[Successful resection of mediastinal and abdominal recurrent tumors of esophageal leiomyosarcoma 12 years after surgery].

A 57-year-old woman admitted to our hospital in October, 1988 because of the tumor of the abdominal wall and abnormal shadows of right chest wall and right upper mediastinum. Her esophagus had been resected and reconstructed by the stomach roll because of the esophageal leiomyosarcoma in May, 1976. Clinical examinations revealed that the abdominal mass and chest shadows were the recurrence of the leiomyosarcoma. The abdominal tumor was resected on 17th October, 1988. On 14th December, 1988 right thoracotomy was performed. Chest wall tumor (40 x 30 x 20 mm) and mediastinal tumor (45 x 40 x 35 mm) were resected completely. The mediastinal tumor was adhered to the remnant esophageal muscle layer. Microscopic section of the tumor showed spindle cell sarcoma with fine calcification, and it was diagnosed as the metastatic leiomyosarcoma.
