Lung metastasis 21 years after initial diagnosis of osteosarcoma: A case report

Abstract

Introduction. To the best of our knowledge, this case report describes the longest disease-free interval between primary diagnosis and metastatic recurrence of an osteosarcoma. Case presentation. A 35-year-old Caucasian American man presented with asymptomatic lung metastases 21 years after being diagnosed and treated for lower extremity osteosarcoma. He underwent curative lung resection, but 2 years thereafter developed metastatic disease in the scapula and tibia and, after resection and chemotherapy, is in remission 1 year later. Conclusion. This case highlights the importance of long follow-up periods and continued surveillance of osteosarcoma patients after initial curative treatment. © 2009 Halldorsson et al; licensee BioMed Central Ltd.
