title: Successful resection of giant esophageal liposarcoma by endoscopic submucosal dissection combined with surgical retrieval: a case report and literature review.
abstract: Liposarcoma of the esophagus is very rare. We experienced a huge (27.5 × 11.6 cm) liposarcoma of the esophagus. A 73-year-old man presented with severe dyspnea requiring emergency tracheal intubation. Computed tomography and esophagogastroduodenoscopy showed a large submucosal tumor arising from the esophageal entrance and extending intraluminally to the lower esophagus. We successfully performed endoscopic submucosal dissection (ESD) and esophagotomy to remove the tumor, which preserved swallowing and phonation. The final diagnosis by histopathologic and immunohistologic examination was well-differentiated liposarcoma of the esophagus. Treatment by the combination of ESD and esophagotomy can be performed even for a very large tumor. This method preserves deglutition with a lower risk of recurrent laryngeal nerve paralysis than that with esophagectomy.
