Inflammatory Myofibroblastic Tumor of the Nasal Cavity / 대한이비인후과학회지

ABSTRACT

Inflammatory myofibroblastic tumor is an uncommon tumor composed of myofibroblasts and various types of inflammatory infiltrates that rarely undergoes malignant transformation. It commonly involves the lung, liver, mesentery but rarely affects the head and neck region. Although inflammatory myofibroblastic tumor is generally considered a benign reactive inflammatory process, it may present clinically and radiologically as an invasive mass destructing the surrounding structures. Therefore, it should be considered as one of several differential diagnoses from malignant tumors. We present a case of inflammatory myofibroblastic tumor involving the nasal cavity, maxillary, ethmoid, and sphenoid sinus with a fatal outcome.
