RESUMEN
A 68-year-old female patient was referred to our hospital with acute cholangitis. Computed tomography revealed common bile duct dilatation, gallbladder fundal tumor, and gallbladder wall thickening attached to the tumor. Cholangiography revealed pancreaticobiliary maljunction with biliary dilation. The patient was diagnosed with pancreaticobiliary maljunction with biliary dilation and gallbladder cancer and underwent liver S4b+5 and bile duct resection and reconstruction. Pathological results revealed that the gallbladder fundal tumor included sarcoma, and the gallbladder wall thickening had adenocarcinoma;thus, the patient was diagnosed with gallbladder carcinosarcoma.

We describe a case of a 47-year-old male patient with initially unresectable intrahepatic cholangiocarcinoma of the right liver lobe with tumor thrombi extending from the right bile duct to the common and left bile ducts. Conventional chemotherapy with gemcitabine and cisplatin for 19 months resulted in progressive disease. Subsequently, a comprehensive genome profile revealed fibroblast growth factor receptor 2 rearrangement, and hence, pemigatinib administration was initiated. After 6 months of pemigatinib therapy, significant shrinking of the tumor and disappearance of the tumor thrombi in the common and left bile duct were observed. Subsequently, the patient underwent conversion surgery, resulting in successful radical resection of the tumor. The patient has been disease-free for 7 months.
