BUSTAMANTE, Jorge et al. Synchronous multicenter osteosarcoma in a pediatric patient: Report of a case. Acta méd. Peru [online]. 2018, vol.35, n.2, pp.127-132. ISSN 1728-5917.

Osteosarcoma is a common malignancy affecting bones. However, the multicenter or multifocal variety is a rare condition. Also, if at the time of diagnosis more than one lesion is identified, then the ‘synchronous’ term is added to the case definition. We present the first case described in Peru of a 9-year old patient who was referred to our institution with radiological images suggesting a bone malignancy in her distal right femur. Afterwards, a synchronous multicenter sarcoma was diagnosed with biopsy and image studies. She received triple chemotherapy with ifosfamide, doxorubicin, and cisplatin, but there was no improvement in her clinical status. Later she developed lung metastases and she received palliative therapy with cyclophosphamide. In conclusion, synchronous multicenter osteosarcoma is a highly aggressive bone malignancy with a poor prognosis. Our experience with triple therapy did not lead to a good clinical response. We suggest individual assessment for treating this variant
