title: Osteogenic sarcoma in a child.
abstract: Osteogenic sarcoma is a malignant bone tumor that occurs more frequently in long bones of the extremities, mainly in the second and third decades of life. It rarely occurs in children younger than 5 years of age. We describe the case of a 3 9/12 years old boy, who is one of the youngest patients described in the literature. This patient had an aggressive disease, with pulmonary metastases at the time of diagnosis. The disease progressed rapidly despite surgery and chemotherapy. Diagnosis was delayed probably because of the unusual presentation of this disease at this age.
