IMAGE DESCRIPTION:
Low power photomicrograph shows the cystic lining of the unicameral bone cyst which is composed of benign fibrous tissue lying directly on the thinned out cortical lining of the cyst. The macrophage activity on the surface of the bone that is causing osteolytic destruction indicates an active phase and makes the cyst more amenable to injection with methylprednisolone to inhibit this macrophage activity.
