[Myofibroma of the mandibule: a case report]

Myofibromatosis is a rare tumor. 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 recent observation of a patient with a myofibrome of the mandible has given the opportunity to conduct an analysis and review of the literature of this disease rarely encountered.

We report a case illustrating solitary myofibroma of the mandible in a 16 year old man.

The histological diagnosis was done on the identification of the spindle-shaped tumoral proliferation and the positive expression of the anti-vimentine, anti-smooth, muscle actin anti desmin. The treatment was surgical.

myofibromatosis often presents as a painless, well-circumscribed, solid nodule. Imagery is very useful to assess lesion extension and for the therapeutic followup. 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.
