Giant esophageal liposarcoma diagnosed by endoscopic ultrasound

Abstract

We report a case of giant well-differentiated esophageal liposarcoma in a Chinese patient. Liposarcoma is a common soft tissue malignant tumor that usually arises in the lower extremities, trunk, and the retroperitoneum, but it is very rare that liposarcoma locates in the gastrointestinal tract, especially in the esophagus. Endoscopic ultrasound could be an efficient tool for preliminary examination. Moreover, the patient underwent combined thoraco-laparoscopic surgery, after reviewing the published articles, this surgery was first applied in the excision of esophageal liposarcoma due to the detailed preoperative information from the ultrasound technique.
