Radiation-induced osteochondromas.
Radiation-induced osteochondromas, either single or multiple, occur more commonly than is generally recognized. The incidence following irradiation for childhood malignancy is approximately 12%. Any open epiphysis is vulnerable. Age at irradiation, time of appearance following therapy, dose and type of radiation, and clinical course in 14 cases are discussed. Due to growth of the lesion and/or pain, 3 tumors were excised. None revealed malignant degeneration.
