title: Parotid carcinoma and posterior fossa schwannoma following irradiation. Report of a patient treated in infancy for benign ear disease.
abstract: A 23-year-old man had received irradiation for a benign ear problem at the age of 1 year. Twenty year later, a malignant left parotid carcinoma and a right jugular foramen schwannoma developed. Earlier reports in the literature suggest that radiation can induce tumors in the head and neck. The localization of both tumors and the histological features of the parotid tumor suggest that they were radiation-induced.
