Metastatic infiltration of the dental pulp by medulloblastoma

Medulloblastoma is an infratentorial primitive neuroectodermal tumour. It is the most commonly occurring brain tumour of childhood, accounting for 15-20% of all paediatric tumours. Extracranial metastasis is rare, but may involve the skeleton. Jaw lesions, however, have never been described. A case is reported of metastases of a medulloblastoma to the jaw including the dental pulp.
