[Pediatric mandibular myofibromatosis].
BACKGROUND
Pediatric myofibromatosis is a rare tumor in neonates and children. Two forms are described, solitary and multicentric, the solitary type is more common and is localized mainly on the head and the neck, mandible involvement is rare. The aim of this article was to report the anatomoclinical and therapeutic features of this pediatric tumor in a case as well as its follow-up.


METHODS
A 10-year-old girl was brought to consultation for a lower left gingival swelling 5 cm in diameter, forming a unit with the mandibular bone. The volume had gradually increased over the last 12 months. Imagery revealed the presence of an osteolytic tumor benign in aspect, but locally aggressive. Conservative surgery was performed. The diagnosis of pediatric myofibromatosis was confirmed. Evolution was excellent and after three years of follow-up, there was no evidence of relapse.


CONCLUSIONS
Pediatric myofibromatosis often presents as a painless, well-circumscribed, solid nodule. Imagery is very useful to assess lesion extension and for the therapeutic follow-up. The diagnosis is made on anatomopathological findings and immunohistochemical assessment. The treatment of the solitary myofibromatosis is primarily surgical and its prognosis is excellent contrary to the multicentric form.
