We report the first case of esophageal liposarcoma in Japan. A 46-year-old female was admitted to our hospital with chief complaint of protruding tumor out of the mouth. She had two episodes of protruding tumor after nausea in last 6 months. Barium swallow showed a large polypoid lesion of approximately 16cm in length with a stalk. By endoscopic examination, it was the polyp originated from the anterior wall of the cervical esophagus. It was covered with intact squamous epithelia, which had slight redness and erosion in the apex. Under general anesthesia the tumor was cut off at the base through the oral cavity. Specimen was 11×4×3cm in size and had yellowish cut surface. Histologically, the tumor composed of mature adipocytes and many atypical lipoblasts with spider web shaped cytoplasm.
