Biliær papillomatose er en sjælden årsag til intermitterende obstruktiv ikterus

Over a five-year period a 67 year-old male had been experiencing recurring bouts of biliary obstruction with occasional superimposed cholangitis. Renewed endoscopic retrograde cholangiopancreatography revealed amorphous filling defects and excessive mucinous discharge from the papilla of Vater. Subsequent choledochoscopy demonstrated exophytic papillomatous lesions in the common and left hepatic bile duct. An extended left hemihepatectomy and resection of the common hepatic bile duct was performed. Histological examination revealed biliary papillomatosis - a rare lesion believed to be premalignant.
