Primary Hepatic Leiomyosarcoma: A case report

ABSTRACT

The liver is a distinctly unusual locus for a primary leiomyosarcoma. In October 1994, a 64-year-old female patient was admitted with palpable mass at the right upper abdomen for 2 months. Ultrasonography and Computed Tomography revealed a big cystic nature tumor at the right lobe of the liver. A right lobectomy was undertaken. On gross examination of the specimen, the tumor size was measured a 7.5 cm 16.0 cm 4.5 cm. On a cut section, cystic degeneration was showed and the color of the solid component was grayish. Microscopic examination growth pattern of the tumor to be expansive with no capsule. Finally the leiomyosarcoma of the liver was diagnosed with 5 to 6 mitosis per 10 high power fields. In September 1995, follow-up Computed Tomography revealed a recurred mass on segment 4 of the liver. A tumonectomy was performed. Twenty-one months after the second operation, recurrence was noted on the remaining liver and intraabdomen. Debulking surgery of the intraabdominal mass with intraperitoneal chemotherapy was undertaken. We report this case of primary hepatic leiomyosarcoma with a review of the literatures.
