[Mandibular osteoradionecrosis caused by radiotherapy of lip cancer. Differential diagnosis with tumor recurrence].
The onset of the bone radionecrosis is a relatively unusual problem which should be considered in the differential diagnosis of recurrences of irradiated tumors showing a high degree of aggressiveness. The AA. present a case report of a re-operated lower lip carcinoma which underwent further radiation therapy. A bony mandibular lesion was then observed, which led to the diagnosis of tumoral invasion at the mandible, and a partial mandibulectomy was then performed. The histopathological examination revealed a bone necrosis, probably due to radiotherapy. The clinical features and therapeutic management of mandibular osteoradionecrosis are commented.
