abstract: A case of primary malignant mesenchymoma of bone is reported. It's a very rare kind of tumor of which only four cases were previously reported in the literature. It's a malignant neoplasm where histological aspects of both liposarcoma and osteosarcoma coexist. Prognosis appears to be similar to that of osteosarcoma.
