Liposarcoma of the hypopharynx is exceedingly rare. Only 20 cases were reported in literature. The mean age was 59 years, and males are largely predominant. The well differentiated Liposarcoma was the most common histological diagnosis found. The treatment was based on surgery, by external or endoscopic approach. Surgery was associated with radiotherapy in high grade tumors, and those aggressive locally or in case of incomplete surgical excision. The survival rate without a local recurrence was about 83% in literature. We report 2 others cases of hypopharyngeal well-differentiated liposarcoma, with literature review.
