Adenoid cystic carcinoma with hyperostosis after stereotactic radiosurgery.
Adenoid cystic carcinoma (ACC) of the head and neck is a relatively rare tumor characterized by slow evolution, recurrences, and protracted clinical course. We performed stereotactic radiosurgery in order to palliate symptoms for intraorbital recurrence of ACC that had been treated with total resection of the left parotid gland, radical neck dissection, and conventionally fractionated radiotherapy. We experienced interesting hyperostosis in the area irradiated by the stereotactic radiosurgery.
