Abstract
This report presents the case of a 48-year-old male with an inflammatory myofibroblastic tumor (IMT) of the maxillary sinus. IMT is a distinct borderline lesion composed of myofibroblastic cells with a variable admixture of inflammatory cells. This disease is most often reported in the lungs, and it is uncommon in the head-and-neck region. It is generally difficult to diagnose IMT, because IMTs in the head and neck region have no specific features on computerized tomography and magnetic resonance imaging and fine-needle aspiration cytology is unreliable. A recurrence rate of approximately 25% has been reported for extra-pulmonary IMTs. Careful long-term observation with CT or MRI is important.
