Inflammatory myofibroblastic tumor of the maxillary sinus: A case report.

Inflammatory myofibroblastic tumors (IMTs) are one of the most complex and rare neoplasms that have been discovered, with varying behavior in different cases. They mostly arise in the thoracic and abdominal cavity, the lungs, retroperitoneum, and extremities. They can also be detected in the head and neck area. IMTs have no age or gender preference which makes them tougher to anticipate. Head and neck IMTs are benign neoplasms with locally aggressive behavior and a low risk of metastatic spread. They have an unknown etiology, and they resemble malignant lesions radiologically. In this case report, we will review the case of a 40-year-old woman with an unusual IMT in the maxillary sinus that presented as a challenge in diagnosis and management.
