ABSTRACT

A lipoma is a common benign tumor that generally arises in soft tissue, and rarely occurs in bone. Although some cases of intraosseous lipoma have been reported, lipoma of the jaw bones is extremely rare. We report a rare case of lipoma occurring in the mandible. A 24-year-old woman was referred to our department because of a radiolucent lesion in the right side of the mandible. Clinically, the lesion was diagnosed as a cyst, and extirpation of the lesion was performed with the patient under general anesthesia in April 2001. The lesion consisted of 14 smaller tumors, which were elastic, yellow, capsulated, and soft. The prognosis was good, and there was no sign of recurrence at an examination 80 months after the operation. Keywords: lipoma, intraosseous lipoma, mandible.
