Abstract：
:Liposarcomas represent between 15 and 18% of all sarcomas with the most common site being the extremities and retroperitoneum. Liposarcomas of the head and neck are rare, with an estimated incidence representing 3 to 5.6% of all liposarcomas. Liposarcomas most commonly present in the soft tissues of the neck. Primary liposarcoma of the hypopharynx (piriform sinus) is extremely rare. The symptoms presented are principally dysphagia, dyspnea, dysphonia, airway obstruction and sensation of a foreign body. Treatment of choice is surgery, and the literature describes the performance of lateral pharyngotomy, simple excision and even total laryngectomy. We present the case of a 23-year-old patient who was diagnosed 7 years prior with liposarcoma of the piriform sinus. The patient underwent surgery using a cervical approach. The tumor recurred 4 years postoperatively and the patient was again surgically intervened using the same approach. He presented to our Institute with 3 months evolution of dysphonia. Nasofibrolaryngoscopy and imaging studies were performed. Surgical treatment was decided upon with CO2 laser using suspension microlaryngoscopy, obtaining excellent results. Some of the advantages of this approach are low morbidity because of the avoidance of performing a tracheostomy, rapid return to oral feeding without necessity of a feeding tube, and reduction in hospitalization days. Disadvantage includes difficulty in evaluating margins.
