Aggressive fibromatosis of the parotid gland

Summary

We describe the case of a 34-year-old woman who presented with a painful parotid mass. She was found to have an extra-abdominal fibromatosis of her right parotid gland. Medical management with antibiotics and immunosuppression therapy was unsuccessful. Surgical resection was required for both a definitive diagnosis and management. Preoperative findings on computed tomography, magnetic resonance imaging, and both fine-needle aspiration biopsy and surgical biopsy were nonspecific, as is typical in EAF cases.
