A Rare Case of Intraosseous Fibrolipoma of the Mandible: Diagnosis and Treatment

Abstract

Lipomas are common soft tissue tumors. Intraosseous lipoma is a rare lesion that constitutes not more than 0.1% of bone tumors. It can occur anywhere in the body and there have only been a few cases found in the mandible. Intraosseous fibrolipoma of the jaw is an uncommon histological variant of the classic lipoma and to the best of our knowledge only one case has previously been reported in the literature. The cause of this lesion is uncertain. Clinically the lesion is generally asymptomatic and its radiographic feature is a well-defined radiolucency. Surgery is the treatment of choice. We present a case of an intraosseous fibrolipoma in the right mandibular ramus in a 25-year-old female.

Lipoma óseo: reporte de caso y revisión

“…economía. La primera descripción se realizó en 1880 1,2 . El 70% de estas lesiones se localizan en la extremidad inferior y, debido a su rareza, se confunden con entidades como el fibroma no osificante, el quiste simple óseo, el quiste óseo aneurismático, la displasia fibrosa ósea, el tumor de células gigantes, los infartos óseos y los tumores condroides.…”

Clinicoradiographic Features and Histopathologic Variations of Intraosseous Lipoma: Report of a Case and Review of the Literature

“…However, in the 3 Case Reports in Dentistry present literature review, about 43.33% of patients were under 40 years old; thus, fatty degeneration of bone marrow can be ruled out. Conservative surgery is the treatment of choice, and recurrence or malignant transformation of IOL in the maxillofacial region has not been reported in the literature [3]. However, malignant transformation of IOL in other sites has been reported [16].…”

“…There are few reports of IOL in the jaw, and the cause of this lesion is not known [1,[3][4][5][6][7][8]. It is usually asymptomatic; although pain, swelling, and paraesthesia have been reported [1,4].…”

“…Fibrolipoma is a variant of conventional lipoma composed of mature fat cells intermixed with fibrous connective tissue. Conservative surgery is the treatment of choice [ 3 ]. This paper presents a case of intraosseous fibrolipoma of the mandible afflicting a 39-year-old man and reviews the literature on this rare lesion.…”

Bone lipoma: case report and review

“…Bone lipomas account for 0.1% of all bone tumors and can develop in all bones of the human body. The first description was made in 1880 1,2 . Seventy percent of these lesions are located in the lower limbs and, owing to their rareness, they are confused with other entities such as non-ossifying fibroma, simple bone cyst, aneurysmal bone cyst, bone fibrous dysplasia, giant-cell tumor, bone infarcts and chondroid tumors.…”
