A CASE REPORT OF LEIOMYOSARCOMA OF THE RECTUM WITH RIGHT HEPATIC LOBECTOMY FOR LIVER METASTASIS

Abstract

Leiomyosarcoma of the alimentary tract is a relatively uncommon disease, but recently, some cases have been reported in Japan. Because of the severe liver metastasis and poor prognosis, surgical treatment of liver metastasis of leiomyosarcoma has been rare.In a patient with leiomyosarcoma of the rectum, liver metastasis was diagnosed by abdominal CT scan, because of the presence of an intrahepatic low-density area. A right partial lobectomy was performed and liver metastasis of the leiomyosarcoma of the rectum was diagnosed histopathologically.Liver metastasis of leiomyosarcoma is difficult to diagnosis because its clinical findings often differ. It is important to diagnose liver metastasis early as possible, by means of ultrasonography and computed tomography. Further more, hepatectomy for metastasis of leiomyosarcoma is useful for treating this disease, so in general should be performed.
