title: Dedifferentiated chondrosarcoma with features of telangiectatic osteosarcoma.
abstract: We describe a 44-year-old female with a known history of a solitary osteochondroma of the scapula followed on X-ray for five years. She then presented with a rapidly growing lump. Imaging studies confirmed the presence of an aggressive looking lesion. Excision was performed and pathology showed a dedifferentiated chondrosarcoma with features of a telangiectatic osteosarcoma.
