[Primary hepatic sarcomatoid carcinoma, an unusual case].

Abstract

Primary hepatic sarcomatoid carcinoma is a very aggressive tumor, representing 0.4-0.7% of all primary hepatic neoplasms. The disease is associated with liver disease due to hepatotropic viruses and is more prevalent in Asians. Histology shows sarcomatous and carcinoma components. It does not have pathognomonic clinical or imaging characteristics and its diagnosis is based on the pathological and immunohistochemistry findings. Surgery could prolong survival in localized stages. We report the case of a 72-year-old Korean patient with a history of chronic liver disease due to B virus, who was diagnosed with primary hepatic sarcomatoid carcinoma with bone and lymph node metastases.
