An extremely rare case of intrahepatic sarcomatoid cholangiocarcinoma

One uncommon histological subtype of intrahepatic cholangiocarcinoma is sarcomatoid intrahepatic cholangiocarcinoma. Histopathological and immunohistochemical tests are used to diagnose sarcomatoid intrahepatic cholangiocarcinoma, which frequently has a worse prognosis than regular intrahepatic cholangiocarcinoma. The example of a 65-year-old female with sarcomatoid intrahepatic cholangiocarcinoma, who presented with sporadic right upper abdomen discomfort, is discussed in this paper. This case study and literature analysis aims to improve physicians’ comprehension of sarcomatoid intrahepatic cholangiocarcinoma and lower the frequency of missed clinical diagnoses.
