Medication-related osteonecrosis of the jaw in a paediatric patient taking denosumab: a case report.

Medication-related osteonecrosis of the jaw (MRONJ) is a known complication of antiresorptive and anti-angiogenic therapies in adults. Increasingly, these drugs are being prescribed for children with a variety of conditions, such as osteogenesis imperfecta and cancers of the bone. Review of the literature, however, reveals no reported paediatric MRONJ cases to date. We present such a case in a nine-year-old female patient with a vertebral aneurysmal bone cyst, who received dental extractions subsequent to denosumab therapy.
