It is often difficult to correctly diagnose patients who present with dilation of the bile duct. Cholangiocarcinoma, primary sclerosing cholangitis (PSC) and immunoglobulin (Ig)G4-related sclerosing cholangitis must be considered as potential diagnoses for these cases. The current study presents a 73-year-old female patient who presented with a high fever and abdominal pain. Contrast-enhanced computed tomography and magnetic resonance cholangiopancreatography revealed stenosis and dilation of the intrahepatic bile duct without solid components. It was suspected that the patient had intrahepatic cholangiocarcinoma. A left liver lobectomy, cholecystectomy and distal gastrectomy combined with a D2 lymph node dissection were performed. A pathological examination of the liver revealed increased fibrosis in the stroma, irregular bile duct dilation and clusters of inflamed lymph cells. No carcinoma or IgG4-positive plasma cells were observed and the typical findings of PSC were not detected. Based on these clinical and pathological results, the diagnosis was idiopathic sclerosing cholangitis, which is particularly rare. It is often difficult to preoperatively differentiate between cholangiocarcinoma and benign bile duct stenosis.

Surgery is the only known curative treatment option for cholangiocarcinoma. Ex situ liver surgery and autotransplantation are promising approaches in cases that cannot be treated by conventional methods and particularly in the presence of centrally localized liver tumors as well as tumors that invade the main vascular structures. A 53-year-old female patient presented with abdominal pain and nausea. Abdominal tomography showed a tumoral mass lesion that filled the left lobe of the liver and invaded the left hepatic vein and the inferior vena cava. Cholangiocarcinoma diagnosis was reached based on biopsy findings, and the patient was scheduled for surgery as positron emission tomography did not indicate any other disease focus. The patient underwent ex situ liver resection and autotransplantation. She was discharged on the 7th postoperative day. A 68-year-old male presented with abdominal pain, weakness, and weight loss. Laboratory analysis indicated elevated carbohydrate antigen 19-9: 400 U/ml and alpha-fetoprotein (AFP): 2000 U/ml, and there was no other pathology. Abdominal tomography showed a mass that filled the center of the liver and invaded the left hepatic vein and the inferior vena cava. Pathological findings of the biopsy sample were reported as combined hepatocellular-cholangiocellular carcinoma. The patient's AFP levels continued to increase despite transcatheter arterial chemoembolization and radiofrequency ablation therapy. Surgery was decided as indocyanine green clearance test, and the result was 8.5%. He underwent ex situ liver resection and autotransplantation. Unfortunately, he died on the 4th postoperative day due to respiratory failure. Ex vivo liver resection and partial liver autotransplantation should be considered for the surgical treatment of locally advanced cholangiocarcinomas that invaded the main vascular structures.

A 78-year-old woman with a chief complaint of mammary tumor was referred to our hospital and was diagnosed with mucosa-associated lymphoid tissue (MALT) lymphoma using needle biopsies. She presented with MALT lymphoma lesions in the stomach, duodenum, and intraperitoneal lymph nodes. Abdominal ultrasonography revealed thickened internal layer of the bile duct. Cholangiocarcinoma, immunoglobulin G4-related sclerosing cholangitis, and MALT lymphoma were suspected. She did not report any abdominal pain, and did not have jaundice. Endoscopic retrograde cholangiopancreatography and intraductal ultrasonography indicated diffuse, irregular wall thickening with the formation of nodule lesions in the extrahepatic bile duct. Transpapillary cytology indicated CD20-positive atypical lymphocytes. MALT lymphoma of the bile duct was diagnosed. CVP with rituximab therapy was performed. After treatment, computed tomography, gastrointestinal endoscopy, endoscopic retrograde cholangiopancreatography, intraductal ultrasonography, and transpapillary cytology revealed that the tumor and the biliary wall thickening had disappeared. It is difficult to diagnose MALT lymphoma of the bile duct. We report a case in which intraductal ultrasound and transpapillary cytology were useful for establishing a diagnosis and evaluating the therapy for MALT lymphoma of the bile duct.
