Peripheral Osteoma of the Mandibular Condyle—Case Series. Dent J (Basel) 2022; 10:dj10100182.

Abstract
The purpose of this article is to present four new cases of peripheral osteoma of the mandibular condyle and the literature review. A retrospective study of files from our Department of Oral and Maxillofacial Surgery over the last 6 years revealed four cases of peripheral osteomas located in the area of the mandibular condyle. Diagnostic procedure included clinical, radiographic, and histologic criteria. Gardner’s syndrome was excluded from patient history and clinical evaluation. One patient had only an aesthetic disturbance, with facial swelling, and the other three patients presented disturbances of the mandibular function, including deviation during mouth opening along with malocclusion. Three of the patients were male and one was female; all were of middle age (45–65 years old). The proposed surgical treatment was accepted by half of the patients, while the remaining half declined the operation after a confirmation of the diagnosis. Peripheral osteomas of the maxillofacial region are uncommon, and some cases with multiple osteomas are related to Gardner’s syndrome. An osteoma of the mandibular condyle is very rare and surgical treatment is challenging for the surgeon with regards to the approach selection and the related complications. In the two cases that accepted the proposed surgical treatment, no recurrence and no complication was observed.

A case of benign osteogenic tumour in Homo naledi: Evidence for peripheral osteoma in the U.W. 101-1142 mandible. INTERNATIONAL JOURNAL OF PALEOPATHOLOGY 2018; 21:47-55.

Abstract
The reported incidence of neoplasia in the extinct hominin record is rare. We describe here the first palaeopathological analysis of an osteogenic lesion in the extinct hominin Homo naledi from Dinaledi Cave (Rising Star), South Africa. The lesion presented as an irregular bony growth, found on the right lingual surface of the body of the adult mandible U.W. 101-1142. The growth was macroscopically evaluated and internally imaged using micro-focus x-ray computed tomography (μCT). A detailed description and differential diagnosis were undertaken using gross and micromorphology, and we conclude that the most probable diagnosis is peripheral osteoma - a benign osteogenic neoplasia. These tumours are cryptic in clinical expression, though they may present localised discomfort and swelling. It has been suggested that muscle traction may play a role in the development and expression of these tumours. The impact of this lesion on the individual affected is unknown. This study adds to the growing corpus of palaeopathological data from the South African fossil record, which suggests that the incidence of neoplastic disease in deep prehistory was more prevalent than traditionally accepted. The study also highlights the utility of micro-computed tomography in assisting accurate diagnoses of ancient pathologies.
