A 72-year-old male visited our hospital complaining of foreign body sensation in the throat. On fiberscopic examination, we found a round smooth mass with a pedicle arising from the posterior wall of the mesopharynx. The tumor was resected along its capsule using an oral approach, with a preoperative diagnosis of benign tumor. The pathological diagnosis was a liposarcoma of the myxoid type, and radiation therapy was performed postoperatively.
Although liposarcoma is the second most common soft-tissue sarcoma in adults, the incidence of liposarcoma of the head and neck is low. There have been 41 reported cases of head and neck liposarcoma in Japan, among which only two cases arising from the pharynx have been detected.
