BACKGROUND
Biliary papillomatosis is a condition characterized by multiple papillary tumors of variable distribution and extent within the biliary tract. Papillary carcinoma can develop in these lesions. It is a rare biliary pathological entity and its clinical features and outcome are not well known.
METHODS
We experienced a case of biliary papillomatosis in a 51-year-old North African man who presented with obstructive jaundice. Laboratory tests showed elevated bilirubin, alkaline phosphatase and gamma-glutamyl transpeptidase levels. Imaging (ultrasound and magnetic resonance imaging) was suggestive of Klatskin tumor associated to common bile duct stones. After endoscopic retrograde cholangiopancreatography, a balloon sweep retrieved friable tissue from his bile ducts. Histology demonstrated papillary adenomatous proliferation showing high-grade dysplasia and he was referred for surgical management.
CONCLUSIONS
Although biliary papillomatosis is rare, it is a premalignant condition that should be well known and considered in all diagnoses of obstructive jaundice. We report a new case of biliary papillomatosis and highlight the contribution of endoscopic retrograde cholangiopancreatography in the diagnosis of this condition.
