Abstract
|
|
|
Purpose: Malignant degeneration of fibrous dysplasia is an uncommon recognized complication of this disease. Especially, degeneration of fibrous dysplasia to malignant fibrous histiocytoma(MFH) in facial bone is rare and the publications had been limited. The purpose of this report is to share our experience.
Methods: A 46-year-old patient with facial fibrous dysplasia visited our clinic for recent facial tingling and swelling. Malignant degeneration of fibrous dysplasia was suspected.
Results: Total excision of the mass and adjacent facial bone was performed. Defect was immediately reconstructed with bone graft and bone cement. At a month follow up, metastasis was detected at ipsilateral parotid gland. Superficial parotidectomy and neck dissection was performed. The patient is currently taking chemotherapy.
Conclusion: Because of the uncommon presentation of this entity, clinical course of treatment was dependent on other histological types of malignant degeneration. We report this case to share our experience.
