[Mineral and trace element determination in human osteosarcoma. Case report].

The concentrations of calcium and magnesium, and of the trace elements iron, copper, manganese and zinc were determined in the amputation specimen of a 25-year-old patient with osteosarcoma and compared with the tumor-free, normal bone tissue. Not only the concentrations of calcium and magnesium, but also those of the trace elements were significantly higher in the osseous portion of the tumor. The periosseous concentrations of trace elements iron, copper and zinc were also significantly higher in the tumor than in the normal bone tissue.
