Lipoma is a common soft-tissue tumor. There are only very few reported cases of intraosseous lipoma of the jaws in the literature. Intraosseous angiolipomas are even rarer. The exact nature of these lesions is debatable, but it is widely accepted that they represent true benign tumors. These are slow-growing tumor consisting of a mass of mature fat cells. When the vascular component within these tumors is a prominent feature, they are considered to be angiolipomas. The cause of these lesions is uncertain. Clinically, intraosseous lipoma may be asymptomatic, may cause swelling, or may show neurologic signs such as hypesthesia or paresthesia, as was manifested in this case. Radiographically, the lesion usually appears as a well-circumscribed radiolucency. The diagnosis of intraosseous lipoma of the mandible may be a challenge, due to its rarity and clinical similarity with many other radiolucent jaw lesions; therefore, the histopathological examination is always required. Here, we report a case of intraosseous angiolipoma of mandible in a 21-year-old female patient.
