Abstract
Liposarcoma is one of the most common soft tissue sarcomas in adults with a relative incidence amongst other sarcomas ranging from 9.8% to 16%. It usually locates in the limbs and retroperitoneum. Primary liposarcomas of the larynx and hypopharynx are rare, comprising less than 20% of all head and neck liposarcomas. According to World Health Organization, these tumors are divided into four histologic types, and well-differentiated liposarcoma is the most common one. It is a tumor of low-grade malignancy that may recur locally, but does not metastasize. We present a case of laryngopharyngeal well- differentiated liposarcoma in an old patient with two previous removals. We also discuss recently published cases with this unusual location of liposarcoma.
