Osteosarcoma, a highly malignant neoplasm arising from bone, is generally seen at the metaphyseal ends of long bones in a patient from 10 to 30 years old. In the oral and maxillofacial region, osteosarcoma is found more often in the mandible than in the maxilla, the later of which has an incidence of only 1%. We describe here a rare case of osteosarcoma of the maxilla. The patient, a 41-year-old woman, had mental retardation due to arsenic poisoning, and was referred to our clinic for a tumor of the maxilla on right side. After receiving informed concent from the patient's family, conservative treatment with chemotherapy (ADR+CBDCA) and surgical partial resection of the tumor mass were performed. However, agressive recurrence of the tumor occurred and the patient died 5 months after initiation of treatment.
