Abstract

Inflammatory myofibroblastic tumor (inflammatory pseudotumor) is a term used to describe the space occupying the neoplastic lesion rather than the inflammatory lesion. Its occurrence in the maxillary sinus is rare. The etiology and pathophysiology of the maxillary inflammatory myofibroblastic tumor is unknown. The diagnosis must be based on histological evidence to exclude other disease. We report a case of a 72-year-old patient with maxillary and nasal cavity inflammatory myofibroblastic tumor that simulated an invasive neoplasm in its clinical presentation, Radiologic findings showed near total coagulation necrosis histopathologically.
