Although benign, they present close similarity to malignant lesions and thus deserve important clinical consideration. We present a case of a 74\u2010year\u2010old Chinese man who presented acutely with fever and painless obstructive jaundice. CT imaging showed a large calculus within a dilated common bile duct (CBD) and, despite undergoing an endoscopic retrograde cholangiopancreatography (ERCP) with stone clearance, there was a persistent filling defect that was adherent to the wall of the proximal common bile duct. His CA 19\u20139 was also significantly raised. Intraductal ultrasonography (IDUS) showed a polypoid mass with papillary\u2010like projections, and ERCP forcep biopsies were unable to exclude a lesion with neoplastic potential. The patient subsequently underwent cholecystectomy with open CBD excision and Roux\u2010en\u2010Y hepaticojejunostomy, and histology showed features consistent with a biliary adenomyoma.<\/jats:p>","DOI":"10.1002\/jgh3.12739","type":"journal-article","created":{"date-parts":[[2022,4,6]],"date-time":"2022-04-06T07:23:56Z","timestamp":1649229836000},"page":"282-284","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Unusual cause of a polypoid lesion in the extrahepatic bile duct"],"prefix":"10.1002","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4639-5760","authenticated-orcid":false,"given":"Yu Bin","family":"Tan","sequence":"first","affiliation":[{"name":"Department of Gastroenterology Changi General Hospital  Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lai Mun","family":"Wang","sequence":"additional","affiliation":[{"name":"Pathology Section, Department of Laboratory Medicine Changi General Hospital  Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew B E","family":"Kwek","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology Changi General Hospital  Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,4,6]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-84241-2"},{"key":"e_1_2_5_3_1","first-page":"6","article-title":"Tumors of the bile ducts","volume":"54","author":"Marshall JM","year":"1932","journal-title":"Surg.
