Abstract:
Dedifferentiated parosteal osteosarcoma is a rare tumor and is even rarer when involving the skull bones. We present a case of a 57-year-old man with a partially ossified progressive enlarging left skull mass in the left temporoparietal region, with erosion of the outer table. Radiological diagnosis of dedifferentiated parosteal osteosarcoma was suggested, and histopathology confirmed the diagnosis.
