[Odontogenic myxoma in children : an exceptional locally aggressive lesion].

Odontogenic myxoma is a histologically benign and aggressive tumour of the maxillofacial region. It mainly affects young adults and remains exceptional in children. Due to its local invasive nature, it is difficult to differentiate this tumour from malignant neoplasma and from other destructive odontogenic benign tumours. Imaging plays an essential role in the initial exploration and follow-up. Its management is still a challenge today, due to its aggressive potential and its significant risk of recurrence in children among whom extensive surgical treatment involves significant morbidity in children.
