title: Primary pancreatic lymphoma: diagnostic and therapeutic dilemma.
abstract: OBJECTIVE
  Non-Hodgkin lymphoma predominantly involving the pancreas is a rare tumor and accounts for less than 0.7% of all pancreatic malignancies and 1% of extranodal lymphomas. Diagnosis of primary pancreatic lymphoma can be difficult because it may mimic carcinoma. The principal aims of this review were to highlight the difficulties encountered in making a diagnosis and to identify the role of surgery.
  
  
  METHODS
  A PubMed search was conducted using the following terms: primary pancreatic lymphoma and non-Hodgkin lymphoma of the pancreas. Additional references were sourced from key articles.
  
  
  RESULTS
  A total of 89 reported cases of pancreatic lymphoma between 1951 and 2005 were reviewed. An accurate preoperative diagnosis of primary pancreatic lymphoma is not always possible. A complete response rate of 100% and a long-term survival rate of 94% have been reported with surgery and adjuvant chemotherapy when compared with a 5-year survival rate of less than 50% and an overall 3-year disease-free survival rate of 44% with current chemotherapy, radiotherapy, or combined methods.
  
  
  CONCLUSIONS
  Pancreaticoduodenectomy may have a therapeutic role in association with chemotherapy.
