A 45-year-old woman presented with right hypochondrial pain. Magnetic resonance imaging showed a choledochal cyst. Excision of choledochal cyst with Roux-en-Y hepaticojejunostomy was performed. A segment of dilated common bile duct and an attached nodule was received. Sections from the choledochal cyst showed a cyst wall composed of dense fibrous tissue lined by partially ulcerated columnar epithelium. Sections from the nodule showed interlacing whorls of smooth muscle bundles with entrapped glands. The glands were lined by cuboidal to columnar cells without nuclear atypia. This was recognized as an adenomyoma. To the best of our knowledge, this is the first reported case in which an adenomyoma was found associated with a type 1 choledochal cyst. A review of the existing literature and discussion of theories of genesis and the diagnostic pitfalls are presented.<\/jats:p>","DOI":"10.4103\/0377-4929.81640","type":"journal-article","created":{"date-parts":[[2011,5,28]],"date-time":"2011-05-28T10:08:01Z","timestamp":1306577281000},"page":"365-367","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":4,"title":["Adenomyoma of common bile duct arising in a type I choledochal cyst"],"prefix":"10.4103","volume":"54","author":[{"given":"Deepak Kumar","family":"Singh","sequence":"first","affiliation":[{"name":"Department of Pathology, UCMS and GTB Hospital, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Archana","family":"Rastogi","sequence":"additional","affiliation":[{"name":"Department of Pathology, Govind Ballabh Pant Hospital, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Puja","family":"Sakhuja","sequence":"additional","affiliation":[{"name":"Department of Pathology, Govind Ballabh Pant Hospital, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ranjana","family":"Gondal","sequence":"additional","affiliation":[{"name":"Department of Pathology, Govind Ballabh Pant Hospital, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-20250922","first-page":"216","article-title":"Partial biliary obstruction due to adenomyoma of the terminal common bile duct","volume":"11","author":"Gilbert","year":"1986","journal-title":"Clin Med"},{"key":"R2-20250922","first-page":"1627","article-title":"Adenomyoma of the common bile duct","volume":"46","author":"Tsukamoto","year":"1999","journal-title":"Hepatogastroenterology"},{"key":"R3-20250922","first-page":"432","article-title":"Adenomyoma of common bile duct.","volume":"83","author":"Cook","year":"1998","journal-title":"Am J Gastroenterol"},{"key":"R4-20250922","first-page":"388","article-title":"Adenomyoma of the papilla of Vater","volume":"111","author":"Ulich","year":"1987","journal-title":"Arch Pathol Lab Med"},{"key":"R5-20250922","doi-asserted-by":"crossref","first-page":"547","DOI":"10.1007\/BF02347577","article-title":"Adenomyoma of the common hepatic duct","volume":"30","author":"Imai","year":"1995","journal-title":"J Gastroenterol"},{"key":"R6-20250922","first-page":"132","article-title":"Adenomyoma of the common bile duct: Report of a case","volume":"47","author":"Ojima","year":"2000","journal-title":"Hepatogastroenterology"},{"key":"R7-20250922","doi-asserted-by":"crossref","first-page":"45","DOI":"10.1055\/s-2007-1021574","article-title":"The presence of a positive pressure gradient from pancreatic duct to choledochal cyst demonstrated by duodenoscopic microtransducer manometry: Clue to pancreaticobiliary reflux","volume":"14","author":"Tanaka","year":"1982","journal-title":"Endoscopy"}],"container-title":["Indian Journal of Pathology and Microbiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/00004270-201154020-00025","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T13:50:31Z","timestamp":1787838631000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/00004270-201154020-00025"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,4]]},"references-count":7,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2011]]}},"URL":"https:\/\/doi.org\/10.4103\/0377-4929.81640","relation":{},"ISSN":["0377-4929","0974-5130"],"issn-type":[{"value":"0377-4929","type":"print"},{"value":"0974-5130","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,4]]}}}
