title: Ampullary xanthogranulomatous inflammation mimicking periampullary cancer: report of a case.
abstract: BACKGROUND
  Xanthogranulomatous inflammation commonly affects the gallbladder. To date, there have been no reports of xanthogranulomatous inflammation of the ampulla.
  
  
  METHODS
  A 48-year-old female presented to us with fever, jaundice and a palpable gallbladder. Evaluation revealed features of periampullary malignancy. The patient underwent a Whipple's pancreaticoduodenectomy. Histopathology revealed a xanthogranulomatous inflammation affecting the ampulla and the gallbladder.
  
  
  CONCLUSIONS
  Xanthogranulomatous inflammation should be added to the differential diagnosis of patients presenting with a suspected periampullary lesion accompanied by a thick-walled gallbladder.
