[A case of huge intrahepatic cholangiocarcinosarcoma]

A 77-year-old woman was referred to our hospital because of right-back pain. Dynamic computed tomography (CT) studies showed a huge tumor in the right lobe of the liver. After admission, transcatheter arterial embolization (TAE) was immediately performed because of the risk of rupture. The tumor, however, was hypovascular and we judged that the procedure had no effect on preventing rupture. Therefore, based on a diagnosis of cystadenocarcinoma or cholangiocarcinoma, we conducted right trisegmentectomy and caudate lobectomy in July 2010. The definitive pathological diagnosis was intrahepatic cholangiocarcinosarcoma. The postoperative course was uneventful, and the patient was discharged on postoperative day (POD) 17. Afterwards, despite chemotherapy treatment, a local recurrence on the right diaphragm was detected 2 months postoperatively, and she died 4 months postoperatively. Intrahepatic cholangiocarcinosarcoma is very rare. We report this case with a review of some relevant literature.
