Radiation‐induced sarcomas are recognized complications of radiation therapy and are associated with poor prognosis. Radiation‐induced osteosarcoma is one of the rare types of radiation‐induced sarcomas, with the risk of radiation‐induced osteosarcomas being only 0.01%–0.03% among all patients treated with radiotherapy. There have been only four reported cases of radiation‐induced osteosarcomas after radiotherapy for gliomas. Here, we report a unique case of radiation‐induced osteosarcomas arising on the skull and extending to the skin, with a short latent period. We also review the clinical features of the previously reported cases.
