Rare presentation of mandibular intraosseous cell Lipoma

Abstract Lipomas may be located in all parts of the body and may be confused clinically with other soft tissue masses. They infrequently occur in the head and neck. Surgical excision of a lipoma is often used as the definitive treatment modality, and alternative treatments described for lipomas range from liposuction to steroid injections. In the present study, a 38-year-old woman who was initially referred by her dentist due to a myofascial pain is described. An incidental finding (8*5mm mass) was successfully removed and diagnosed as intraosseous cell lipoma. The surgery produced excellent painless results and no functional or neural impairment. Clinically and radiographically, the tumor demonstrated inferior alveolar canal involvement. Such unique tumor characteristics never been previously reported, invalidating prior theories suggested for the etiological factors of this rare tumor. The current case report suggests a clear etiology for this tumor as a true primary benign neoplasm.
