Inflammatory myofibroblastic tumour of the maxillary sinus and the oral cavity.

BACKGROUND: Inflammatory myofibroblastic tumours (IMT) are benign lesions that mimic malignant neoplastic processes due to their infiltrating and destructive nature. They can be found anywhere in the body, although they are most commonly located in the lung. IMTs of the head and neck region are rare entities. CASE REPORT: We report a case of a maxillary IMT with an enlarged intraoral component which was adequately treated with surgical excision without long-lasting additional corticosteroid treatment. DISCUSSION: Inflammatory myofibroblastic tumours can be easily misdiagnosed as malignant neoplastic processes due to their destructive nature. Proper diagnosis is essential to avoid mutilating and disfiguring surgical procedures.
