  OBJECTIVE
  Rare disease.
  
  
  BACKGROUND
  Primary Aorto-Enteric Fistula (PAEF) is a unique and rare life threatening communication between the Aorta and Gastrointestinal Tract with an unusually high mortality rate and delayed diagnosis. Aortic abdominal aneurysms are implicated in a vast majority of cases while cancer as an etiology of PAEF is extremely rare.
  
  
  METHODS
  We present the first case report of a PAEF secondary to Large B-Cell Lymphoma, followed by a review of literature in regards to malignant aorto-enteric fistulae.
  
  
  CONCLUSIONS
  We conclude that physicians should maintain a high index of suspicion for PAEF in any patient with unexplained anemia and history of aortic abdominal aneurysm complicated by cancer.
