# A Rare Case of Peripheral Exophytic Osteoma of the Mandible Arising From an Extraction Site: Cone-Beam Computed Tomography (CBCT) Findings

## TL;DR

This paper discusses a rare case of a benign bone tumor in the jaw, highlighting its clinical features and the importance of differential diagnosis.

## Contribution

The paper presents a rare case of peripheral exophytic osteoma of the mandible and emphasizes its clinical significance.

## Key findings

- Peripheral osteomas are uncommon, with a higher prevalence in the mandible compared to the maxilla.
- Males are more frequently affected by osteomas, and these tumors can be associated with Gardner syndrome.
- Differential diagnosis is crucial due to the potential malignant progression of gastroenteric polyps linked to Gardner syndrome.

## Abstract

A benign osteogenic tumor made up of mature, well-differentiated bone tissue is called an osteoma. Jaw solitary peripheral osteomas are an uncommon occurrence. The mandible is affected more frequently than the maxilla, and the lingual side of the body, the angle, and the inferior border of the jaw are the sites of highest preference. Males are more likely than females to be impacted by osteomas, which can strike at any age. Patients with osteomas should be considered to have Gardner syndrome. This condition includes many embedded or supernumerary teeth, skeletal abnormalities such as osteoma and hyper calcification of the maxillary bones or skull, skin and soft tissue tumors, and gastroenteric polypus. Differential diagnosis is crucial since the development of gastroenteric polyps, which have a potentially malignant progression, occurs before oral and maxillofacial symptoms emerge. Mandibular osteomas are uncommon; even rarer is a massive osteoma with a prevalence of 0.01-0.04% of the population. That's the reason this is being discussed in this article. The primary differential diagnosis and pertinent clinical information from previously published literature are also included in this article.
