Three cases of inflammatory myofibroblastic tumor (IMT) in the head and neck region are reported. Case 1 was an 80-year-old male diagnosed with IMT of the parotid gland which was treated with partial parotidectomy and submandibular neck dissection. Case 2 was a 63-year-old male diagnosed with IMT on the middle ear which was treated with radical operation on the middle ear. Case 3 was a 71-year-old male diagnosed with IMT of the nasal cavity which was treated with septectomy. All patients are still alive without any recurrence. In these rare diseases of the head and neck area, pathological diagnosis was difficult to confirm from specimens. It is unresolved whether IMT is a true tumor or pseudotumor, so differentiation should be made the difference between IMT and other tumors or specific inflammation by immunological or genetic methods.
Key words : inflammatory myofibroblastic tumor, IMT, head and neck region, parotid gland, middle ear, nasal cavity
