Postirradiation parosteal osteosarcoma. A case report.
A 16-year-old Japanese boy received a high dose of radiation for treatment of eosinophilic granuloma in the femur at the age of two years. He presented with a parosteal osteosarcoma 14 years later. Although a number of cases of postirradiation osteosarcoma have been reported, reports of parosteal osteosarcoma following radiation therapy are rare.
