A RESECTED CASE OF HEPATIC METASTASIS OF GASTRIC LEIOMYOBLASTOMA 10 YEARS AFTER AN OPERATION FOR THE PRIMARYTUMOR

A 53-year-old woman was admitted to the hospital because of abdominal distention in 1995. There was a history of undergoing a wedge gastric resection for a leiomoyblastoma of the stomach at another hospital in 1985. On admission to the hospital, a tumor was palpable in the right upper abdominal quadrant, as a size of childhead, and elastic hard consistency. Abdominal CT showed a low density mass in the left lobe of the liver. The wall of the tumor was enhanced in the contrast CT scan. The angiography of the celiac artery showed that the main artery was stretched by the mass and a part of the tumor was feed by the left hepatic artery. Resection of the tumor with a caudate hepatic lobectomy was performed. The final diagnosis of the tumor was liver metastasis of the leiomyoblastoma. Postoperative course was uneventful and the patient was discharged from the hospital on 17th day after the operation. Only 15 cases of leiomyoblastoma of the stomahc with liver metastasis have been reported previously in Japan. And six cases had liver reccurence after resection of the primary tumor. We report a rare case which could be resected the liver metastases 10 years after the operation for the gastric leiomyoblastoma.
