Introduction: osteosarcoma is the second primary malignant tumor of bone most frequent after the multiple myeloma; it represents 20% of all the bony sarcomas approximately. Around 560 children and adolescents are affected annually by this tumor in the United States of North America. Development: a bibliographical review on osteosarcoma was conducted, where emphasis was made in the intramedullary and surface varieties, it is made reference to each tumor variety, with more importance in the intramedullary ones that are the most aggressive and frequent, also to the most useful laboratory exams for diagnosis as well as to the classification and the stage applied to this tumor. Later on the varieties of treatment both chemotherapy and surgical, their modalities, time of application, combined use and associated factors to the bad prognosis are approached.
