Snare traction-assisted endoscopic submucosal dissection for removal of rare giant laryngeal liposarcoma

A 78-year-old man presented with a foreign body sensation in the throat for 1 year. Endoscopy revealed a large pedunculated tumor in the throat, extending deep into the mid-thoracic esophagus ([Fig. 1]). Computed tomography (CT) of the throat showed a column-like region with a density similar to fat located within the larynx and esophageal entrance to the mid-thoracic lumen, without significant contrast enhancement ([Fig. 2]).
