Osteolipoma: a painless mandibular mass

Abstract

a b s t r a c tLipoma 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.

Osteolipoma: An Extremely Rare Hard Palate Tumor

“…Pathogenetically, the development of lipoma has been linked with hereditary conditions, trauma as well as obesity and generally, it is composed of mature white adipocytes [1,8]. Nevertheless, this tumor can occasionally show changes depending upon the predominance of other mesenchymal elements [9]. One such extremely uncommon variant of it is osteolipoma, which has been described as a lipoma containing osseous elements.…”
