Solitary intraosseous myofibroma: a rare case diagnosed from mandibular fracture.

Intraosseous myofibroma is a rare tumor of benign nature, slow growth, and low morbidity. The aim of this article is to report a case of pathologic fracture associated with the incidental diagnosis of myofibroma in the mandible of an adolescent. A 15-year-old girl reported that she experienced a physical assault resulting in facial injuries 1 month previously and had since experienced severe pain, malocclusion, and chewing difficulty. The cone beam computed tomographic examination revealed multiple features suggestive of pathologic fracture associated with a hypodense lesion with lobulated limits, as well as expansion and thinning of the cortical bone in the left mandible. The histopathologic diagnosis of the lesion indicated myofibroma. Treatment consisted of enucleation and curettage of the lesion with reduction and internal fixation of the fracture. After 18 months, the osteosynthesis plates and an impacted mandibular third molar were removed. Curettage of the lesion in association with treatment of the mandibular fracture proved to be effective for both bone consolidation and absence of recurrence while restoring mandibular functionality.
