Abstract
- Inflammatory myofibroblastic tumor (IMT), which is composed of spindle shaped myofibroblasts accompanied by an inflammatory infiltrate, is an uncommon neoplasm. Herein we present a rare case of an IMT of the parotid gland. The patient was a 56-year-old woman with parotid mass, which developed a tingling sensation around the mouth angle when the mass was palpated. Ultrasound and CT scan showed a parotid mass with an ill-defined margin. Preoperative gun biopsy showed spindle shaped cell proliferation without cytological atypia. Surgery revealed that the mass was adhesive to buccal branch of facial nerve without encapsulation. The adhesive part of the facial nerve was excised with mass due to the possibility of malignancy. The final pathological report confirming IMT became available following the surgery. We stress that confirmation of IMT should be included in the differential diagnosis of parotid mass which shows spindle shaped cells in histology.
