[Osteoblastoma of the dens axis in a 14-year-old boy. A case report].

We present a case of osteoblastoma of C1 in a 14-year-old boy. The case deserves attention because it is a conglomerate of issues important from the point of view of clinical practice. Key issues associated with this interdisciplinary pathology are discussed, such as diagnostic problems, stabilisation of the cervical spine and extensive surgery associated with the risk of severe bleeding in a Jehovah Witness. A short review of pertinent literature is included.
