Primary renal osteosarcoma with systemic dissemination

Abstract EN

Primary renal osteosarcoma is an uncommon disease, which, unlike its skeletal counterpart, presents mostly in adults, and is generally diagnosed late due to its non-specific features and intra-abdominal location.

Even if the disease is localized at diagnosis, it follows an aggressive course despite radical surgery and adjuvant treatment.

We report a case of renal osteosarcoma in a 65-year-old female, who developed regional recurrence, and lung and bone metastases soon after radical nephrectomy for localized disease.

Chemotherapy was ineffective in controlling systemic disease.
