Parosteal osteosarcoma is a rarely encountered variety of osteosarcoma which is differentiated from a common intramedullary osteosarcoma. The clinical appearance and pathological observations often indicate a benign tumor. We reported on a case of mandibular parosteal osteosarcoma and reviewed the literature concerned in this article. A 61-year-old woman was affected by painless swelling of the alveolar bone adjacent to a left lower molar. The first and second biopsies indicated osteoma and reactive bone formation respectively. As the tumor enlarged rapidly, marginal resection of the mandible was performed. Tumor recurred on the left mandibular condyle in the 9 th month following surgery. She then underwent hemimandiblectomy and reconstruction with an alumina ceramic jaw. The tumor was finaly diagnosed as a parosteal osteosarcoma by its appearance and radiographic findings. Her postoperative course has been uneventful to date. It is concluded that wide excision is recommended for such cases.
