A Rare Case of Well-Differentiated Parapharyngeal Liposarcoma

초록

Parapharyngeal liposarcoma is a rare malignant tumor, the pathogenesis of which is uncertain. Parapharyngeal liposarcoma often causes nonspecific clinical features, including dysphagia, globus sensation, and/or respiratory disturbances. The parapharyngeal space is a rare location for head and neck liposarcoma, and these lesions may therefore be confused with a variety of other tumors that can originate in this area. Here, we report a case of liposarcoma originating from the prestyloid parapharyngeal space and discuss the possible differential diagnosis on radiographic findings.
