Abstract: | Inflammatory myofibroblastic tumor (IMT), popularly known as inflammatory pseudotumor, is a slow growing quasi-neoplastic lesion with a distinct histologic appearance and benign clinical course. A case of a neck IMT with infiltration into the trachea causing asthmalike symptoms in a 12-year-old girl is described. Both tracheal and neck IMT have been described, but no other case has displayed this infiltration. A review of the pertinent literature and the etiology, diagnosis, treatment, and outcomes of this tumor are discussed. It is important to consider IMT in a differential diagnosis because it can be easily misdiagnosed as a malignancy. A surgeon must not perform radical surgery, radiation, or chemotherapy until a final pathologic diagnosis is made because of the nature of this lesion. |
