Huge liposarcoma of esophagus resected by endoscopic submucosal dissection: case report with video

Inku Yo et al. Clin Endosc. 2013 May.

Abstract

Liposarcoma is one of the most common soft tissue sarcomas occurring in adults, but it rarely occurs in the gastrointestinal tract and more uncommonly in the esophagus. To the best of our knowledge, there are only 19 reported cases of esophageal liposarcoma in the literature published in English language up to the year 2008, and they were all treated by surgical methods. Here, we report a case of primary liposarcoma of the esophagus which was treated with endoscopic submucosal dissection (ESD). ESD was well tolerated in this patient, suggesting that it may be a therapeutic option for primary esophageal sarcomas.

Contrast-enhanced computed tomography scan (A, transverse view; B, coronal view) images demonstrate a tumor (arrowheads) protruding into the esophageal lumen. The large tumor is almost completely obstructing the esophagus.

(A) Esophagogastroduodenoscopy image shows a huge mass with stalk. (B) Endoscopic ultrasonography image shows a submucosal mass located in the posterior wall of upper to mid esophagus. The diameters of the mass were 12.7 and 37.1 mm, respectively.
