Abstract
Biliary intraepithelial neoplasia (BilIN), a precursor lesion of bile duct adenocarcinomas, rarely occurs in the extrahepatic bile duct, and therefore uniform treatment guidelines are lacking. The present study reports a case of BilIN in the common bile duct (CBD) in a 77‑year‑old man, who presented with upper abdominal malaise without jaundice. Imaging modalities revealed a CBD luminal tumor and dilated intrahepatic and extrahepatic bile ducts. To the best of our knowledge, local excision of the lesion was performed for the first time for this type of tumor in the present study. Pathological examination gave a definite diagnosis of high‑grade BilIN in the CBD. No evidence of recurrence was observed during a 3-year follow-up period. This case report suggests that local excision is able to successfully treat BilIN in the CBD.
