Successful endosocpic submucosal dissection for esophageal squamous cell carcinoma together with a lipoma.

Superficial carcinomas over submucosal tumors of the esophagus have seldom been detected. Esophageal lipomas are very rare and only a few cases have been reported. We describe the case of a 73-year-old man with superficial squamous cell carcinoma overlying a lipoma. We successfully performed en bloc resection by endoscopic submucosal dissection (ESD) using the IT-knife. Histological examination showed curative resections. In such cases, ESD may be a promising tool to perform less invasive treatment.
