Osteoid Osteoma
摘要
Osteoid osteoma is a benign, slow growing osteogenic tumor with over-formation of unmineralized bone matrix [1–4]. It occurs mostly in the long bones of the spine and lower extremities, but may also occur in atypical sites such as the jaw bone [5–8]. The typical clinical features are small size, a tendency to self-limiting growth, and disproportionate pain.
