N2 - Introduction: Liposarcomas are thought to be the most prevalent kind of soft tissue sarcoma in adults. A well-differentiated liposarcoma that has a higher incidence of a local recurrence following surgical excision is referred to as an atypical lipomatous tumor. The incidence are extremely rare in which <1 % of head and neck sarcoma cases. This is unusual liposarcoma localization warrants great interest in reporting such a case. Presentation of case: In this report we present a case of a 50-year-old male complained with difficulty swallowing solid food and continuous presence of lump in the throat. Fiber Optic Laryngoscopy (FOL) showed a tumor filled the hypopharynx and CT scan suggested a benign mass that was most likely a fibrolipoma. Discussion: Tumor was found infiltrating the lateral pharyngeal wall and protruding into the hypopharyngeal lumen. Because the tumor had spread to the right thyroid lobe, surgical excision via a transcervical approach was combined with a right thyroidectomy. There was a positive margin at the end of resection, thus a chemoradiation was added. Two years post-operative evaluation shows no sign of recurrence. Conclusion: The main treatment for hypopharyngeal liposarcoma is based on surgery, either through an endoscopic or transcervical approach which determined by the size of the tumor and surgical field. Adjuvant chemoradiation is given to help prevent the recurrence.
