A Case of Retropharyngeal Liposarcoma Causing Obstructive Sleep Apnea / 대한이비인후과학회지

ABSTRACT

Although liposarcomas are second most frequently encountered sarcomas that occur in soft tissue, liposarcomas of the head and neck are very uncommon. Liposarcomas of the retropharyngeal space are rare and do not cause symptoms until they reach a large size to cause mass effect. Depending on the location of the pharyngeal tumor, patients may present with foreign body sensation on throat, swallowing difficulty, respiratory difficulty, a painless neck mass, or obstructive sleep apnea. Recently we have experienced a case of retropharyngeal liposarcoma causing obstructive sleep apnea, so we report our clinical experiences with a brief review of literature.
