
  Gastrointestinal (GI) tract duplication cysts or enteric duplication cysts are rare congenital malformations sometimes found on the mesenteric aspect of segments of the alimentary tract. Enteric duplication cysts are lined by normal GI epithelium and may be classified as foregut, mid-gut, and hindgut cysts. Except in very rare cases of retroperitoneal enteric duplication cysts, these cysts communicate with the GI tract and share a common blood supply. Concurrent congenital malformations are not uncommon and malignant transformation within enteric duplication cysts has also been reported.
  
  
  METHODS
  We describe a case of a noncommunicating enteric duplication cyst in a 52-year-old woman.
  
  
  RESULTS
  The patient presented with a presacral cystic mass requiring frequent drainage procedures that was primarily believed to be of neural origin. Upon resection, the lesion contained heterotopic tissue, including ciliated bronchial epithelium, squamous and transitional epithelia, and pancreatic and gastric tissue. Focal, low-grade intestinal adenoma was present, but malignancy was not detected in this case.
  
  
  CONCLUSIONS
  To our knowledge, this is the sixth reported case of a noncommunicating enteric duplication cyst in the English medical literature.
