 A71-year-old male patient was followed up by a neighboring physician as having submucosal tumor. The patient developed dysphagia and visited our clinic, where he was diagnosed as having a huge esophageal submucosal tumor with its base at the beginning of the esophagus. Endoscopic resection was performed under general anesthesia using a jumbo snare inserted from the anal side. As the pedicle part was relatively narrow, it was easy to excise, but it was difficult to extract it orally. Therefore, a part of it was recovered and the excision was terminated. Histopathological examination revealed atypical lipoblasts and the patient was diagnosed with differentiated liposarcoma. Immunostaining showed atypical lipoblasts and S-100protein positive. We encountered this extremely rare esophageal liposarcoma case and reported it here. The local recurrence rate was said to be high, so strict follow-up has been necessary thereafter.
