Esophageal liposarcoma is extremely rare, and only 13 cases have been reported so far. We herein report a case of this disease which was successfully treated and also include a literature review. A 68-year-old man visited our hospital due to progressive dysphasia. An esophagography revealed an exophytic mass in the cervical esophagus. On endoscopy, the tumor showed subepithehal growth with a positive cushion sign. MRI revealed the tumor to be composed of two components separated by a septum. The tumor was completely resected through an esophagotomy. The glossy tumor was found to be a pedunculated submucosal tumor, which was histologically found to be a myxoid liposarcoma. The patient had an uneventful postoperative course with a normal esophageal function. Because of the pedunculated configuration and the low-grade malignant nature of these tumors, a tumor resection with a negative surgical margin through an esophagotomy may be the most appropriate treatment in these cases.
