Web osteosarcomas are the most common primary bone tumor and third most common cancer among children and adolescents, behind lymphomas and brain cancers. Web periosteal sunburst spiculation is a peculiar radiographic feature of osteosarcoma, and it represents a reactive ossification resulting from the action of normal osteoblasts rather than tumor cells. Five such cases are reported and discussed, i. Web the sunburst appearance occurs when the lesion grows too fast and the periosteum does not have enough time to lay down a new layer and instead the sharpey's fibers stretch out perpendicular to the bone.
