A patient with a secondary (radiation induced) fibrosarcoma in the mandible is presented. A 59-year-old man visited our hospital with a complaint of swelling and pain in the left mandible. He had previously undergone radiation therapy for a tonsillar tumor 7 years ago. Under the clinical diagnosis of a malignant tumor, surgical excision was performed. Final tissue analysis of the surgical specimen revealed it be fibrosarcoma. Twenty-five months later, he died from recurrence in the temporal region and neck.
In addition, a retrospective analysis presented on 80 cases of fibrosarcoma in Japan diagnosed between 1969 and 1991.
