Extraosseous osteogenic sarcoma is a rare and highly malignant neoplasm. A 57 year old male patient presented with a mass in the abdomen involving the left lumber region. The ultrasound and computerized tomography (CT) scan showed a large mass arising from upper pole of the left kidney. Left radical nephrectomy was performed in April 1995. Histopathology report revealed a high grade extraosseous osteogenic sarcoma. Patient was disease free for 23 months. Although the prognosis is grave, aggressive surgical treatment with adjuvant therapy helps in prolonging the survival.

Secondary osteosarcomas of the maxilla/premaxilla are extremely rare. We describe a case of a 24-year-old man with a metastasis of osteosarcoma to the premaxilla. The patient had undergone hip disarticulation followed by adria based chemotherapy for chondroblastic osteosarcoma of the proximal right femur ten years ago. The metastatic work up did not show liver or lung metastasis. The patient underwent premaxillectomy in February 1999. The histopathology revealed a chondroblatic osteosarcoma consistent with metastasis in the clinical setting. The patient was disease free at the end of five months.
