Core Tip
Core tip: Intrahepatic sarcomatoid cholangiocarcinoma is rare condition. Patients usually present with an advanced stage of the disease, and they have a poor prognosis. Diagnosis based on histopathologic examination is important because serologic and radiologic examinations cannot help in distinguishing such condition from intrahepatic bile duct adenocarcinoma or other intrahepatic masses. Thus, patients must be diagnosed as early as possible and should receive aggressive treatment, including surgical resection.
