Primary osteosarcoma of kidney with liposarcomatous elements.
Extraosseous osteogenic sarcomas are unusual tumors that are seldom diagnosed. Although primary renal osteogenic sarcoma has been reported, and is described in the Armed Forces Institute of Pathology fascicle, most clinicians are unaware of its existence. We describe a patient with this disease to remind clinicians of this tumor, its presentation and rapid evolution.
