Purpose:
Renal osteosarcoma may arise as a metastasis from a primary bone osteosarcoma or as a primary renal tumor. Metastatic renal osteosarcoma has been found at autopsy in approximately 10% of patients who die of this disease.
Patient And Methods:
A case report of a young Chinese patient presenting with acute onset of renal infarction and hemorrhage from a renal metastasis of osteosarcoma is presented, as well as a review of the literature.
Results:
Some patients with solitary renal metastatic osteosarcoma may have long-term disease-free survival after nephrectomy. Early diagnosis and thus increased awareness of this condition is important.
