Tumor relapse and pulmonary metastasis, especially unresectable lesions, are the major cause of poor prognosis of patients with osteosarcoma. Anlotinib, a novel small-molecule tyrosine kinase inhibitor (TKI), has been proved to have desirable anti-tumor effects via blocking VEGFR2 and PDGFRβ phosphorylation in several tumors, including non-small cell lung cancer and soft tissue sarcoma. In this study, we presented a case of giant delayed pulmonary metastasis of osteosarcoma which was effectively treated by anlotinib. CT scan of this
