Liposarcoma, the second most commom soft-tissue sarcoma in adults, arises predominantly in the extremities or retroperitoneum, less frequently in the head and neck region, and rarely in the neck. We report a case of myxoid-type liposarcoma of the neck.<br> A 50-year-old man with a few years’ history of an enlarging painless swelling in the frontal-medial aspect of the neck, measuring 48×40mm in size at the present examination, was found on computed tomography (CT) to have a mass extending between the thyrohyoid muscle and the platysma. We extirpated the tumor with the overlying skin. Histological examination confirmed the diagnosis of myxoid-type liposarcoma. The tumor was completely covered with velamen, and the surgical margin was negative for tumor. No adjuvant therapy has been given, and the patient remains recurrence-free 27 months after surgery.<br>
