Abstract
- Primary hepatic sarcoma is a rare tumor, with fewer than 60 previously reported cases. It is thought to arise from hepatic connective tissue or vascular channels. The tumor is located usually in the intrahepatic area. Pedunculated or bulging lesion is also reported. We report a case of primary leiomyosarcoma of the liver occuring in a 62-year-old Korean woman. A pedunculated, 21 16 cm sized mass is located in the left lateral segment of the liver. Microscopically, the tumor is hypercellular and composed of elongated, partly pleomorphic spindle cells with blunt-ended nuclei, which are focally reactive for muscle specific actin. Mitotic figures are 5/10 high power fields (HPFs). No other primary site is recognized on clinical study.
