Osteolipoma: a painless mandibular mass

Abstract

Lipoma is the most common benign mesenchymal soft tissue neoplasm in adults. It is rarely seen in the oral cavity and comprises 1–4% of all benign oral lesions. There are different types of lipomatous tumors that contain other predominant mesenchymal elements such as cartilaginous/osseous tissues. Osteolipoma is a rare histopathologic variant of lipoma accounting for less than 1% of all lipomatous cases. Eight cases of this type of lipoma were reported in the mandibular buccal vestibule. The present study aims to report a rare condition: a patient with osteolipoma situated in the mandibular region. In addition, a literature review is presented.
