A 66-year-old woman presented to our outpatient clinic with abdominal discomfort in April, 2008. Ultrasound revealed a hypo-echoic 10cm mass in the right hepatic lobe but no indication of chronic liver disease, with similar results in her history, on physical exam, and imaging. Serum testing did not identify any systemic disease. The mass was suspected to be intrahepatic cholangiocarcinoma and right hepatic lobectomy was performed. Histologic examination of the specimen revealed numerous spindle cells, and immunostaining confirmed a definitive diagnosis of sarcomatoid carcinoma of the liver. On subsequent review of the case, an abdominal CT performed 2.5 years earlier for unrelated symptoms had shown a 1cm faint low density area in the same location as the mass. The doubling time of this tumor was about 95 days.
