The myofibroma is a tumor that presents predominantly in head and neck, oral cavity are rare and even more intraosseous; in the mandible represent 12% of all soft tissue tumors in children. The presence of this injury is rare, affecting children and young people, it is noteworthy that in the mandible are even less frequent. Histopathologically looks similar to a hemangiopericytoma. The definitive diagnosis is based immunohistochemical panel consisting of antibodies to vimentin, dismina, CD34, HHP-35, SMA and S-100 P; giving positive vimentin and HHF-35 dismina with marker muscle actin smooth for the identification of myofibroblasts. Objective: Retrospective, longitudinal, observational study, from three cases of pediatric patients. Discussion: Intraosseous mandibular myofibroma is a rare tumor that only occurs in childhood, clinical and radiological features may suggest a presumptive diagnosis of ameloblastoma or myxoma, while histopathological diagnosis can be confused with hemangiopericytoma. Therefore, it is indicated immunohistochemical tests to achieve a definitive diagnosis. Conclusions: Treatment of children always try to be conservative because in this type of injury recurrence is low, and for this reason it is important to highlight the clinical course of lesions that may arise with respect to the oral cavity and bones of the head. Since they are often initially treated as infectious processes and unduly long, its diagnosis and treatment are delayed, complicating the course of the injury and treatment because this would have to be more extensive or mutilating the pediatric patient. Hence the importance of early detection and appropriate for any type of injury in the oral cavity or in the bones of the facial region.

Key words: Intraosseous jaw myofibroma, children.
