A distinct fibro-osseous lesion of the jaws affecting the maxilla.

The differential diagnosis of fibro-osseous lesions (FOL) presents oral clinician stomatologists with a challenging task because of their similar clinical, radiographic and histopathological behavior that will also hinder the therapeutic planning. Presentation of case to describe the clinical, radiographic and histopathological features of an unusual case of FOL presented by the patient, a Black woman, and the results obtained with the conservative surgical treatment and 3-month follow-up. The presence of cementum in the histopathological analysis of cemento-osseous dysplasias, according to the current literature, is an important factor for the diagnosis of this lesion. Considering the characteristics presented by this particular case, we could suggest another entity that could be named a benign cemento-osseous lesion with adult onset. Some occurrences, as in the present case, do not fit properly into the current World Health Organization classification, thereby generating some doubts concerning the correct management of these patients. Conservative surgical treatment is the first choice in the management of these lesions due to their self-limiting nature, which show a behavior of clinical involution.
