The occurrence of superficial carcinoma over a benign tumor of the esophagus is considered to be rare. Only a few reports have been reported and all of them were treated surgically. We now report one case of superficial carcinoma overlying an esophageal lipoma that was successfully resected endoscopically. The patient was a 61-year-old man who had no symptoms. A submucosal tumor was found at the thoracic esophagus by upper gastrointestinal endoscopy. The top of the tumor was slightly depressed with mild redness and its surface was irregular. This depressed lesion was not stained by iodine. Histological examination of endoscopic biopsy revealed squamous cell carcinoma. To completely remove this tumor in a single fragment, we used an insulation-tipped electrosurgical knife. An en bloc resection of the tumor was completed without complications.
