heterotopic ossification.

Figs. 1-A and 1-B: Plain radiographs and computed axial tomography scan of the right forearm, made one year after the patient sustained an electrical shock, demonstrating massive areas of

heterotopic ossification.



Fig. 2 Digital subtraction arteriogram, made ten years after the injury, showing a distinct tumor blush, with neovascularity arising from the brachial artery, in the region of a bleeding,

nonhealing wound (arrows).



Fig. 3 Lateral radiograph of the right forearm and elbow, made ten years after the electrical injury, revealing a new radiolucent area with an associated soft-tissue mass (arrows).



Figs. 4-A and 4-B: Computerized axial tomography scans of the right forearm, made when the patient was first seen by us.



Fig. 4-B: Scan made through the proximal part of the forearm, showing a soft-tissue mass arising from an area of heterotopic bone with areas of bone (solid arrows) and apparent fluid-filled

spaces (open arrows).



Figs. 5-A through 5-D: Histological appearance of the tumor obtained from the amputation specimen (hematoxylin and eosin).



Fig. 5-B Photomicrograph showing the telangiectatic osteosarcoma arising from metaplastic bone.



Fig. 5-C High-power photomicrograph showing malignant cells surrounded by primitive osteoid (x 10).



Fig. 5-D High-power photomicrograph showing the telangiectatic pattern (x 10).
