Among the 27 patients, 12 males and 15 females, age ranged from 8 to 77 years, with a median 43 years old. Treatment included 1 with radiotherapy, 22 with surgery, 3 with surgery and postoperative radiotherapy, one with concurrent chemoradiotherapy followed by surgery. Of the 27 cases, 5 located in the neck, 6 in the nasal and paranasal sinus, 4 in the temporal bone, 3 in the throat, 2 in the parotid gland, 2 in the lower pharynx, 1 in the mandible, 1 in the maxilla, 1 in the masseter muscle, 1 in the amygdala and 1 in the pharynx nasalis.</p><p><b>RESULTS</b>Following-up time was 4-85 months, with a median of 26 months. Six cases lost follow-up, 1 case with malignant transformation and died, 16 cases survived with no recurrence, 4 cases relapsed, of whom 2 were alive with tumors and 2 died.</p><p><b>CONCLUSIONS</b>IMT in the head and neck has a tendency to be malignancy, with certain recurrence rate and mortality. Radical excision is still the first choice of treatment for IMT in head and neck.</p>
