Benign bone tumour. Light micrograph of a section through a non-cancerous osteoid osteoma. The tumour is composed of unmineralized bone matrix (osteoid,orange),newly-formed bone (uniform pink,centre right) and bone-forming osteoblast cells (pink-staining cells,centre). Osteoid osteoma occurs in children and young people,in bones of the leg,arm or spine. It is painful and,depending on location,may cause spinal curvature (scoliosis) or joint problems. Treatment with aspirin or similar anti-inflammatory drugs can relieve the pain. The tumour will stop growing and heal as the skeleton matures,but surgery may be needed before then.
