title: Pseudomalignant osteoblastoma versus arrested osteosarcoma: a case report.
abstract: A case is presented which is interpreted as a histologically pseudomalignant osteoblastoma. This diagnosis is supported by the clinical and radiologic findings. Arguments are presented in support of this diagnosis as against an osteogenic sarcoma with an arrest in growth, although this latter diagnosis cannot be completely excluded.
