Pansinusitis secondary to inflammatory myofibroblastic tumor

Inflammatory myofibroblastic tumors are aetiologically enigmatic and biologically unpredictable lesions. The lungs are the organs of apparent predilection. These tumors have also been documented in a number of extrapulmonary sites including head and neck. Paranasal location is rare. We report a case of a maxillary location in a 10 years and 10 months old girl initiated as an acute pansinusitis.
