We report 3 cases of possible radiation-induced schwannomas observed in our Department. Their salient clinical and pathogenetic features are analyzed and the role of radiation therapy in the oncogenesis of these lesions is discussed. Several cases of radiation-induced tumors, including some of the nervous system, have been reported, but schwannomas have only occasionally been reported in connection with ionizing radiation. The possible adjuvant role of antineoplastic drugs is also discussed, and the literature on this topic is reviewed.
