Key result
Right radical nephrectomy confirmed metastatic condroblastic osteosarcoma in a 20-year-old male presenting with a renal mass two and a half years post-treatment for distal femur osteosarcoma.
Why the study?
Renal metastasis of osteosarcoma is rare, with a paucity of reported cases in the literature.
Case Report (n=1)
Renal metastasis of osteosarcoma is a rare entity that can present with flank pain and haematuria after pulmonary recurrences.
Renal masses with hematuria in osteosarcoma survivors merit consideration of metastasis; extends sparse literature on this rare site.
Renal metastasis of osteosarcoma is a rare entity, with paucity of reported cases in the literature. We report a case of a 20-year-old gentleman who was diagnosed with right distal femur osteosarcoma, complicated with multiple pulmonary recurrences. At two-year-and-a-half interval post-treatment completion, the patient developed right flank pain and frank haematuria. Contrasted abdominal computed tomography revealed a right renal mass with calcification and perinephric haematoma. A right radical nephrectomy was undertaken and histopathological examination showed metastatic condroblastic osteosarcoma. A literature review on renal metastasis secondary to osteosarcoma was performed and we present a report and discussion of these cases.

Ooi et al. (2022) conducted a case report in Renal metastasis of osteosarcoma (n=1). Right radical nephrectomy was evaluated. Right radical nephrectomy confirmed metastatic condroblastic osteosarcoma in a 20-year-old male presenting with a renal mass two and a half years post-treatment for distal femur osteosarcoma.
