A case of liposarcoma in a giant pedunculated lipoma of the esophagus in a 49-year-old Korean woman who presented intermittent swallowing difficulty for 3 years is reported. Endoscopy and esophagography revealed that a giant smooth longitudinal tumor mass almost entirely occupied the esophageal lumen. A total esohagectomy was done. The tumor was 20 cm in length and 7 cm in average diameter with an obvious stalk measuring 3 cm in length and 1 cm in diameter. Microscopic examination disclosed a lipoma with focal ulceration and liposarcomatous change infiltrating into interstitial fibrous tissue at its distal end.
