Abstract
- A primary hepatic sarcoma is a rare tumor, that most frequently arises from hepatic connective tissue or vascular channels, and is usually located in the intrahepatic area. Pedunculated, or bulging, lesions have also been reported. We encountered a pedunculated primary hepatic leiomyosarcoma occurring in a 61-year-old woman. A giant exophytic hepatic mass measuring 15x10cm in size, was located in the left lateral segment of the liver, which was compressing the stomach. A left lateral segmentectomy was performed. Microscopically, the tumor was composed of spindle cells reactive to muscle specific actin. The mitotic figures were 5/10 high power fields indicating the tumor was malignant. No other primary sites were recognized from clinical studies.
