Background:

In the national literature there is not much information about this bone lesion. Objective: to update knowledge in relation to this bone lesion.

Methods:

the search and analysis of the information was performed over a period of four months (June 1st, 2020 to September 30th, 2020) and the following words were used: non-ossifying fibroma, and fibrous cortical defect. From the information obtained, a bibliographic review of a total of 247 articles published in the PubMed, Hinari, SciELO and Medline databases was carried out using the search manager and EndNote reference manager, of which 40 selected citations were used to perform the review, 38 of them of the last five year, four books were consulted.

Results:

the most frequent location is mentioned, as well as the clinical presentation forms. Imaging studies and the interpretation of their results are described. In relation to the differential diagnosis, a series of entities with very similar clinical and imaging characteristics are compared. Reference is made to the macro and microscopic characteristics, in addition to the type of treatment and complications.

Conclusions:

the non-ossifying fibroma is an entity that presents itself with relative frequency. The imaging characteristics are typical and eccentricity of the lesion stands out among them. The treatment depends on the lesion and goes from the simple observation to the surgical one.
