Peripheral ivory osteoma of the mandible in a young female patient.

Osteoma is an uncommon benign neoplasm composed of mature bone. Growth is slow and continuous and located principally in the cranio-maxillo-facial region, and can be central (endosteal) or peripheral (periosteal). Osteomas can be solitary or multiple masses, and they are generally asymptomatic. We discuss a case of ivory osteoma of the mandible in a 35-year-old female, which was present at the left body of the mandible since she was 10 years old, and was gradually increasing in size. The osteoma was removed surgically through an intraoral approach, and no recurrence was observed.
