Successful endoscopic resection of intramural metastasis after esophagectomy for esophageal cancer: a case report.

Carcinoma of the esophagus is often accompanied by intramural metastasis (IM) at the time of diagnosis, and the prognosis of patients with such metastasis is very poor. Here we report the case of a 60-year-old man who presented with a submucosal tumor in the wall of the cervical esophagus at 2 years after esophagectomy for thoracic esophageal cancer. The tumor was resected endoscopically and was histologically shown to be an IM of esophageal cancer. He has shown no recurrence and no metastasis during 2 years of follow-up after endoscopic resection and radiation therapy.
