title: Giant pedunclated lipoma of the esophagus: A case report.
abstract: BACKGROUND
  Although Esophageal lipoma is extremely rare and pathologically benign, surgical excision of the lipoma is recommended when symptomatic or uncertain biological behavior. In general, some of the esophageal lipoma has a stalk. The pedunclated non-invasive tumor can be removed by stalk ligation, which is either endoscopic or surgical approache. Therefore, the preoperative evaluation is essential. We herein present a case of a huge esophageal lipoma.
  
  
  METHODS
  A 82-year-old man, with a wet cough and dyspnea for 6 months, who had the huge mass that almost completely occupied the esophageal lumen, was referred to our institution for the treatment.We diagnosed the mass as non-invasive tumor that has a stalk at the close to the esophageal orifice, by the CT image using air injection into esophageal lumen. We performed excision of the pedunclated huge mobile mass by esophagotomy via right thoracic approach with use of endoloop. Pathological examination showed a lipoma.
  
  
  CONCLUSIONS
  In conclusion, an adequate preoperative evaluation to identify the correct origin of the stalk is mandatory for a successful treatment. In order to do the adequate preoperative evaluation and successful surgery, our diagnostic method of CT image can be effective.
