Introduction:
Lipomata are soft-tissue mesenchymal neoplasms that are benign in nature and often asymptomatic. Lipomata commonly occur in the body, however, only 1%-5% are identified within the oral cavity, and lipomata with osseous metaplasia account for <1% of all lipomata.
Materials and methods:
A PubMed literature review designating search terms including "oral" and "parosteal lipoma" or "lipoma with osseous metaplasia" or "ossifying lipoma" or "osseous lipoma" was conducted.
Results:
The literature review identified two previous reports of parosteal localization of lipomata in the mandible and 22 cases of lipomata with osseous metaplasia within the oral cavity.
Conclusions:
With the initial suspicion of a more malevolent diagnosis, this rare entity, with only two other cases identified, is important to consider in the clinician's differential diagnoses.
