Traumatic fibromas are frequently found in the oral cavity. They are characterized by a localized proliferation of dense collagen fibers resulting from regional trauma, rather than representing a true neoplasm. This case report describes a patient with a clinical and histopathological diagnosis of traumatic fibroma, in which the lesion presented a considerable and unusual growth, leading to facial asymmetry. The lesion, with several months of evolution, showed a significant size, for which the therapeutic approach consisted of total excision. After one year of follow-up, there was no recurrence of the lesion. Surgical excision was considered for the treatment of traumatic oral fibroma. It is concluded that it is important to identify the etiologic factor and proceed with its elimination to avoid recurrence.

Fibrous dysplasia is a benign and progressive bone disease of genetic basis that can affect one or several bones. Its high incidence in the pediatric age served as a basis for it to be previously considered exclusive to this stage; however, there are reports to date that show its development and later growth in the second decade of life. When associated with endocrine imbalances and café-au-lait spots, it is part of the McCune-Albright syndrome. The present case report shows the clinical and radiologic features of the oral-facial region of an adult patient with McCune-Albright syndrome. Lesions in the jaws affect the morphology and cause dysfunction. At the dental level, the changes produced result in malocclusion and structural defects. Radiological studies showed changes with mixed density and ground glass pattern.
