Intraosseous Lipoma of the Mandibula: A Case Report and Review of the Literature

Bilateral intraosseous lipoma of the maxillary tuberosity: A challenging entity

Lipomas can occur anywhere in the body where fat cells are present; however, intraosseous lipomas are rare. Although solitary lesions have already been reported in the gnathic bones, to the best of our knowledge, this is the first case of bilateral intraosseous lipoma. A 62-year-old woman was referred for evaluation of a swelling on both maxillary tuberosities. The radiographic examination showed a mixed radiolucent-radiopaque image with ill-defined borders on the right side of the maxilla, and an ill-defined radiolucency on the left side. Histologically, both sides revealed numerous mature adipocytes surrounded by immature bone and dystrophic calcification. The patient remains under follow-up and free of disease for 8 months. Due to the rarity of the intraosseous lipomas in the jaws, a literature review of the published cases was performed jointly with this unique case report.

Intraosseous lipoma of the jaws: Review of the literature and rare case report

BACKGROUND

Lipoma is a benign tumor that arises at the expense of mature adipose tissue, it can occur anywhere in the body that contains adipose tissue. However, the intraosseous lipoma is considered a rare bone tumor, that affects the long and flat bones, but it is uncommon in the jaws. Usually, diagnosis based on clinical and radiographic features is insufficient and histopathology analysis is of utmost importance for the final diagnosis.

CASE PRESENTATION

In this article, we present a case report of a 28-year-old female patient who visited the dentist with the intention of extracting an impacted tooth. She had no medical history with medications or genetic diseases. The tooth was extracted with a small soft mass that was subjected to histological analysis and it was found to be an intraosseous lipoma.

DISCUSSION

Intraosseous lipoma is a rare tumor of the oral cavity, and it can be difficult to diagnose when only clinical and radiographic features are based, and the definitive diagnosis is based on histological examination. The treatment is complete surgical excision.

CONCLUSIONS AND LITERATURE REVIEW

30 cases were discovered and archived since 1948 until now, most of them were in the posterior region of mandibular, and the infection of females is higher than males with different final sub-diagnosis of types of intraosseous lipoma.

Intraosseous Lipoma: A Report of a Case in the Mandibular Symphysis Region

Intraosseous lipomas are benign lesions of the bone. In the jaws, they are very rare and in most cases incidentally discovered on panoramic radiographs taken in dental practice. They are usually asymptomatic and appear radiologically as a radiolucent image sometimes including some radio-opacities. Histologically, they consist of mature adipose tissue associated with variable degrees of necrotic fat and calcification. In this report, we describe a case of intraosseous lipoma in the mandibular symphysis region of a 37-year-old female as well as the treatment adopted.

Oral lipoma: Case report and review of literature

Lipoma is a benign neoplasm that primarily affects the middle-aged individuals and has a rare oral cavity occurrence. Given its noninvasive behavior and low recurrence rate, surgical conservative management should be regarded as the best therapeutic option. This paper highlights two patients along with their improved conditions following the treatment.

Intraosseous spindle cell lipoma of the mandible: case report

We describe what is to our knowledge the first reported intraosseous spindle cell lipoma of the mandible. It is the first spindle cell lipoma we have seen that shows dental resorption, and the largest that we have seen published (60×30×20mm).
