[Primary neuroblastoma of the mandible. Apropos of a case]

Concerning an observation of mandibular neuroblastoma, the problem of a probable primary localization of this neurocristopathy is raised on the face level. Actually, classically speaking, it can only be a question of metastasis revealing a tumor initially located in the abdomen, the thorax, or more rarely in the pelvis or the neck. However, the evolution of the lesion under treatment leading to complete cure within three years denies the secondary nature of the process. Related to the three other cases in the world that have so far been published, our observation enables to assert the reality of the primary development of a neuroblastoma on the mandibular level. The coherent reasoning is founded on the role of neural crests in facial embryogenesis whose vitiation offers a logical explanation to this exceptional phenomenon.
