Abstract
Follicular cholangitis (FC) is a rare non-neoplastic biliary tract disease first reported in 2003. A 74-year-old woman underwent extended left hepatectomy with a diagnosis of intrahepatic cholangiocarcinoma. Histopathological examination of the surgical specimen demonstrated no malignant findings, and lymphocytic infiltration with lymphoid follicles was observed within the bile duct wall. Along with immunohistochemical findings, the patient was diagnosed with FC. More than 3 years after surgery, the patient exhibited elevated hepatobiliary enzymes and total bilirubin. Endoscopic retrograde cholangiography revealed stricture and dilation from the extrahepatic bile duct to the right intrahepatic bile duct. Histopathological findings uncovered lymphocytic infiltration without malignant results. It was concluded that bile duct stricture due to FC had newly developed in her remnant liver. Subsequently, the patient developed hypoalbuminemia, and abdominal computed tomography revealed atrophy of the remnant liver and ascites accumulation. Esophagogastroduodenoscopy exposed the development of esophageal varices, which were not observed preoperatively. The patient was diagnosed with decompensated liver cirrhosis accompanied by portal hypertension. This case strongly suggests that long-term follow-up after surgery may be required for patients with FC for screening of potential new bile duct stricture and progression to liver cirrhosis due to cholestasis.

Abstract
BACKGROUND Follicular cholangitis (FC) is a benign bile duct disease that was first reported 2003. Pathologically, it is characterized by lymphoplasmacytic infiltration with multiple lymphoid follicle formations under the mucosal layer of the biliary tract. However, as this disease is extremely rare, little is known about its etiology and pathogenesis. CASE PRESENTATION A 77-year-old woman was diagnosed with middle bile duct stenosis and potential increases in alkaline phosphatase (ALP) and γ-glutamyl transpeptidase levels (γ-GTP). Carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9) and IgG4 levels were all within the normal limits. Contrast-enhanced computed tomography (CE-CT) and magnetic resonance imaging (MRI) revealed bile duct dilation from intrahepatic to upper common bile duct and an irregular mass lesion in distal bile duct. Additionally, multiple overlapping leaf-like folds were detected. 18F-fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG-PET/CT) did not demonstrate fluorodeoxyglucose uptake. Subtotal stomach-preserving pancreaticoduodenectomy with regional lymph node dissection was performed because common bile duct cancer could not be ruled out. The resected specimen showed diffuse homogeneous middle bile duct wall thickening. Microscopically, the lesion exhibited thick fibrosis with several invaded lymphoplasmacytic cells, and lymphoid follicle formations were detected under the mucosal layer. Immunohistochemical staining (IHC) revealed positive for CD3, CD4, CD20 and CD79a, and these findings led to a final diagnosis of FC. The patient has not experienced recurrence to date (42 months postoperatively). CONCLUSIONS Currently, accurate preoperative diagnosis of FC is difficult. More cases must be accumulated to generate additional knowledge on its precise diagnosis and proper treatment.

Abstract
Biliary epithelial cells preferentially respond to various insults under chronic pathological conditions leading to reactively atypical changes, hyperplasia, or the development of biliary neoplasms (such as biliary intraepithelial neoplasia, intraductal papillary neoplasm of the bile duct, and cholangiocarcinoma). Moreover, benign biliary strictures can be caused by a variety of disorders (such as IgG4-related sclerosing cholangitis, eosinophilic cholangitis, and follicular cholangitis) and often mimic malignancies, despite their benign nature. In addition, primary sclerosing cholangitis is a well-characterized precursor lesion of cholangiocarcinoma and many other chronic inflammatory disorders increase the risk of malignancies. Because of these factors and the changes in biliary epithelial cells, biliary strictures frequently pose a diagnostic challenge. Although the ability to differentiate neoplastic from non-neoplastic biliary strictures has markedly progressed with the advance in radiological modalities, brush cytology and bile duct biopsy examination remains effective. However, no single modality is adequate to diagnose benign biliary strictures because of the low sensitivity. Therefore, understanding the underlying causes by compiling the entire clinical, laboratory, and imaging data; considering the under-recognized causes; and collaborating between experts in various fields including cytopathologists with multiple approaches is necessary to achieve an accurate diagnosis.
