Abstract

Liposarcoma in larynx and hypopharyx is an extremely rare and dedifferentiated liposarcoma that has never been reported in Korean literature. The 48-year-old male patient was referred to ENT because of acute airway obstruction during gastrofiberscopic biopsy. The neck and chest CT scan showed pharyngeal mass extending esophagus and lateral neck. In operation, we found that pharyngeal and lateral neck mass were connected through pharyngeal wall. The mass was removed en bloc via open neck and lateral pharyngotomy approach. The postoperative pathologic examination revealed dedifferenciated liposarcoma. We report a very rare condition with a literature review.
