Myxofibrosarcoma is a soft tissue neoplasm, usually arising in elderly patients especially in the limbs, but very rarely in the head and neck region. We report a rare case of myxofibrosarcoma in the oropharynx. A 48-year-old man visited our department complaining of pharyngeal dysesthesia. A tumor was detected inside the left palatine tonsil. The cervical lymph node was not palpable. MRI showed a 40×25×20 mm mass. Resection of the tumor was performed. The tumor was histopathologically and immunohistochemically diagnosed as low-grade myxofibrosarcoma. Myxofibrosarcoma is very rare in the oropharynx. Though the tumor is a low-grade malignancy, complete resection of the tumor must be performed.
Key words :myxofibrosarcoma, oropharynx, low-grade type
