Here, we report a case of xanthogranulomatous cholangitis mimicking cholangiocarcinoma.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation:<\/jats:title>\n                    <jats:p>A 72 year old male with history of recurrent cholangitis had preoperative workup highly suggestive of intrahepatic cholangiocarcinoma. He underwent right hepatectomy and portal lymphadenectomy, with pathology showing xanthogranulomatous cholangitis, with no evidence of malignancy. Interestingly, the patient did not have xanthogranulomatous cholecystitis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion:<\/jats:title>\n                    <jats:p>We reviewed the current literature on xanthogranulomatous cholangitis, and identified only 14 previously reported cases. In our case series, there were six female and eight male patients. Among the 14 patients, 11 presented to the hospital with jaundice. Twelve patients had preoperative workup concerning for malignancy. The diagnosis of xanthogranulomatous cholangitis was confirmed through pathology in 13 patients, and through endoscopic ultrasound biopsy in one patient. In our review, seven patients had associated xanthogranulomatous cholecystitis, three patients had an isolated case of xanthogranulomatous cholangitis, and four patients had unknown status. Our patient is the fourth case of isolated xanthogranulomatous cholangitis without xanthogranulomatous cholecystitis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Xanthogranulomatous cholangitis is a very rare phenomenon that can lead to benign strictures of the bile ducts, especially in the setting of recurrent cholangitis. It can mimic malignancies, such as cholangiocarcinoma, and should be considered in the differential diagnosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Highlights<\/jats:title>\n                  <\/jats:sec>","DOI":"10.1016\/j.ijscr.2022.106921","type":"journal-article","created":{"date-parts":[[2022,3,9]],"date-time":"2022-03-09T12:24:03Z","timestamp":1646828643000},"page":"106921","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":8,"title":["Xanthogranulomatous cholangitis mimicking cholangiocarcinoma"],"prefix":"10.1097","volume":"93","author":[{"given":"Jenny Q.","family":"Zhang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lance","family":"Truong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jason","family":"Pan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Evgeny","family":"Yakirevich","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah M.","family":"Hyder","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rachel E.","family":"Beard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-33-20260304","doi-asserted-by":"crossref","first-page":"771","DOI":"10.2169\/internalmedicine.54.2623","article-title":"Hepatic inflammatory pseudotumor associated with xanthogranulomatous cholangitis mimicking cholangiocarcinoma","volume":"54","author":"Bae","year":"2015","journal-title":"Intern.
