title: Synchronous multicentric osteosarcoma in Puerto Rico: a pediatric case report.
abstract: Synchronous multicentric osteosarcoma is a very rare condition that might be confused with metastatic osteosarcoma. We report the first pediatric case of synchronous multicentric osteosarcoma reported in the Puerto Rican. The child presented with multiple osteoblastic bone lesions followed by right upper lid ptosis. Orbital CT-Scan showed a lytic lesion involving the sphenoid bone. Management consisted of chemotherapy for forty-two weeks after which she remained without new secondary bone lesions.
