Follicular cholangitis, a rare benign condition, presents with symptoms and imaging similar to malignancies like cholangiocarcinoma, often complicating diagnosis, particularly when tumor markers are elevated and imaging suggests metastasis. Case presentation: A 57-year-old woman with hypertension and diabetes was admitted with jaundice. Elevated bilirubin and liver enzymes alongside high carbohydrate antigen 19-9 (CA19-9) levels but normal carcinoembryonic antigen (CEA) were noted. Imaging showed thickening from the hilar duct to the proximal common bile duct, accompanied by suspected lymph node metastases. Comprehensive ERCP-guided biopsies found no malignancy. Surgical resection led to a diagnosis of follicular cholangitis. Conclusions: Follicular cholangitis\u2019 long-term prognosis is elusive due to its rarity, and preoperative diagnosis is challenging. Increased awareness may improve diagnostic and treatment approaches, as this case adds to the disease\u2019s understanding.<\/jats:p>","DOI":"10.3390\/medicina60091513","type":"journal-article","created":{"date-parts":[[2024,9,18]],"date-time":"2024-09-18T00:51:43Z","timestamp":1726620703000},"page":"1513","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Diagnostic Challenges in Follicular Cholangitis Mimicking Hilar Cholangiocarcinoma: A Case Report and Review of the Literature"],"prefix":"10.3390","volume":"60","author":[{"given":"Jungnam","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Inha University Hospital, Inha University School of Medicine, Incheon 22332, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6178-8338","authenticated-orcid":false,"given":"Seok","family":"Jeong","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Inha University Hospital, Inha University School of Medicine, Incheon 22332, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Don Haeng","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Inha University Hospital, Inha University School of Medicine, Incheon 22332, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suk Jin","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Pathology, Inha University Hospital, Inha University School of Medicine, Incheon 22332, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Woo Young","family":"Shin","sequence":"additional","affiliation":[{"name":"Department of Surgery, Inha University Hospital, Inha University School of Medicine, Incheon 22332, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"304","DOI":"10.1016\/j.jss.2013.06.028","article-title":"Sensitivity of endoscopic retrograde cholangiopancreatography standard cytology: 10-y review of the literature","volume":"184","author":"Burnett","year":"2013","journal-title":"J.
