title: Case of spontaneous regression of metastatic lesions of leiomyosarcoma of the esophagus.
abstract: A rare case of spontaneous regression of esophageal leiomyosarcoma is reported. A 63-year-old woman underwent esophagectomy and reconstruction at our hospital after diagnosis of leiomyosarcoma. Nineteen months after esophagectomy, a coin lesion was detected in the right lung and right thoracotomy revealed pleural dissemination. The lesion in the right lung was resected and was confirmed histologically as recurrence of leiomyosarcoma. During further surgery, metastatic lesions were found in the spleen and pleura. However, all metastatic lesions were found to decrease without any anti-cancer therapy.
