Liposarcoma is the second most common soft tissue sarcoma in the adult population, accounting for approximately 15% of all sarcomas. It is most commonly found in the extremities or the retroperitoneum.1 Head and neck liposarcoma accounts for between 3% and 5.6% of all liposarcomas.2 The majority of head and neck liposarcomas arise in the soft tissues of the neck. Sarcomas represent only 1% to 2% of all laryngeal tumors, up to half of which are fibrosarcomas.3 Primary liposarcoma of the larynx or hypopharynx is exceedingly rare, with fewer than 50 cases identified in the literature.
