title: Intraductal and invasive adenocarcinoma of duct of Luschka, mimicking chronic cholecystitis and cholelithiasis.
abstract: BACKGROUND
  Intraductal and invasive adenocarcinoma of duct of Luschka is rare. To the best of our knowledge, this is the second case report of intraductal and invasive carcinoma arising from ducts of Luschka.
  
  
  METHODS
  Patient presented to hospital with signs and symptoms of chronic cholecystitis and cholelithiasis. Ultrasound examination revealed thickening of gallbladder wall with abnormal septation around liver bed. Patient underwent laparoscopic cholecystectomy and resection of the adjacent liver bed. Histologic examination confirmed an intraductal and invasive adenocarcinoma arising from Luschka ducts.
  
  
  CONCLUSIONS
  Adenocarcinoma of ducts of Luschka should be considered among differential diagnoses for the patients with typical clinical presentations of chronic cholecystitis and cholelithiasis.
